If it is one of the O2 sensors, I have no clue which one is and is the Bosh O2 good? The car is only 22000 miles thats what surprises me.

Any input will be welcome..!

You can look up DTC codes at www.obdii.com Are you sure it's P1131, and not P1133?

 

Thanks for the input.
The code is correct.

I didn't see in which way the "AutoTap" web site can help me, because the link (www.obdii.com) goes straight to AutoTap people. What I saw there was too much text and less real info for specifique real problems.

The tuning had been done 8 month ago. Program used was LS1Edit.

The problem just start recentely.

AutoZone scanned it. They got "P1131 = Lack of HO2S Switch - Sensor Indicates Lean"

 

That refers to the after cat sensor on the driver's side.

 

I agree with 2001NBMZ28. Are you sure that the code is not 1133. I don't believe that there is a 1131 code. A 1133 code is HO2S Insufficient Switching Bank 1 Sensor 1. (Drivers side). Check the code again. It has to be 1133.

 

The reason I questioned the code was because when I looked it up on www.obdii.com/codes.asp it didn't look like an Fbody code - 1131 Circuit Low Varience B1, S2 (Engine C) only entry. One or two different numbers can make the difference between banks/sensors - just want you to identify the right one before replacing what might be the wrong sensor.

 

agreed, 1131 is not a f-body code
