DTC P2122 [L3]: Notes
DTC P2122 (L3) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P2122 |
Accelerator pedal position (APP) sensor No.1 circuit low input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is less than 0.12 V, the PCM determines that the APP sensor No.1 circuit input voltage is low.
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.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- APP sensor connector or terminal malfunction
- Short to ground in wiring harness between APP sensor terminal A and PCM terminal 1AL
- Short to ground in wiring harness between APP sensor terminal B and PCM terminal 1AP
- APP sensor No.1 malfunction
- PCM connector or terminal malfunction
- Open circuit in wiring harness between APP sensor terminal A and PCM terminal 1AL
- Open circuit in wiring harness between APP sensor terminal B and PCM terminal 1AP
- PCM malfunction
