DTC P0102: Notes

DTC P0102 [L3] CHART

DTC P0102	MAF sensor circuit low Input
DETECTION CONDITION	The PCM monitors input voltage from the MAF sensor when the engine running. If the input voltage at PCM terminal 1AC is below 0.21 V , the PCM determines that the MAF circuit has malfunction. Diagnostic support note This is a continuous monitor (CCM). MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA is available. DTC is stored in the PCM memory.
POSSIBLE CAUSE	MAF sensor malfunction Connector or terminal malfunction Short to ground in wiring harness between MAF/IAT sensor terminal C and PCM terminal 1 AC Open circuit in wiring harness between MAF/IAT sensor terminal C and PCM terminal 1AC Open circuit in wiring harness between main relay and MAF/IAT sensor terminal A PCM malfunction
