So I was driving down the highway today cruising normally and all of a sudden my CEL pops on and I was like, eh, probably just the DR mod comin back to the ECU again and throwin the code.

I decided for sh**s and giggles that I would stop by Autozone on the way home just to be sure that was what was causing the CEL.

Autozone guy plugs in the OBDII and I see "Code 1 of 4" come up, and of course the first thing that came to my head was "WTF?" So, he scans through and up comes P0137, 0138, and 0139 (DAMN!T).

Long story short, I can't really pinpoint what the cause of this situation would be, but I guess that means it is about that time to run some O2 sims. Anyone who has experience with this problem, any help would be appreciated. Thanks.

 

Wow... those are all codes for your bank 1 sensor 2 pretty much...

From what I recall from the FSM, the possible causes are injectors, fuel pressure, harnesses/connectors, or heated O2 sensor... maybe intake air leak too....

 

Interesting......I know I have a leak coming from the front manifold of the stock ypipe (long story, dont ask) but I wouldn't have expected that to foul the O2 sensor. At least it sounds like all the codes are coming from one faulty sensor and not three separate ones.

 

Hit me up on AIM if I'm online later today and I"ll send ya the 01 FSM for reference...

 

i have the 0138 code for the 02 sensor.

 

its your 02, ive had those codes for about a year now, and the CEL light comes and goes randomly

 

hey puppetmaster...do u have the FSM for an 02?

or anybody else on here have the FSM for an 02?
