P0102 Error Messages MAF Sensor has been replaced - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a Cammed 2010 Camaro SS. I have driven it for about 7000 Trouble Free Miles in the year that I have had it. It suddenly started popping and hesitating randomly. It does not appear to be dependent on load. It is getting a P0102 Error. I checked all of the wiring and the connector. I replaced the MAF Sensor with a new GM one. I cleared the codes and they came back right away. Any ideas? The MAF Fuse is not blown. Thank you

1. Check for 12 volt power to the MAF on the Pink wire. KOEO

2. Check for ground on the Black/White wire.

3. Key on, sensor disconnected, check for 5 volts on the Yellow wire coming from the Engine Control Module.

4. Wiggle the connector at the sensor to see if you can make the reading on the scanner come and go.

The Yellow wire should produce a 0-5 volt square wave signal back probing the wire with the engine running.
Expect between 2,000–3,900 Hz, depending on the Engine Coolant Temperature (ECT).

Thank you. I haven't had time to look at it but will tomorrow. I put different Wanted Ads for PDF or Printed Service Manuals

It might be worth it to get an alldata subscription. I think they have the oem trouble shooting steps.
