Trouble code P1509 means: IAC System High RPM
Replace Idle Air Control Valve (IAC)
By TechToolTime:
I must disagree, no codes actually say "replace a component" , they only indicate which circuit is out of parameters. In the case of an IAC fault , it can often be a matter of cleaning the build up carbon / coke in the throttle body and iac passages. A toothbrush and some lacquer thinner / carb cleaner will do wonders. It's also a code that might set for a vacuum leak that's causing a high idle.
The check engine light would illuminate and the code(s) would point to one or more of the O2 sensors.
It has many solenoids. Need to know which one you are referring to.
O2 sensors are always screewed into the EXHAUST system. Look at the exhaust from the engine alway back to the muffler and you will find them.
What sensors? Be specific.
