Code P0102 2014 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 less than 850 Hz (about 1.43 g/s) for greater than 10 s.
What are the Possible Causes of the DTC P0102 2014 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 P0102 2014 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.

Frequently Asked Questions about P0102 2014 Chevrolet Silverado Code
1. What does the OBDII code P0102 mean for a 2014 Chevrolet Silverado?
P0102 indicates the Mass Air Flow (MAF) sensor is reporting a low voltage signal, suggesting insufficient airflow measurement to the engine control module.
2. What are common symptoms of P0102 on a 2014 Chevy Silverado?
Symptoms include reduced engine performance, rough idling, poor fuel economy, hesitation during acceleration, and in some cases, the engine may stall.
3. What causes the P0102 code in a 2014 Chevrolet Silverado?
Common causes include a dirty or faulty MAF sensor, damaged wiring or connectors, air leaks in the intake system, or a clogged air filter.
4. Can a dirty air filter trigger the P0102 code?
Yes, a clogged air filter can restrict airflow to the MAF sensor, causing it to report a low input and potentially trigger the P0102 code.
5. How do I fix the P0102 code on a 2014 Chevy Silverado?
Start by cleaning or replacing the MAF sensor, inspecting and repairing damaged wiring or connectors, checking for intake system leaks, and replacing the air filter if necessary.
6. Can I drive my 2014 Silverado with a P0102 code?
While the vehicle may still run, driving with a P0102 code can lead to decreased performance, poor fuel efficiency, and potential damage to the engine over time.
7. How do I clean the MAF sensor to resolve the P0102 code?
Use a designated MAF sensor cleaner to gently clean the sensor without touching the delicate wires, then allow it to dry completely before reinstalling.
8. Will replacing the MAF sensor automatically fix the P0102 code?
Not necessarily; if the issue lies in wiring, connectors, or air intake leaks, replacing the sensor alone may not resolve the code.
9. How much does it cost to fix the P0102 code on a 2014 Chevrolet Silverado?
Costs vary, but cleaning the MAF sensor or replacing an air filter is inexpensive, while replacing the MAF sensor may cost $100-$400 depending on parts and labor.
10. Can a vacuum leak cause the P0102 code in a 2014 Chevy Silverado?
Yes, a vacuum leak can disrupt airflow measurement to the MAF sensor, leading to the low input signal associated with the P0102 code.
