Put a new rear O2 sensor and it fixed it. Only problem you might have is if you have an aftermarket downpipe. If it is Catless then you are going to need some type of tune, opensource, Cobb AP, etc.... Even if it is a high flow cat then you will still need a tune because it will throw a code 75% of the time. If your stock cat is still on then replace your rear O2 sensor and that should fix it. Could be something else but mine was the exact same problem.

I have an 08 Saturn Astra XR. It won't come out of 1st. Throwing code p2096 post catalyst fuel trim system too lean bank 1. Put on new o2 sensor on both streams and I cleaned out mass air flow. Help?


That code wouldn't cause it not to come out of first gear . How did you retrieve this code P2096 , code reader etc.. This is an invalid code , not listed in Saturn service information . Have DTC'S check by a GM dealer , Chevy . You obviously have a transmission problem not an O2 sensor problem . Some code readers will replace a code with an other if it doesn't have the right one . Software .

What does code p2096 mean for 2005 magnum SE?


P2096- Post Catalyst Fuel Trim Sys Too Lean Bank1... It could be the result of bad gas or if you used fuel with a higher content of Ethanol. It could also mean that the post cat. converter O2 sensor on the driver side is bad. I would try filling up with a good quality gas (minimal Ethanol content), disconnect the negative terminal on the battery for a minute or so to reset the MAL (malfunction indicator light) and see if that takes care of it. If the code reappears, you may have a bad sensor, maybe ECU ECM PCM, worst case.... If you happen to need any info or ECU ECM PCM for this current vehicle (as they have a HIGH failure rate) or ANY other type of Car, diesel trucks small and big, SUV DIESELs ANYTHING etc, please call 888-672-4816 or 954-279-2040 and tell them Tim From FIXYA.COM sent you for FREE PROGRAMMING on YOUR NEW ECU ECM PCM DIESEL OR GAS COMPUTER!! Best Regards, -Tim

Hi there:
DTC P2096 - Post Catalyst Fuel Trim System Too Lean (Bank 1)

Lean mixture code could be caused by a leakage in the rubber boot that is between the throttle body (similar to a carburetor) and the air cleaner housing. Following are all the tests to be done for a vehicle other than yours... HERE.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2004 or 05 Jeep Wrangler dtc P2096 (Post catalyst fuel trim bank 1 to lean). It set the mil lamp and then reset it self. Pulled the code with a scanner and found 1 of 2 to be P2096 and 2of 2 to be P2096...


Here is more information about P2096
P2096-DOWN STREAM FUEL TRIM LEAN BANK 1

WHEN MONITORED 
With the engine running in closed loop mode, the ambient/battery temperature above (-7°C) 20°F , altitude below 8500 ft and fuel level greater than 15%.

SET CONDITION 
If the PCM multiplies short term compensation by long term adaptive and a certain percentage is exceeded for two trips, a freeze frame is stored, the MIL illuminates and a trouble code is stored. Two Trip Fault. Three good trips to turn off the MIL.

Here are some possible casuses:
Exhaust leak
Engine mechanical problem
02 sensor
02 signal circut
02 return circut
Fuel contamination

Good luck and hope this helps.
