Ok guys, I have a problem. I recently purchased a 2000 Pontiac Trans am with the LS1 engine. I am new to these cars. I recently had the check engine light come on. I ran the code and it came back as MAF voltage low. I bought a used MAF sensor off ebay thinking that the MAF was bad. I installed the new MAF sensor reset the computer, and the code came back on a few seconds later. I then called my buddy who drives a 99 camaro ls1 and tried his MAF on my car, reset the computer, and the code came on. I used my old MAF sensor on his car, and his car did not throw any codes. I was wondering if anyone can help me out. I checked the wiring to the MAF and it looks fine. What should I do next? Thanks in advance

ok thanks. I just checked the fuses inside the engine compartment. I noticed that the engine senor fuse was blown. I replaced it with a "20" fuse. As soon as I started the engine, the fuse popped. I tried another fuse, and the same thing happened. What can be causing the problem? WHere can I start to look? Thanks again

Get your Multimeter out and disconnect the battery and then the main pcm connectors and go from the pcm to those ckts listed and don't be afraid to pull, twist, and gnaw on those wires with your favorite beaver.
