Obd Ii Codes P1505,p1507

[jrindiana]

I Am Getting Obd Ii Codes P1505 And P1507 Dealing With The Idle Air Control Valve Having Low Voltage When Open And Closed I Tried Cleaning It With Throttle Body Cleaner, And Cleaned The Pluge To It With Electronics Cleaner, But Had No Luck So I Am Wanting To Know If I More Than Likely Need To Replace This Part.


Thanks

If cleaning it doesnt help, check the wires if you can see if they look freyed. I would just replace the unit tho myself.

The codes are related to an electrical failure of the ISC/IAC or a bad connection - a sticky valve does not generate any codes.

Check the resistance of the ISC two windings and check that it is buzzing with the ignition turned on.

and i have checked the wiring looks fine, and also chcked the pluge with a test light and it is producing power, when the car is running it idles rough with the iac conected but when i un pluge it the idle smooths out i can only see it being bab maybe the electronics of the iac not getting enough power to perform right

thanks for you info on the matter and futher info will be great

thanks
