Lambda Probe Errors
Hi Everyone!
I've finally got all of the misfires taken care of in my car. Now, i'm having a couple of strange "lambda probe" faults. From what i can tell this is the O2 sensors. I'm not sure how to test this to see if my sensors need to be replaced. Here are my fault codes: 2C7E - 2C7E Lambda probe behind catalytic converter, trimming control 2C2B - 2C2B Lambda probe in front of catalytic converter, system check 2C7F - 2C7F Lambda probe behind catalytic converter 2, trimm control The car generally drives very smoothly, although at WOT i get just a tiny bit of shaking. Car idles great and under normal driving i can barely tell the difference. I've done absolutely nothing to the car except Jb4. completely stock. I checked vaccum lines and no leak. I'm not sure what else to check at this point. Any suggestions please let me know! |
