Code P0103 2015 Chevrolet Silverado Description
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 greater than 14, 500 Hz (about 1233 g/s) for greater than 10 s.
What are the Possible Causes of the DTC P0103 2015 Chevrolet Silverado?
- 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 DTC P0103 2015 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
