this answer is out of the haynes code book. code 35 idle air control valve or cicuit. Or idle speed control switch or circuit(shorted). good luck
One tip on the Idle Air system on GM's - some need to have a special reset on that part to clear the code. On the 1980-1990's GM's the procedure was to drive the car at a speed exceeding 50 mph for a minimum of five minutes, continuous. You will need to make sure the car stays above 50 for the full five minutes. Make sure to find a nice stretch of open highway where the legal speed will let you do this. This will cause the computer to push the idle air system wide open, then fully closed, to check it over the whole range. After this you can clear the codes and the code should not come back.
If it does, cleaning of the intake may help, since dirt in the passages can affect this system also.
have the cooling fans checked out.
35- idle air control (iac) valve/ circuit
Check on the driverside cylinder head. My engine code is on the head.
When the check engine light comes on it should post a code. Use a code reader to see what the code is and ask again.
and what code does the check engine light say ? go by autozone they will check it for free and get the code.
yes it can. if the check engine light shuts off by itself then chances are either the trouble code is a soft code. A hard code will keep the check engine light on until the problem is fixed and the check engine light is reset.
The check engine code PO136 means the O2 sensor circuit malfunction
It is possible that a Subaru Check Engine Code #12 is a bad starter switch. This is usually the starter relay switch malfunction code for Subaru.
You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
The check engine light sets a code for diagnostics and you need a code reader. Most auto parts stores sell code readers and most will check the codes for free.
