swap d16z6 for d15b i used all my 1.6 equip.,ecu(p28)intake ,exaust,dist.,iat,iac. now cel code 10,14. what went wrong? runs ok,no idle problem execpt the cel. thanks.

 

code 10 is the IAT (intake air temperature) sensor - defective circuit or unplugged / defective sensor
code 14 is the IACV (Idle air control valve) - defective circuit or unplugged / defective sensor

 

removed and cleaned iacv,replaced by diff.iacv,reset ecu same code 14.iat, waiting for the new sensor.my main concern is code 14 iacv. thanks for helping: do i need a diff ecu ?(p08) iam using p28. engine dealer told me i can used p28 with no problem because im using all my equip except the engine jdm d15b.

 

you're using the JDM D15B right?
if so then it should all work fine
although, i think there might have been something different in the JDM engine regarding sensors. not sure though. but since you're using your z6 intake mani and the same ecu it shouldn't make a difference anyway. i'm stumped on this one
ronj might be able to help, he's great at solving CEL issues

 

Did you clear up the code 10? Work on that first, it almost has to be the sensor itself or the wiring.

If the idle speed is wrong and out of control for whatever reason, not necessarily the IACV itself, you get a code 14. Make susre the throttle cable is slack and not pulling the throttle open at idle. Vacuum leaks will cause it to idle too high. You may need to adjust the air bleed screw on the throttle body.
