P0102 on Pontiac
Mass or Volume Air Flow Sensor Circuit Low Input
P0102 on Pontiac vehicles indicates mass or volume air flow sensor circuit low input. Au7o has documented this code across 1 Pontiac model — most commonly on Bonneville. P0102 is a generic OBD-II code meaning the engine computer detected an abnormally low voltage or signal from the Mass Air Flow (MAF) sensor circuit. The MAF sensor measures how much air is entering the engine so the computer can deliver the correct amount of fuel. A low signal tells the computer it is reading less airflow than is actually present, which can cause poor running, stalling, or reduced power. While not usually an emergency, it can affect drivability and fuel economy and should be addressed. Typical repair costs on Pontiac range from $100 to $350, depending on the specific model and root cause.
Common Causes of P0102
- •Dirty or contaminated MAF sensor element
- •Faulty MAF sensor
- •Damaged, corroded, or loose MAF connector/wiring
- •Open or short to ground in the signal or power circuit
- •Dirty or restricted air filter / intake blockage
- •Vacuum or intake air leak after the sensor
- •Poor power or ground supply to the sensor

- Mass Air Flow (MAF) Sensor Contamination and Failure1996-2005
The MAF sensor on OBD-II 3800-powered Bonnevilles is a frequent failure point: its hot-wire element becomes contaminated with dirt or oil (often from over-oiled aftermarket filters) or the sensor electronics fail outright, sending a low or erratic frequency signal to the PCM and setting codes P0101/P0102. The result is hesitation, stumbling, rough idle, lack of power, and stalling. A classic 3800 diagnostic trick — the engine running noticeably better with the MAF unplugged — confirms the sensor as the culprit.
