DTC P0341 [MZR-CD (RF Turbo)]

id0102f1831200

DTC P0341 | CMP sensor range/performance malfunction
--- | ---
DETECTION CONDITION | • The PCM monitors the input signal from the CMP sensor while the engine is running. If the input signal from the CMP sensor does not correspond with the proper pulse number, the PCM determines CMP sensor performance malfunction. Diagnostic support note • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • Loose CMP sensor installation bolt • CMP sensor malfunction • Connector or terminal malfunction • CMP sensor pulse wheel malfunction • Related wiring harness malfunction • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the WDS or equivalent to the DLC-2. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE for this DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING". (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
4 | INSPECT CMP SENSOR CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Inspect for poor connection (such as damaged/pulled-out terminals, corrosion). • Is there any malfunction? | Yes | Repair or replace the suspected terminal, go to Step 10.
No | Go to the next step.
5 | INSPECT CMP SENSOR • Inspect the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace the CMP sensor, go to Step 10. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to the next step.
6 | VERIFY CMP SENSOR INSTALLATION CONDITION • Inspect for CMP sensor looseness. • Is CMP sensor loosen? | Yes | Retighten the CMP sensor installation bolt, then go to Step 10. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to the next step.
7 | INSPECT CMP SENSOR HARNESS • Inspect the CMP sensor related wiring harness condition (intermittent open or short). • Are wiring harness conditions normal? | Yes | Go to the next step.
No | Repair the suspected wiring harness, then go to Step 10.
8 | INSPECT CMP SENSOR PULSE WHEEL • Inspect the CMP sensor pulse wheel for damage and/or cracks. • Is there any malfunction? | Yes | Replace the CMP sensor pulse wheel, then go to Step 10. (See CYLINDER HEAD GASKET REPLACEMENT [MZR-CD (RF Turbo)].)
No | Go to the next step.
9 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Inspect for poor connection (such as damaged/pulled-out terminals, corrosion). • Is there any malfunction? | Yes | Repair or replace the suspected terminal, go to the next step.
No | Go to the next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0341 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE for this DTC present? | Yes | Replace the PCM, go to the next step. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the Repair Verification Drive Mode. (See OBD DRIVE MODE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
