Does anyone know a site where i could find a list trouble codes from a 1992 F-150 302 V8. I got a (539) whatever that is

Thanks,
Brandon

 

fordfuelinjection.com has a complete list of codes.

539 is "A/C or Defroster ON during KOEO test". So, assuming you had the A/C or defroster on when you ran the test, you don't really have a problem. Rerun the test with all accessories off and see what you get.

 

DTC 539
A/C or defrost "ON" during Self-Test.

Was a/c off when you did it?

 

i test it again its 53 NOt 539 sorry

53 says the tps voltage is too high. Check the tps sensor electrically to see if it is indeed faulty. A Haynes manual will have the procedure.

 

THANKS you

 

I thought all '92-95 OBDI codes were 3 digits.
