![]() ![]() ![]() Repair low voltage, electrical short or wiring harness.Here are a few of the possible repairs you could be looking at: Otherwise, you could be throwing money at something that won’t resolve the issue. 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. Contaminated or dirty mass air flow sensor.Electrical short or defective wiring harness.However, it’s not uncommon to deal with some sort of leak or electrical short as well. Most of the issues surrounding the P0102 trouble code have to do with the MAF sensor itself or the connection to it. 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? ![]()
