| DETECTION CONDITION |
- The PCM monitors the input voltage from APP sensor No. 2. If the input voltage at the PCM terminal 2AR is less than 0.1 V, the PCM determines that the APP sensor No. 2 circuit has a malfunction.
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/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 F-PCM terminal 2AC
- APP sensor terminal E-PCM terminal 2AR
- PCM connector or terminals malfunction
- APP sensor No. 2 signal circuit and ground circuit are shorted to each other
- Open circuit in wiring harness between the following terminals:
- APP sensor terminal F-PCM terminal 2AC
- APP sensor terminal E-PCM terminal 2AR
- APP sensor No. 2 malfunction
- PCM malfunction
