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 a APP sensor No.1/No.2 voltage correlation problem.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.
|
|
POSSIBLE CAUSE
|
• APP sensor connector or terminals malfunction
• PCM connector or terminals malfunction
• APP sensor No.1/No.2 malfunction
• PCM malfunction
