I've got a "P1509 manufacturer specific" Check engine code. Autozone could not tell me what it was and the dealer's service manager said that they couldn't tell without hooking the diagnostic computer to it.
Please refer me to where i might find it.

The PC/ED manual doesn't show a P1509. You sure that's really the code they pulled?

 

Yes. I had it read at autozone. It was in the memory twice but also listed under the code "manufacturer specific".

 

I've looked in a few different years and I cant find a P1509 anywhere. Any symptoms of a problem?

 

I apologize, my dyslexia is acting up. It's a 1506, Idle Air control
overspeed. New Idle Air control module. I'm going install it now.
Sorry, but thank you anyway.
