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
  • 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 closed type DPF carries out the forcible DPF regeneration. (Refer to GROUP 17 - 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 ).
