![]() This is because the MAF sensor is responsible for measuring the amount of air entering the engine, and if it is not functioning properly, the engine may not receive enough air to run. Stalling: In some cases, a P0102 code can cause your Silverado to stall or even refuse to start.You may notice that your Silverado is not as responsive as it used to be or that it takes longer to accelerate than it should. Hesitation: Another symptom of a faulty MAF sensor is hesitation or stumbling during acceleration.A dirty or faulty MAF sensor can cause the engine to run poorly at idle. Rough Idle: If your Silverado is idling roughly, it may be a sign that there is an issue with the mass air flow (MAF) sensor.This light will come on to indicate that there is a problem with your vehicle’s emissions system. Check Engine Light: The most obvious sign of a P0102 code is the illumination of the Check Engine Light on your truck’s dashboard.Here are some of the most common symptoms associated with a P0102 code: If your Chevy Silverado is experiencing a P0102 trouble code, you may notice a variety of symptoms. Ignoring the P0102 code can lead to more serious engine problems down the line, so it’s important to address it as soon as possible. If you are unsure how to proceed, it’s always best to take your Chevy Silverado to a qualified mechanic who can diagnose and fix the issue for you. This may involve cleaning or replacing your Silverado’s MAF sensor, checking for air leaks, or repairing any electrical shorts. To diagnose and fix this issue, you will need to start by checking the possible causes listed below. This can cause a variety of issues, including reduced fuel economy, trouble starting the engine, and poor engine performance. Specifically, the voltage value is lower than the expected range. When the MAF circuit is low, it means that the sensor is not performing within its specified operating range. The MAF is one of the most important sensors your Silverado has. The PCM (Powertrain Control Module) uses this data to adjust the air fuel mixture. Your Silverado’s MAF sensor is responsible for metering the air as it enters the engine. P0102: MAF Sensor – Circuit Low Voltage Input MAF Sensor A typical MAF Sensor P0102 Code Meaning and Definition Definition However, it’s not uncommon to deal with some sort of leak or electrical short as well. The most common causes of the P0102 code are related to the MAF sensor itself or the connection to it. If you encounter this code, it is important to diagnose and fix the problem promptly to avoid further damage to your truck. 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. When this happens, your truck may experience drivability issues such as stalling, lack of power, rough idle, and hesitation. This code indicates that the Mass Air Flow (MAF) circuit is low and not performing within its specified operating range. If you own a Chevy Silverado, you may have encountered the P0102 trouble code.
