Cel 125

[doodie]

Got my CEL pulled and came out to be 125, its not the O2 sensor, its something about the coolant not going into some sort of loop thing. I'm not too sure so if anyone can let me know what it really is. And what I can do to fix it?

Actually, it probably IS the O2 sensor. I just had this problem on my car. The wording for the code 125 that everyone has is NOT what it is according to the DSM manual. the actual wording in the technical manual is:

"Excessive time to enter closed loop fuel control"


I'll bet you dollars to donuts it's the O2 sensor. But just to be sure, I'll tell ya what: What does your engine temp gauge (in the car) tell you? Id the car getting hot? Is the heat real damn hot?

I will sell you my old Coolan temp sensor for 10 bux plus shipping, cuz it's about 48 bux frm the dealer (and everybody at all the parts palces, including the dealer, will try to give you one that won't fit...trust me). It works fine, my problem was the O2 sensor.

the other option is to find someone with a datalogger, or buy one yourself and save yourself some trouble with this diagnosis....and monitor the coolant temp and O2 readings...the coolant temp comes from the sensor your car is supposedly saying is bad (but probably isn't)...if it IS reading low, then OK, you need a new sensor....but if it isn't, I'll bethca your upstream O2 readings are between 0 and .01 volts.

Well, I'm not getting any bad gas millage and I'm not running rich. My temp gauge is reading fine when its fully warmed up. It says in the middle.
