DTC P0103:00: Notes

DTC P0103:00	MAF sensor circuit high input
DETECTION CONDITION	The PCM monitors the input voltage from the MAF sensor when the engine running. If the input voltage is above 4.9 V for 5 s , the PCM determines that the MAF circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	MAF/IAT sensor connector or terminal malfunction PCM connector or terminal malfunction Short to power supply in wiring harness between MAF/IAT sensor terminal C and PCM terminal 1AK Open circuit in wiring harness between MAF/IAT sensor terminal B and PCM terminal 1P MAF sensor malfunction PCM malfunction
