DTC P0341:00 [MZR-CD 2.2]

id0102f3154900

DTC P0341:00

CMP sensor range/performance problem
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 the CMP sensor performance malfunction.
MONITORING CONDITIONS
―  Battery voltage: 8—20 V
―  Engine speed: 700 rpm or more
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 first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  CMP sensor connector or terminals malfunction
•  Loose CMP sensor installation bolt
•  CMP sensor malfunction
•  Related wiring harness malfunction
•  CMP sensor pulse wheel malfunction
•  PCM connector or terminals malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service 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 INPUT SIGNAL STATUS IS CONCERN INTERMITTENT OR CONSTANT
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
•  Perform the “INTERMITTENT CONCERN TROUBLESHOOTING” procedure.
4
INSPECT CMP SENSOR CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the CMP sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 10.
No
Go to the next step.
5
VERIFY CMP SENSOR INSTALLATION CONDITION
•  Verify the CMP sensor installation.
•  Is the CMP sensor installed securely?
Yes
Go to the next step.
No
Retighten the CMP sensor installation bolt, then go to Step 10.
(See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
6
INSPECT CMP SENSOR
•  Inspect the CMP sensor.
•  Is there any malfunction?
Yes
Replace the CMP sensor, then go to Step 10.
(See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
No
Go to the next step.
7
INSPECT CMP SENSOR HARNESS
•  Inspect the CMP sensor related wiring harness condition (intermittent open or short).
•  Is there any malfunction?
Yes
Repair or replace the suspected wiring harness, then go to Step 10.
No
Go to the next step.
8
INSPECT CMP SENSOR PULSE WHEEL
•  Inspect the CMP sensor pulse wheel.
•  Is there any malfunction?
Yes
Replace the intake side camshaft assembly, then go to Step 10.
(See CYLINDER HEAD GASKET REPLACEMENT [MZR-CD 2.2].)
No
Go to the next step.
9
INSPECT PCM CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to the next step.
No
Go to the next step.
10
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
No
DTC troubleshooting completed.
