Code P0102 2016 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 2016 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

Frequently Asked Questions about P0102 2016 Chevrolet Silverado Code
1. What does the P0102 code mean on a 2016 Chevrolet Silverado?
The P0102 code indicates a "Mass or Volume Air Flow Circuit Low Input," meaning the MAF sensor is detecting airflow levels below the expected range.
2. What are the common symptoms of a P0102 code on a 2016 Silverado?
Symptoms may include poor fuel economy, rough idling, lack of power, stalling, or the Check Engine Light being illuminated.
3. What causes the P0102 code on a 2016 Chevrolet Silverado?
Common causes include a dirty or faulty MAF sensor, air intake leaks, clogged air filters, damaged wiring or connectors, or a faulty PCM.
4. Can a dirty air filter cause the P0102 code?
Yes, a clogged or dirty air filter can restrict airflow, causing the MAF sensor to send low input signals and trigger the P0102 code.
5. How do I fix the P0102 code on my 2016 Silverado?
Start by cleaning or replacing the MAF sensor, inspecting the air intake system for leaks or clogs, checking the wiring and connectors, and replacing the air filter if it's dirty.
6. Can I drive my Silverado with a P0102 code?
Driving with a P0102 code is possible but not recommended, as it can lead to poor performance, reduced fuel efficiency, and potential engine damage over time.
7. How do I clean the MAF sensor on a 2016 Chevrolet Silverado?
Use a MAF sensor cleaner spray, carefully remove the sensor, and spray the cleaner onto the sensor element without touching it. Allow it to dry completely before reinstalling.
8. Will resetting the Check Engine Light fix the P0102 code?
Resetting the light may temporarily clear the code, but it won’t fix the underlying issue. The code will likely return until the root cause is addressed.
9. How much does it cost to repair a P0102 code on a 2016 Silverado?
Costs vary depending on the issue, ranging from $10-$30 for a new air filter, $20-$50 for MAF sensor cleaner, to $100-$300 for a replacement MAF sensor.
10. Can a vacuum leak cause the P0102 code?
Yes, a vacuum leak can disrupt airflow readings, leading to a low input signal from the MAF sensor and triggering the P0102 code.
