Hi all:
I could use a bit of advice. I have a 99 Pontiac Grand Prix with 38000 Supercharged engine. The check engine light came on with code P0102 MAF Circuit Low Input. I bench tested the MAF sensor. It varied the output voltage signal, but not by much. I purchased a new MAF sensor and bench tested it as well for comparission. It varied the voltage signal by significantly more. I thought I had found the problem. I installed the new MAF sensor. Then I disconnected the battery to clear the old code, reconnected the battery, and then started the car. The Check Engine Light is still on. What else should I be looking at? Any other advice appreciated? Thanks in advance.
