So my check engine light came on.....

I went to help my sister move out of her apartment and on the way home my check engine light came on. I checked the gauges and everything was cool so I waited to run my DTCs on my ol' hypercrap. Well I run the codes and four come up. C0265, P0101,P0327,P0332. Well im familiar with the "P" codes because P0327 and P0332 are Knock sensor errors *again*

and the P0101 is a mass air sensor error. Which now that I think about it has posted intermittently in the past 4 years (maybe 2-3 times) and it will go away.

Well when I replaced the rear knock sensor (only the rear

) last year money was tight and I needed to get it done (which is why I only replaced one). Now either the front one has gone out or the wiring harness has gone out. So I will be replacing both the front sensor and the harness this time. Do any of you know if I can get the harness from any place (AutoZone, discount, etc) or do I have to go to the dealership

? Also what is the C0265 code? I seen it may have to do with the ABS system (I know the ABS module is out due to the brake and abs lights are always on but its never thrown a code). Any one know about that one?

So by that do you mean that you have pulled the fuse out for the EBCM?

The code C0265 sets for the ebcm control relay circut malfunction.

Things to check: 60 Amp Maxi fuse in underhood fuse block, blown fuse = this code
Seeing how you are down in florida I doubt this could be the problem but check the grounds connected at the body mount under the drivers door, they like to rust and also sets this code

To check the rest of the system disconnect the large connector at the EBCM motor that has the red and black wires, there are two connectors, you need to test the one on the upper side near the inside of the frame rail. connect test leads to the MODULE side of that and turn the key on. test light should light up, if not needs a new EBCM.

Let me know how you make out and if I can answer any more questions
