    Guys, I want to bang my head with Wall. Have you ever lost your keys, what do you do, find it everywhere, look at it again and again at same place or nearby. Same is the issue with me ????

    9th generation corolla Xli, 2007 model, 135000 km on clock, with engine 2nz-fe 1nz-fe is neither vvt or vvt-i is a plain engine without O2 sensor but has variable resistor so I have no help from internet except www.toyodiy.com website which gives exact engine details, components attached along with part numbers once you insert frame no of your car on site.


    (
    03/2007 TOYOTA COROLLA (NZE120R-GEMDKP) )

    OBD test on this vehicle does not provides information related to Long Term Fuel Trim LTFT and Short term fuel trim STFT cross checked on my OBD device and that?s from Toyata Rawal Motors, Toyata GT motors so how do I determine the air to fuel mixture of this EFI car as they say that computer they have from company does not shows LTFT,STFT on this vehicle.


    PROBLEM TAG:


    Car starts well on cold start up on petrol, but stalls if we press accelerator in morning while engine is cold while on petrol. Anyway once switched to CNG then flies but after 5 minutes once temperature has reached its optimum temperature then car runs well even on petrol.


    PROBLEM TAG:

    Vehicle stumbles on cold startup if accelerated but no problem while idling.

    PROBLEM TAG:

    Car stalls on petrol once accelerated from cold startup but becomes ok once attained proper operating temperature.

    Problem is a year old problem, guess what I have tried and done numbers of times

    Fuel Pump:
    Changed with denso original

    Fuel Filter:
    Changed twice with Toyata genuine fuel filter twice in last 15000km.

    Fuel Pressure Regulator:
    changed twice in last 15000 km.

    Fuel Pressure Test:
    Nobody had fuel gauge so had to buy my own. Fuel pressure is 42PSI once clicked and does not drops below 36psi even after 5 minutes. Mechanic says that let is try to install kabli and let?s see and I am sick and tired of everyone guessing, spending my money and still no results.

    Injectors ultrasonic cleaning:
    done from Nazir autos some 7000km back, injectors were fine but were cleaned again. Since then I regulator disconnect the injectors and keep on cleaning with carburetor cleaner at times and again expecting a magic to take place. I have disconnected individual injectors several time once car is idling and it stalls indicating that fuel injectors are firing properly.

    Ignition Coils:
    although, car runs perfectly well on CNG but ignition coils were disconnected while car was idling. It stalled and showed all of them to be ok both on petrol and CNG.

    Spark Plugs:
    sick and tired of changing them, adjusting the clearance and cleaning it after every 500km. this has became a joke.

    Tappet settings and valve clearance:
    Checked before twice and again checked today. Verified to be ok and within specs.

    Trouble Codes:
    car does not gives any trouble code.

    Throttle body wash:
    throttle body cleaned, idle control valve adjusted and it seems to work fine as once its position is changed then either idle rpm increase or decreases. Throttle position sensor works ok as obd test reveals that it is changing its position once we hit accelerator.

    MAF sensor:
    it gives flow of air and also provides intake air temperature. I have bought a second hand from scrap yard, switched its position but data on both the sensors matches 100%. Toyata motors have also tried to install a new one as a smart mechanic highlighted a problem with his blind fate, changed it but problem was intact so he took it back declaring the original to be ok.

    Intake Manifold:
    recently, I started suspecting that intake manifold maybe blocked but once it was removed then it seemed clear, slightly dirty but nothing such that can block the air passage. Cleaned and was installed back but problem is intact.

    Coolant Temperature Sensor:
    suspecting that it may be a problem so I looked at its reading on EML327 once car is started. It starts from 20 C and goes all the way to 92 C and now that I look at it every time once car starts. Although, I can change this but will I keep on spending money as results looks ok.

    Intake Temperature Sensor:
    this reading varies from 55 F to 70 F depending upon the temperature and sensor comes within the MAF sensor. It has been replaced with other MAF sensor I have but OBD shows same consistent readings on both the sensors so have attached it back.

    Air Filter and Housing blockage:
    it has no blockage like people do it on CNG cars. Clear air passage, no obstructing in between. Seems fine to me , as I take it off and put it back every time. Clean it as well.

    PCV valve:
    You know this is for Engine ventilation, removed and cleaned, seems ok as air passes one way and installed back. No improvement.

    Knock Sensor:
    Today, I got it opened, although did not had any trouble code from ECU. It seemed perfectly clean from inside so got it installed again without disturbing anything.

    Variable Resistor:
    this controls the air to fuel mixture, increases supply of petrol and has a specific procedure for increasing or decreasing the petrol. But you know what, I visited toyata GT motors, Toyata motors as they did not had the specific equipment to test and adjust it. So blindly said that problem is not with this part. Manual says that it not be disturbed or adjusted without measuring the CO2 content from exhaust.

    Fuel Tank inspection:
    fuel tank opened, checked and seems ok and crystal clear.

    Engine Condition: throws water droplets out on cold startup in morning from exhaust, mechanic says that its a sign that engine is in good condition, oil changes after every 5k, diary maintained, no signs of sludge so far. rocks on cng.

    I don?t know, I have got nut, Every mechanic wants to repeat older steps, once satisfied that they are ok, then says ?I don?t know?. Even toyata mechanic says ? temporarily tries to satisfy me, charges and next day problem is back. Don?t have so much time that I keep running around a shitty reason, they keep charging me and problems remains intact.

    Kindly help me solve the puzzle as I keep on repeating previous steps. If problem is known, I can repair it but here I don?t know what is an issue.

    That trim pot does not act like an o2 sensor replacement but more of an AFR sensor replacement but only for idle mixture. Its a pretty simple device to work out, but for 90% correction (100% is not possible as its a fixed unit) you need an EG analyser to work with it, make sure when you use such EG analyser your engine oil is not a cheap variety as it can upset the EG content - specially when checking an EFI engine EG.

    Imagine it as a base setting and off idle response setting.

    dont try to measure it with a multimeter on V, its useless - the only way to see it working is to test on resistance scale.

    Its Called Variable resistor..Its Not Any Kind Of sensor......Usually Called Trim POT

    VAF Sensor Is Something Else....Don't Know About Ur Desi Pashtoo terms.....!!

Somehow VAF (signal wire) was not showing any voltage once I took the measurement with respect to battery?s ground as document says that Voltage is suppose to vary between 0-5Volts. While car was idling, I removed the sensor expecting a response but nothing happened, not even a engine check light like it does not matter if sensor is there or not. Again, I tried to measure the Voltage between VAF and battery?s positive and this time it turned out to be 13.30 Volts against 14.20V between battery?s terminal. Then being curious, I started to turn the variable resistor towards R and did not notice even a slight change in Voltage either with respect to battery?s positive and still showed zero w.r.t battery?s negative. Document describes values for correct resistances but here it seemed completely out of aspects and in hundreds.

    I think, I will need to buy this sensor from scrap yard, maybe problem is that this part is not working at all and further need to test everything again and verify my observations.

    Simply Disconnect The Sensor Reset ECU And Check....!!

    CEL Might Appear But Problem Should Resolve If Its The Culprit...

    B.t.w Measure The Resistance In OHM's Between terminals.....1-2 And In Kilo Ohms Between 2-3

    Thanking you so much atta brother, finally I have been able to resolve the issue. It?s surprising, that I highlighted this to many people including the lead mechanic at many Toyata motors but they flatly refused that problem be with variable resistor even-though I told him that?s the only thing which is left and being suspected but he insisted on working on parts which already been verified. I have searched everywhere, but found no answers, help or clue. I wonder, how many mechanics must have ripped the poor owners on same vehicle as I find none who even had a clue to this and I already spent a lot on same things over and over again.

    I was able to remove the variable resistor, find 5 volts adopter for powering the sensor, first measured the resistances which turned out to as follow while comparing it with document, I suspected the problem until I connected it with 5volts adopter.

    http://www.moranbahweather.com/toyota/lc_trj12/rm/rm1151e/m_05_0187.pdf


    VC to E2: 4.52k Ohms as compared to range of 3.5 to 6.5 Ohms as prescribed in manual
    E2 to VAF: 1.02 k Ohm as compared to range of 0 Ohm to 5kOhm
    VC to VAF: 3.6 k Ohm, range not prescribed

    But once, I connected it with 5 Volts adopter then voltage varied from 0 to 4.55 Volts so knew that the part to be good. Voltage decreases once moved towards R and increased once moved towards L. Found the initial value on resistor to be 0.8 Volts but adjusted to 2 Volts and modified the wirings for testing on car and once connected the problem was already gone and car was rocking. Information, you provided on phone was very helpful such as that it comes from factory with preset value at 1.23 Volts and adjustment to 5% per 50,000km so later, started decreasing the voltage till I brought it to 1.3 Volts as found the RPM to be more stable on this and near to that with CNG. Took the car on drive, able to climb up on a hilly road, stop in-between and still able to move without even a slight hesitations and these were the things I never imaged doing before on petrol, now such tremendous power this car had.

    I will further test the vehicle and will keep you informed regarding its status. I hope, you will enjoy the pictures I have taken while testing this, a big thanks to you and a way of hope to others facing similar issue.

    Sorry, I just read your message, resistance on this variable resistor was completely out of specs as compared to given on document found on net. Maximum voltage it read was 4.55 Volts while minimum was 0. There were two labels on resistors “R”, “L”, I guess R points towards Rich and L towards Lean. But once screw was turned towards “R” then voltage decreased and once towards “L” it increased. I was expecting the opposite but since eventually ECU was interested in Volts it receives so does not matter what the internal mechanism be. I guess, if maximum Voltage registered was 4.55V as compared to 5Volts then internal mechanism of resistor must have deteriorated that’s why I must be experiencing this issue. I will again test this in terms of variation in resistance.

    Any other way, I can tune this without having access to exhaust analyzer or any known value you think is best suited in absence of this equipment. Too much petrol is also an issue as compared to more swear in terms of lean condition.

Today, once I checked it then it was at 0.9 Volts. Yesterday, I was trying to be careful with original wirings but today in-order to be sure before disposing the part, I had to cut the wires to detach the sensor completely along with grip. Honestly, If I had moved the variable resistor towards R yesterday then tried to move the same amount back to its original position. <!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false"

    this never goes bad unless it was flooded with water which shorts it out. Ideally you dont want the mix to be too lean to prevent valve seat problems.

Since the engine temperature is low at cold start up, the configured settings either inject excessive fuel or less fuel. Good luck

    Is applicable in all these engines, if your car has and you have cross checked tappet settings, injectors, ignition coils, connectivity between coils and engine, connectivity between injectors and engine, fuel pressures to be ok,, inlet temperature sensor and coolant temperature be fine then go for this simple DIY.

    I don't remember that I ever touched this unit before. unfortunate I guess but I had been avoiding petrol as plugs would go dirty very soon that’s why been trying to drive it on cng mostly . I hope, driving on CNG must have avoided valve seals from going bad, can’t say further but hope they be good. I was recently scared as hell, as now my dad drives this car, CNG about to shutdown and nothing I do would fix the issue and feared how would I rescue him if car went bad as he is old now.

    i showed my car to many gud mechanics but no solution at all... everyone told me its normal in winter season ur car is perfectly fine
    so do update us if u find any cure to this problem !!
    P.S : my car is running on petrol from December 2012 no CNG after that !!
    i guess, we got a cure now.

    This Is Actually The Last Thing People Think Can Go Wrong....!!

    And Flooding It With Water Is Easy JOB.....Just Service It Once And You Are Good To GO...!

    Any other way, I can tune this without having access to exhaust analyzer or any known value you think is best suited in absence of this equipment. Too much petrol is also an issue as compared to more swear in terms of lean condition.

    BEST Is To Use AFR Sensor To Know Exactly Where You Stand.....BEside These Readings So Many Things Matter Also SO AFR's Can't Be Read Until Unless You Have AFR Sensor....!

    Once You Have It COnnected....You Know Exact Correction Needed To Be Done...Else Its Just Shooting BLIND In Dark...
