| DTC P2122:00 |
APP sensor No. 1 circuit low input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from APP sensor No. 1. If the input voltage at the PCM terminal 2AN is less than 0.1 V
, the PCM determines that the APP sensor No. 1 circuit input voltage is low.
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.
- DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Regulates the upper limit of the APP sensor output.
|
| POSSIBLE CAUSE |
- APP sensor connector or terminals malfunction
- Short to ground in wiring harness between the following terminals:
- APP sensor terminal A-PCM terminal 2AR
- APP sensor terminal B-PCM terminal 2AN
- PCM connector or terminals malfunction
- APP sensor No. 1 signal circuit and ground circuit are shorted to each other
- Open circuit in wiring harness between the following terminals:
- APP sensor terminal A-PCM terminal 2AR
- APP sensor terminal B-PCM terminal 2AN
- APP sensor No. 1 malfunction
- PCM malfunction
