DTC P0340: Notes
DTC P0340 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0340 |
CMP sensor (RH) circuit malfunction |
| DETECTION CONDITION |
- The PCM monitors input voltage from the CMP sensor (RH) when the engine is running. If the CMP sensor (RH) signal timing inferred from the CKP sensor signal has deviated, PCM determines that CMP sensor (RH) circuit has malfunction.
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.
- DTC is stored in the PCM memory.

| POSSIBLE CAUSE |
- CMP sensor (RH) malfunction
- Connector or terminal malfunction
- CMP sensor (RH) is dirty
- CMP sensor (RH) malfunction
- Short to ground circuit between CMP sensor (RH) terminal A and PCM terminal 2AD
- Short to ground circuit between CMP sensor (RH) terminal B and PCM terminal 2AE
- Short to power circuit between CMP sensor (RH) terminal A and PCM terminal 2AD
- Short to power circuit between CMP sensor (RH) terminal B and PCM terminal 2AE
- Short each harness CMP sensor (RH) terminal A and B
- Open circuit between CMP sensor (RH) terminal A and PCM terminal 2AD
- Open circuit between CMP sensor (RH) terminal B and PCM terminal 2AE
- Timing chain or improper valve timing
- Loose timing chain or improper valve timing
- Loose camshaft sprocket lock bolt
- Loose crankshaft pulley lock bolt
- PCM malfunction
