Clean the FITV if the engine has one.

Check for vacuum and intake air leaks.

CEL codes?

Any CEL?

When you turn the key to ON, does the Check Engine Light...

1. Turn on then go off.

2. Turn on and stay on.

3. Does NOT turn on at all.

 

2. Turn on and stay on.

 

Jump service connector to pull codes.

 

i found a video on internet explain how to know the error number on my engine
so when i did it i receive error no.6 and error no.19 and error no.14 when i look for those error
i found that error no.14 idle air control valve or bad ECM i change the idle but
nothing changed so i guess i have a problem in my ECM

any idea friends

 

Code 6 is a problem in the ECT sensor circuit. This code, like code 14, can cause an idle problem.

Reset the ECU to see whether either code returns after running engine or driving car.
