P0137 CEL Code

P0137 O2 Sensor Circuit Range/Performance Problem - Low Input (Bank 1 Sensor 2). My friend got this code pulled, he has a Bosal DP, Catback, and Stage 2 Utec and thats it, plus the mil elim installed. anyone know what this would be, its not the cat inefficency code.

no its not the EGT is an O2 sensor. If it was an egt code, it would be the egt sensor. It is a problem mechanically with the rear o2. It has nothing to do with the cat inffeciency. Kanos, if you or your friend are familiar with a voltmeter, i can give you directions on how to inspect it.

Edit: just saw your friend has the MIL eliminator installed. I will look at my factory manual when i get home. (at work right now)

yeah I have a volt meter, my guess is a wire came loose under the car where we spliced it.

My friend re-wired the Mil Elim. and his went away. I really don't know much else about the code. Sucks to hear you are still getting one even after replacing the mil elim.
