DTC P2138:00: Notes

DTC P2138:00	APP sensor No. 1/No. 2 voltage correlation problem
DETECTION CONDITION	The PCM compares the input voltage from APP sensor No. 1 with the input voltage from APP sensor No. 2 when the engine is running. If the difference is more than the specification, the PCM determines that there is an APP sensor No. 1/No. 2 angle correlation problem. Diagnostic support note This is a continuous monitor (CCM). The check engine light 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.
FAIL-SAFE FUNCTION	Stops the idle air control. Stops the drive-by-wire control and sets to a throttle valve opening angle necessary for the minimum driveability.
POSSIBLE CAUSE	APP sensor connector or terminals malfunction PCM connector or terminals malfunction APP sensor No. 1 malfunction APP sensor No. 2 malfunction PCM malfunction
