Read the new codes and get freeze frame data.Take the vehicle for a test drive and see what codes set.Clear all of the trouble codes from the system.These are the same methods used by certified mechanics when the P0102 trouble code is set in the computer. If you want to diagnose P0102 like the professionals do, you would follow the steps we outline.
#P0102 CHEVY SILVERADO HOW TO#
This part is very sensitive and you can easily damage it, so do it very carefully and don’t touch it! How to Diagnose the P0102 Trouble Code If it has dirt or corrosion on it, a simple clean up should do the trick. To clean the MAF sensor, remove it and carefully clean the sensor head with some electrical cleaner or a special MAF sensor cleaner and let it dry. It’s also possible the MAF sensor simply needs to be cleaned. While the code indicates something is wrong with the MAF sensor, it could be reading faulty because of other conditions. The most common mistake is to replace the MAF sensor without first determining that it is the problem.

It’s important to complete a full diagnostics check before deciding what needs to be repaired. Otherwise, you could allow further damage to be done as the engine isn’t running in optimal condition. After all, you don’t want to get stranded somewhere.Įither way, the code should be repaired as soon as possible. If the fault causes you to struggle starting the engine, you may have a more pressing concern. You might also notice reduced fuel economy and a rough operation. In general, it might cause some minor drivability concerns or no symptoms other than the Check Engine Light. Low – Usually the P0102 trouble code isn’t stopping you from getting anywhere.
#P0102 CHEVY SILVERADO DRIVERS#
Here are the most common symptoms that drivers endure: While no other symptoms may occur, there could be performance issues that arise, indicating that something isn’t right. The most common symptom of P0102 is a Check Engine Light. The P0102 can often be seen together with the P0100, P0101, P0103 or P0104 trouble codes as they are closely related to the MAF sensor. If the input or output signal isn’t right or it’s low for a specified amount of time, this code will set.
When it’s working as intended, the MAF sends out a signal used by the engine control module to determine how much fuel is needed to mix with the air entering the combustion chamber. This code sets if the ECM or PCM determines there’s a problem with the performance of the mass airflow sensor, which is found between the throttle body and air filter. The P0102 code indicates that the mass airflow (MAF) circuit is reading low voltage. P0102 – Mass or Volume Air Flow Circuit Low Input What Does the P0102 Code Mean?
