My SES light came on a few days ago on my 2002 Z28. The codes were for my skip shift solenoid, reverse solenoid, and MAF sensor code P0120 I believe. I replaced the MAF first because that is causing my car to run rough and erased the codes. The same codes came back up and the car still runs like crap. Anybody have any idea on what it can be besides the MAF since I already waisted all the money on that part?

Thanks.

 

Have you messed with the plugins on the trans lately? If not, is there a possibility that you ran over something that could have snagged the wires. The skip shift and the reverse soleniod both plug in on the drivers side of the trans.

 

No I haven't messed with the trans lately but I did hit a raccoon so it might of messed up the wires down there. I will check it out later when I have a chance. First I need to figure out whats wrong with the MAF because that is causing my car to run rough. The 3 codes I got were:

P0102 MAF low frequency
P0801 reverse solenoid
P0803 Skip Shift solenoid

The thing is I had my SS programed out when I had my car dyno tuned. My car has LT's, true duels, and cammed.

 

Check your "ENG SEN" fuse and see if it's blown. The MAF, 02's, skip shift and reverse lockout solenoid are all on the same circuit. If it's blown first thing I'd look for is an 02 harness burnt/hitting against your LTs somewhere - happened to a friend of mine.

 

Thanks man for the advice. You were dead on with that fuse being blown. The wiring that was messed up was my skip shift wiring. I got ripped off when i hit a raccoon and then grounded out. It sucks that I spent the $200 on the MAF before I figured out the real problem but oh well. Thanks again.

 

Try selling the MAF - lots of people descreen it and find out they don't like how the car runs without it.
