abs and trac light on a car that isnt equipped with them

Question

We have an 04 pt cruiser touring 2.4l turbo. Last week the abs and trac lights came on. next day the check engine and airbag lights came on. The airbag light went off shortly after it came on. The funny thing is that this car is not equipped with abs, there for it doesn't have trac control either. I ran engine codes and had three stored. P0508, P0032, P0038. I'm guessing the idle iac motor is causing the two o2 sensor codes. My issue is why is the abs and trac lights on?

Answer 1

P0508 IAC (idle air control ) valve circuit low

P0032  02 sensor bank 1 sensor 1 heater circuit high

P0038  02 sensor bank 1 sensor 2 heater circuit high

When the CK ENG LT comes on, for safety reason the ABS and Trac light are commanded by the ECM to turn off, You vehicle even though it does not have the option for ABS and trac it came hard wired for that option,you just have a light buld or a fuse in place where it did not need one, As for the other codes,The IAC will not cause these two codes , The 02 will cause the IAC,to be effected, but this is probable, when you get a circuit high code definiton it means there is a disconnection at that sensor or on the harness, the bad part is that it is both sensor front and rear,As for the IAC try a throttle body cleaning see if that restore the idle , if not a replacement is the solution for the IAC,
