| DETECTION CONDITION |
- If the PCM detects the TP sensor No. 1 voltage is to be above 4.85 V
, PCM determines that the TP sensor No. 1 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 (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Regulates the upper limit of the APP sensor output.
|
| POSSIBLE CAUSE |
- Throttle body connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between throttle body terminal A and PCM terminal 2AK
- TP sensor No. 1 power supply circuit and signal circuit are shorted to each other
- Open circuit in wiring harness between the following terminals:
- Throttle body terminal A-PCM terminal 2AK
- Throttle body terminal D-PCM terminal 2AN
- TP sensor No. 1 malfunction
- PCM malfunction
