DTC P2128:00: APP sensor No.2 circuit high input: Notes

DTC DETECTION CONDITION & POSSIBLE CAUSES

DTC P2128:00	APP sensor No.2 circuit high input
DETECTION CONDITION	If the input voltage is 4.8 V or more  , the PCM determines that the APP sensor No.2 circuit input voltage is high. Diagnostic support note  This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	APP sensor connector or terminals malfunction PCM connector or terminals malfunction Short to power supply in wiring harness between APP sensor terminal C and PCM terminal 1 AD APP sensor No.2 power supply circuit and signal circuit are shorted to each other Open circuit in wiring harness between APP sensor terminal B and PCM terminal 1C APP sensor No.2 malfunction PCM malfunction
