DESCRIPTION



DTC No. DTC Detection Condition Trouble Area
P0335 Crankshaft position sensor signals are not received even though camshaft position sensor signals for 1 revolution are received (3 trip detection logic).

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • Crankshaft (sensor plate)

  • ECM
P0336

Either of the following condition is met (3 trip detection logic):


  • 2 missing teeth position of crank angle sensor plate cannot be detected.

  • Position of teeth cannot be detected correctly.

  • Abnormal crankshaft position sensor signal pattern detected by crankshaft position sensor signal monitor IC*1.

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • Crankshaft (sensor plate)

  • ECM

Note

If any DTCs related to the crankshaft position sensor, throttle position sensor and accelerator pedal sensor assembly are output simultaneously, inspect the VC circuit of each component.

Tech Tips


  • DTC P0335 is detected when the engine cranks 16 revolutions or more.

  • DTC P0336 is detected when the engine cranks 20 revolutions or more.

Tech Tips


  • If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.

  • The engine speed can be checked by using the GTS. To perform the check, follow the procedures below:


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.

      The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.

  • If the voltage output of the crankshaft position sensor is insufficient, the engine speed is indicated as lower than the actual engine rpm.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. READ VALUE USING GTS (ENGINE SPEED)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.

    5. Start the engine.

    6. Read the values displayed on the GTS while the engine is running.

      OK
      Correct values are displayed.

      Tech Tips


      • To check the engine speed change, display the graph on the GTS.

      • If the engine does not start, check the engine speed while cranking.

      • If the engine speed indicated on the GTS remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.
