What does the MAF code p0102 mean?
What does the MAF code p0102 mean?
What Does Code P0102 Mean? Your MAF sensor is typically installed downstream from your air filter on your air intake tract. It measures both the density and volume of air passing through your intake and into the engine. A P0102 error code means that there’s insufficient air traveling through your air filter.
What does the DTC code p0102 stand for?
Diagnostic trouble code (DTC) P0102 stands for “Mass Air Flow (MAF) Circuit Low.” The code is set when the powertrain control module (PCM)—your car’s primary computer—perceives a problem with the mass airflow (MAF) sensor’s performance.
What causes OBD-II scanner error code p0102?
A vacuum leak will allow air to escape instead of being drawn into your engine. Repair or replace the necessary tract or components to create a firm seal. Once you restore your air intake system, reset the code and check again to see if you’ve solved the OBD-II scanner error code P0102 problem.
Is there a one size fits all fix for p0102?
There is no one-size-fits-all answer to a P0102 code, or any other codes, for that matter—but once you’ve properly diagnosed the issue, you should be able to find the right fix with the help of reputable online automotive guides.
What does the p0102 diagnostic trouble code mean?
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.
Can a bad MAF sensor cause a p0102 error?
Code P0102 isn’t always caused by a bad MAF sensor. There are other factors that may come into play with this specific error code. But don’t be alarmed—there are a lot of resources out there that can help you diagnose and manage this error code. Here are some videos that will help you understand and properly perform a diagnosis:
What causes a Chevy Silverado to get p0102?
Here are the most common causes of P0102 in the Chevy Silverado. They are presented loosely in order from most to least likely: MAF Sensor Dirty – Over the course of its life, the MAF sensor will often get so covered in grime that it’ll no longer get an accurate reading.
What are the codes for mass air flow?
Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation. Closely related MAF circuit trouble codes include P0100, P0101, P0103, and P0104. Photo of a MAF sensor:
