DTC P0342 [MZR-CD (RF Turbo)]

BME010200300W11

DTC P0342 | CMP sensor circuit low input
--- | ---
DETECTION CONDITION | • PCM monitors input signal from CMP sensor while engine is running. If input signal from CMP sensor is not input at 12 crankshaft revolutions, PCM determines CMP sensor circuit low input.
POSSIBLE CAUSE | • CMP sensor malfunction • Connector or terminal malfunction • Short to GND in wiring between CMP sensor terminal A and PCM terminal 81 • Short to GND in wiring between CMP sensor terminal B and PCM terminal 55 • Open circuit in wiring between CMP sensor terminal A and PCM terminal 81
• Open circuit in wiring between CMP sensor terminal B and PCM terminal 55
• PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to next step.
No | Go to next step.
2 | INSPECT POOR CONNECTION OF CMP SENSOR CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to Step 7.
No | Go to next step.
3 | INSPECT CMP SENSOR CIRCUIT FOR SHORT TO GND • Turn engine switch to OFF. • Inspect continuity between following harnesses:

  - CMP sensor terminal A and body GND.
  - CMP sensor terminal B and body GND.

• Is there continuity?
Yes
Repair or replace harness for short to GND, go to Step 7.
No | Go to next step.
4 | INSPECT CMP SENSOR • Inspect CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace CMP sensor, go to Step 7. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to next step.
5 | INSPECT POOR CONNECTION OF PCM CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to Step 7.
No | Go to next step.
6 | INSPECT CMP SENSOR CIRCUIT FOR OPEN • Turn engine switch to OFF. • Inspect continuity between following harnesses:

  - CMP sensor terminal A and PCM terminal 81.
  - CMP sensor terminal B and PCM terminal 55.

• Is there continuity?
Yes
Go to next step.
No | Repair or replace harness for open, go to next step.
7 | VERIFY TROUBLESHOOTING OF DTC P0342 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from PCM memory using WDS or equivalent. • Start engine. • Is same DTC present? | Yes | Replace PCM, go to next step. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Is there any DTC present? | Yes | Go to applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
