P0037 keeps coming back on me. I reset the ECU just as Cobb's instructions say, start the car and it is gone. Next time i go to drive the car it is back. I dont know why it is doing this. It has happend about 10 times now. I have the rear 02 sensor uplugged..Should i just plug it back in? Any help would be great..Thanks!

mm...

Maybe the sensor is bad?



Check the wires and stuff too, those have been known to wear.

Well, i thought that the AP would clear that one..i could be wrong. Should it be plugged in then. I have the sensor in the dp but dont have the connectors plugged to each other. I was under the impression that it should be left unplugged and zip tied out of the way of the driveshaft. I am running an invidia dp and bosal cb. Thanks!

I figured it out..I bought my AP used and i just realized it doesnt have the latest map revisions loaded on it..I went to Cobbs website and found that the P0037 code delete is new to the 1.30 version. I will load the new ones tonight and hopefully it will be gone! Thanks for the help though.

yes the newest versions should eliminate that code, you don't even need the sensor plugged in.
