Longtubes installed, Question regarding rear 02s.

Since I have disabled the rear 02 sensors via Predator, why cant I just put plugs in and hold 02 sensors in my toolbox ?

BTW- I had 2 DTC codes, Sensor 1 Bank1 and Sensor 1 Bank 2. I know I have the drivers side 02 plugged in to the correct place but Im doubting that I plugged the passengers side 02 into the right plug. Can anybody help or gimme a picture of which goes into which ?


Thanks
John

 

Last I tried, I still got a CEL with the rear O2 sensors disabled. Not sure if Diablo has corrected that or not. I went with a B&G stage II and have not had a CEL since.

 

:hmm:

 

I would suggest PMing Mike at Diablo and posing the question to him.

 

Gonna Drive the Jeep to work today, I will see if the light come on and write down the codes. Before I get on the horn/keyboard, I wanna verify that the codes I have are the rear sensors. Darrin, I know I plugged the front drivers 02 into the same plug. I plugged the Passengers side 02 into the plug that faces forward, is that the correct plug ? I might have the other 2 sensors crossed but that shouldnt matter since they are suppose to be turned off. If anybody has pictures of the way the sensors plug into the harness above trans that would help. :gotpics::thanks:

 

Tell Dave to disable the sensors in your CMR tune.

 

The latest CROM update (according to Mike) will fix any issues of not being able to disable the rear 02's, check and make sure you have the most recent update first there have been 2 in the last week or so

 

Just got here, I have a PO138 Code and something about a high voltage code. Can somebody verify these are the rear 02s ? Im going to be in class all day but will try and PM Mike.

Thanks

 

P0138 is: 1/2 O2 sensor shorted to voltage

 

P0138/P0158 codes are fixed in the latest revision, or if running a custom tune have your tuner get in touch with me and I will tell them the proper way to disable the codes in CMR. (Quoting Mike from 3/10/08) I think your gonna be all fixed up soon I want to see you run tomorrow night or Sat.

 

Me too, get that biotch fixed.

 

Modern Horsepower is working on a new tune for NA and N20. I will test them on the Dyno tomorrow afternoon to verify air fuel and then head to the track. :good: I did exchange PMs with Mike and he said the new code will fix the PO138 and PO158 codes.
