Code No. P0341: Camshaft Position Sensor Range/Performance Problem


OPERATION



  • Refer to Code No. P0340: Camshaft Position Sensor System .

FUNCTION



  • The camshaft position sensor detects the top dead center on the compression stroke of the No. 1 cylinder and inputs a pulse signal to the engine-ECU.

TROUBLE JUDGMENT


Check Conditions
  • Battery positive voltage is 6 - 16 V.
  • Engine speed is 350 r/min or more.
Judgment Criterion
  • The number of output pulses from the camshaft position sensor every two engine rotations (from when one excessive tooth is detected to when another is detected) is not five.

PROBABLE CAUSES



  • Failed camshaft position sensor
  • Open/short circuit in camshaft position sensor circuit or loose connector contact
  • Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Installation check of camshaft position sensor

  • Check whether the camshaft position sensor is correctly installed.

Q. Is the check result normal?
Go to Step 2 .
Repair or replace the camshaft position sensor.

STEP 2. M.U.T.-III diagnosis code

  • Reconfirmation of diagnosis code.

Q. Is the diagnosis code set?
Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - How to Perform Chassis Number Writing ). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
