|What are the Possible Causes of the Code P0102 Oldsmobile?
Dirty Air Filter
Dirty Mass Air Flow (MAF) Sensor
Intake air leaks
Faulty Mass Air Flow Sensor
Mass Air Flow Sensor harness is open or shorted
Mass Air Flow Sensor circuit poor electrical connection
|How to Fix the P0102 Oldsmobile Code?
Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Before replacing the Mass Air Flow (MAF) Sensor, try replacing the air filter and cleaning the Mass Air Flow Sensor with low compress air or Mass Air Flow Sensor Cleaner. Reset code and drive vehicle. If the code comes back, you must replace the Mass Air Flow Sensor to fix the problem.
|What is the Cost to Diagnose the Code P0102 Oldsmobile?
The cost to diagnose the P0102 Oldsmobile code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|What are Code P0102 Oldsmobile Possible Symptoms?
Engine Light ON (or Service Engine Soon Warning Light)
Engine running rough
Excessive fuel consumption
|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.
