Both these lights came on yesterday on the drive home (45 miles) I normally drive with the TRAC OFF but, ever since the check engine light came on, I can't switch from Off to On.

I have not yet taken it to get the codes read.

any clues/pointers?

Most probably it´s your 02 sensor. Try to disconnect the battery and after a few seconds connect it again. That would solve the problem ´til next time it shows up.
Mine goes on after rainy days or long trips. It´s not an expensive part btw.

How do I check the codes myself? Autozone and Advance Auto Parts cannot check anything older than a '96. Or am I better off taking it to a dealer?

check codes first of all---te1 and e1 with paper clip------------sometimes the trac light comes on with the cel----idk why it just does.

good luck

traction control works in combo of your abs and by reducing engine power from reducing the amount of air your throttle body allows into the intake.

since you dont have an abs light on aswell, i would assume its something to do with the IAC or something in the area.. who knows.. see what codes you pull..

It´s easier to take the negative off the battery. 2 minutes of work! Try that please.

Five bucks its your 02 sensors, just went through the same scenario. Let me know if thats what it is.. Most likely the front ones.

25: Air–Fuel Ratio Lean Malfunction

Here are some pictures from the book if you are still having issues with your trac/abs etc.

I picked up an O2 sensor today. We'll see if that helps at all.

MMCtuner

Strange, when the o2 sensor is faulty the air/fuel mixture is rich instead of lean.
Hopefully that´ll work. 1uz-fe?

groverwood

yes. I believe so.

didn't get to the o2 sensor yet. hopefully tonight.

MMCtuner

Any news? Did the o2 sensor arrive?

groverwood

it's here. haven't had time to put in in yet.

work+kids+baseball=not much free time. I'd like to get at it this weekend.

Mine just went off today-CEL with flashing Trac light. This has happened to me before and it was indeed a sensor. I can't remember if it was mass air flow or an O2 sensor now, it was a couple years ago. I'll go see if I can dig up my bill from the garage.
