DTC P2122:00: Notes
DTC P2122:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P2122:00 |
APP sensor No. 1 circuit low input |
| DETECTION CONDITION |
- The PCM monitors the APP sensor No. 1 signal. If the PCM detects that the APP sensor No. 1 voltage is below 0.12 V
, the PCM determines that the APP sensor No. 1 circuit has a malfunction.
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
- Short to ground in wiring harness between the following terminals:
- APP sensor terminal A-PCM terminal 1Q
- APP sensor terminal B-PCM terminal 1Y
- 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 1Q
- APP sensor terminal B-PCM terminal 1Y
- APP sensor No. 1 malfunction
- PCM malfunction
