|What Does the P0102 Oldsmobile Code Mean?

The Mass Air Flow (MAF) sensor is integrated with the multifunction intake air sensor. The MAF sensor is an air flow meter that measures the amount of air in the sensor bore. The Engine Control Module (ECM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. A small quantity of air entering the engine indicates a deceleration or idle condition. A large quantity of air entering the engine indicates an acceleration or high load condition.
The ECM applies 5 V to the MAF sensor on the MAF sensor signal circuit. The sensor uses voltage to produce a variable frequency signal based on the inlet air flow through the sensor bore. The signal varies with engine load and is displayed by the scan tool as Hertz (Hz) and grams per second (g/s). Ignition voltage and ground circuits are also supplied to the multifunction intake air sensor internal circuits for the Intake Air Temperature (IAT) sensor 2, Humidity sensor, and MAF sensor.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAF Sensor Signal is less than 850 Hz (about 1.43 g/s) for greater than 10 s.
