    Is this issue being shown on the OBD device you purchased or the error is showing on the meter?
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    In my opinion these devices are crap, Try to visit a good toyota workshop or another good workshop who have latest scanning devices, Get your car scanned if they give your car a clean chit stay happy.

    Dont worry too much. On googling i guess the error code is related to the oxygen sensor.

    And the whistling sound your refering too is from the cylincer springs, Conventional cars have rubber boots in the cylincer piping Vitz has springs, Which either need to be replaced or oiled to let the whistling sound go away.

    Next time you hear the sound, go and put a foot on your car cylincer. It will go away.

    oops, you got this code from ELM - so this a generic OBD2 code which for Toyota means knock control malfunction.

    and is very vague.

    Get your vehicle tested on a proper scantool to see whats happening.

    Today I have go to Toyota Central Motors and asked to scan my car they say Scanning the car on Toyota device price is 16000 which they don't give any guaranteed the problem will fix so i think its not worth it because they don't give any surety So i leave from Toyota workshop

    Karachi PW Members do you know any good mechanics who can able to scan or diagnose Error Code problem?

    I have heard few mechanics name but don't know they provide scanning service

    They quoted you 16,000 for a scan alone?

    Are you serious!!!

    Simply get your cars throttle body cleaned, Plugs fixed and get all oil renewed. For a simple tune up goto PSO near ayesha masjid the (ganja guy tuning wala) he should be helpful. He is a nice fellow. Just be sure to keep your eyes open and be with the car at all times.


    One more thing, Dont google too much, Google isnt always right, It can mostly take you in the wrong direction.

    Toyota has a standard charges for Scanning and Diagnose related problems This charges is included of scanning and diagnose if any issue appear its solved that issue but they can't guaranteed that issue will resolved Completely So i think its not worth that price they are asking and price is too much high....

    Due to this i have purchase my own Standard OBD2 scanner and found 2 error codes P1603 and P1605 but still can't find the exact fault

    Bro, did the Check Engine lights remains On now ?
    Pending codes mean that some error has occured once in the ECU which it has stored but that error is not pertaining now, so no need to worry for the past errors, if there is something really wrong with the car, the error will appear again in the form of Check Engine Light glowing, then you can connect the device again to check the error code.

    Let me clear my scenario My car has experiencing some issue when AC is ON and car is in low RPM when i applied brakes on it there is some kind of choking sound coming from engine bay and then my car is stopped in middle of the road and check engine light appear and then when i start my car immediately it takes longer self and car don't start after waiting for 1 to 2 mins then i start my car again it start fine without longer self and check engine light don't appear after engine started. This issue is very hard to find the exact cause when this appear on what case so i can describe this to Toyota Dealership because they can't diagnose that problem and they said if it occurs in their presence then they could figure it out whats the issue.

    Currently Check Engine light, Oil light and battery light appear and don't remove after few seconds when i start my car self and engine is not started. Once i start my car engine these light is removed.

    When I purchase the OBD2 device so i can diagnose the above mentioned problem so i came up 2 error codes P1603 and P1605 and i remove the error code from App in ECU and then i drove my car then few weeks the same problem happen again and when i diagnose the error code i found out same error code appear which i was previously clear through App.

    I found out P1605 is Pending Error Code but P1603 is fault error code as per my knowledge.

    chinyoti has given me some advice so i will go it on weekend.

    Also Xulfiqar has been given me some advice on these error code on other post as well. You can refer below post

    Yes as per advice of Chinyoti, you should visit and get your car checked properly.
    As the error codes have appeared again after clearing, so it means there must be some issue with the car.

    Default Dtc p1605

    Error Code P1605 (Knock control error)

    The possible reason of appearing this code.
    first the behaviours of car to be checked
    -the car is idling poor
    -the car is giving feel of as if one of the cylinder is not working properly in lower RPMs
    -Speed limits to 80-90km.

    if these are the symptoms then you must check the VVT sensor or we can also call it OCV(Oil control Sensor).
    this error appears because once the oil change is over due. the carbon in oil cause the tiny pours in this sensor blocked the proper oil circulation is not there. Just open the OCV Sensor get it washed by solvent (diesel/petrol) and fix it back clear the DTC and drive your car and i hope the same error will not appear any more.

    Must give your feedback if you find this tip useful.Toyota Vitz Error Code P1605  Help required -1697786
