What does this engine light code mean and how do I repair it?
P0102 Powertrain
Mass or Volume Air Flow Circuit Low Input
|
OBD-II Trouble Code: P0102 Mass Air Flow (MAF) Circuit Low Input
looks like your maf is bad, or maybe the wires leading to the plug for the maf are cracked or missing insulation. you can also try cleaning your maf with maf cleaner.
It means there is something wrong with the mass air flow circuit. You need to check the wiring and if the wiring is ok replace the sensor.
I just got a code "P0420" "Catalyst System Efficiency Below Threshold Bank 1" Does anyone know what this actually means? Thanks
means that your catalitic converter isn't doing its job.
