2023年1月7日 · What Does the P0102 Code Mean? The P0102 code is set when the Powertrain Control Module (PCM) detects that the mass air flow (MAF) sensor frequency signal isn’t performing in the normal expected range set by the manufacturer. This trouble code indicates that there’s a low condition within the mass air flow sensor or circuit.

2022年8月22日 · How can I diagnose the OBDII code P0102 on my Chevrolet? - You can diagnose the code by inspecting the MAF sensor for dirt or debris, checking the air filter for clogs, inspecting the intake system for leaks, and using a scan tool to monitor MAF sensor data.

2010年7月12日 · In this test tutorial, I'll show you how to test the mass air flow sensor to see if it's bad (and lighting up the check engine light) or not. This MAF test is done in 3 easy steps.

2018年11月2日 · There are several potential causes of the P0102 code, including a faulty or contaminated MAF sensor, debris blocking the air flow sensor element, vacuum leaks, a poorly closed air filter box, or an incorrect air filter installed.

2024年10月16日 · Code P0102 indicates that the engine control module or powertrain control module has detected low voltage in the mass air flow (MAF) sensor, which can affect the normal air-fuel ratio. A dirty or defective MAF sensor usually causes a P0102 code.

2020年7月24日 · In a nutshell, a P0102: MAF Sensor Circuit Low Frequency tells you that the MAF sensor is stuck producing a low frequency signal. In this tutorial, I'll go into detail what this trouble code means -all in plain English. I'll also talk about some of the tests you can perform to find its cause and solution. What Does Trouble Code P0102 Mean?

A trouble code P0102 is triggered when there is low airflow registered by the Mass Air Flow, or MAF, sensor. When this happens, you need to know how do I fix trouble code P0102? First, learn more about your MAF sensor, inspect your vehicle for typical symptoms and look for common causes in order to find the right solution.

2021年7月11日 · In many GM vehicles, the code P0102 is caused by a faulty mass air flow sensor. The repair involves clearing the code and replacing the MAF sensor if no other problems are found. In some Mazda vehicles with the Skyactiv engine, the code P0102 could be caused by a failed mass air flow sensor.

2022年8月22日 · Repair Information for P0102 Chevrolet code. Learn what Mass or Volume Air Flow Circuit Low Input means, location and how to repair?

This P0102 diagnostic trouble code (DTC) means that there is a low condition detected in the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value.
