96 LT4 -P0100 Mass Airflow Code - MAF Sensor Fine
Trying to figure this out, seriously scratching my head.
1996 LT4 car, getting a check engine light the split second you start the car up, always immediate code upon startup even after clearing with scan tool. Code is P0100 Mass Airflow Sensor. I swapped the MAF out with a good one from a Camaro and still have the same problem. I'm getting 12 volts to the pink wire and 5 volts to the white wire just like it's supposed to work.
I began to think "MAF Sensor RELAY" but am finding there is no MAF Sensor Relay on a 96 model.......... ??? Wires look good, connector looks good.
Any ideas ?

Also maybe the PCM?
Check your fsm for the diagram and you can check continuity between the PCM connector and MAF sensor too.
