Empowering Your Diagnosis A Comprehensive Guide to the P0102 Code

The ODBII code P0102 indicates that the Engine Control Module (ECM) has detected a low voltage signal from the Mass or Volume Air Flow (MAF) sensor "A," Just thought I would share with everyone why I was getting P0102 code ( low voltage maf sensor) and why my engine brake wouldn't work. This is a good video on how to check sensor grounds using a voltmeter. Once you get more comfortable with this type of testing, it is far more accurate than ... Mass Air Flow MAF Sensor Circuit Low Frequency (code P0102) - I'm trying to find out where the sensor actually IS on the car. The DTC P0102 appeared. I followed up and spoke with Toyota Service. They indicated that it was likely a stored code that would clear after a number of cycles. I get a "Mass or Volume Air Flow Circuit low Input" code. So I tighten all the clamps and reset the light using the obd2 scanner. As soon as I start the engine ... The 102 code means the ECM received a low voltage signal from the MAF. Low voltage means low air flow. Therefore, first try changing or cleaning the air filter. This fault indicates an issue on the MAF circuit, it could be caused by : Please find attached the P0102 diagnostic procedure. i got the code p0102 maf or vaf sensor low input circuit and it check to see if my wiring the mass air flow sensor was gettin proper voltage and ... Potential causes for this trouble code, P0102, may include: Dirty or contaminated mass air flow sensor, Failed MAF sensor, Intake air leaks.
