Salam!My 2010 cultus efi is showing check engine light on at wide open throttle(WOT) and goes off when i release the throttle.it is happening after i had changed the gear oil and cleaned air filter.i have also reset the ecu but its still showing.. @ser_gtr and @xulfiqar i shall be greatful to you if you help me...
Gear Oil Have Nothing To Do With CEL...But Air Filter.....!! Did You Mess Around With any Sensor Around????
And Did Someone try Adjusting Your TPS Sensor Or Fiddle In Some Sense???
Any Difference In Running??? Or Its Just CEL???
sir..no body touched any sensor.just the mechanic changed the gear oil and cleaned the air filter.there is no difference in running at all.same as before...just the CEL turns on around 2000-2200 rpm and goes off when i release the throttle
Get it scanned and see what is it actually.........
That's Strange....Get It Scanned....Maybe TPS..Maybe Something ELse....!!
It is my observation mostly oil man / mechanic remove speedo meter cable or vehicle speed sensor to fill gear oil into transmission case,check vss for proper seating and connection.
no vss in cultus efi..
@ser_gtrdrove the car after about half an hour and there is no CEL now..now what is this??
Happens Sometime...Seems ANy Sensor Malfunctioning...Keep Driving And Have Eye On It....If It Appears AGain...Get It Diagnosed..
^^^drove the car for about 10km and there is no CEL now.shukar Allah ka
Do a ecu reset by taking of the battery terminal. Most of the time reset helps
@ser_gtr and @xulfiqarits happening again.one thing i have noticed that when i open the fuel tank cover and install it again,the problem rectifies for some time and and happens again after some time...
one thing more happens only when engine is hot
Get It Scanned....No Wonder All Symptoms Are Strange....Fuel Tank COver???..:-!
Get It Scanned And CHeck Live Readings Of ALl Sensors And See WHere Its Messing...!
Are you in lahore? If you are, then try magic motors, they seemed to have better knowledge and understanding of data from sensors, always had good experience with them
It happens with me also sometimes on motorway above 100kph. there is nothing wrong about it and mostly happens due to choke air filter.. remove air blockage for CNG as you will be running car on petrol now a days
i am in sargodha.and believe me mechanics are asking 500 rs for code reading only :S
Damn them, did you try suzuki 3s?
Rs500? Toyota 3S ask 3k :-#
there was no such problem before even above 120kph..
