Code No. P0336: Crank Angle Sensor Range/Performance Problem


OPERATION



  • Refer to Code No. P0335: Crank Angle Sensor System .

FUNCTION



  • The crank angle sensor detects the crank angle (position) and inputs a pulse signal to the engine-ECU.
  • In response to the signal, the engine-ECU detects the engine speed, controls the fuel injection timing and fuel injection quantity, etc

TROUBLE JUDGMENT


Check Conditions
  • Battery positive voltage is 6 - 16 V.
  • Engine speed is 350 r/min or more
Judgment Criterion
  • The number of pulses from the crank shaft position sensor per engine rotation is abnormal.

PROBABLE CAUSES



  • Failed crank angle sensor
  • Open/short circuit in crank angle sensor circuit or loose connector contact
  • Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Installation check of crank angle sensor



  • Check whether the crank angle sensor is correctly installed.

Q. Is the check result normal?
Go to Step 2.
Repair or replace the crank angle 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 - Precautions Before Service - 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 ). After registering the injector identification code, the vehicle equipped with the DPF carries out the forcible DPF regeneration. (Refer to GROUP 17 - Emission Control - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
