Question about 1995 Volkswagen Jetta

1 Answer

My 1997 honda cr-v has had a problem with idle air control valve for a long time.the code is 14-1 idle air control valve-circuit failure.i replaced the idle switch yet the the light still comes on and the vehicle stalls in the morning before it behaves normally.two auto electricians have suggested replacing the ics in the computer since its not sending the correct voltage to the idle air control valve.is this helpful or just another non-working theory?

P0508 code on 2001 Honda CR-V how do I troubleshoot


Hello,

P0508 = Idle Air Control System Circuit Low

Symptoms:
Engine Light ON (or Service Engine Soon Warning Light) - Engine hard to start - Rough or erratic idle speed.

Causes:
Dirty throttle body - Electric throttle control actuator misadjusted or damaged - Faulty Electric throttle control actuator - Intake air leak - Poor electrical connection to the Intake Air Control (IAC) valve.

Solution:
If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.


I hope this helps!

I still have the problem with my 1997 honda cr-v .the diagnostic code is 14-01 - IAC -circuit failure.i have replaced the idle air control valve and it wont go.the idling is erratic and it starts and...


1)is the IAC new or used?
2)did you clean the IAC's air passages in the throttle body? sometimes those carbon deposits can be significant. shoot throttle body cleaner in there until most of the black is off
3)the IAC circuit is completely bypassed during acceleration because of air passage through the main throttle flap, therefore it is normal that acceleration is unaffected in spite of a problem in the IAC circuit
