DTC P0335-11: Crankshaft Position Sensor "A" Circuit Short to Ground; DTC P0335-15: Crankshaft Position Sensor "A" Circuit Short to Battery or Open [12/2019 - 10/2022]: Procedure

  1. READ VALUE USING GTS (ENGINE SPEED) 
    1. Start the engine.
    2. Read the values displayed on the GTS while the engine is running.

      Powertrain > Engine > Data List 

      Tester Display
      Engine Speed

      Standard

      Correct values are displayed.

      HINT: 

      • 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.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    CHECK FOR INTERMITTENT PROBLEMS. Refer to  CHECK FOR INTERMITTENT PROBLEMS [12/2019 - 10/2022] 

    Result: 

    NG 

    See step  2

  2. CHECK HARNESS AND CONNECTOR 
    GTY943087Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    *a Front view of wire harness connector
    (to Crankshaft Position Sensor)

    HINT: 

    Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

    1. Disconnect the crankshaft position sensor connector.
    2. Turn the ignition switch to ON.
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection Condition Specified Condition
      n7-3 (VC) - Body ground Ignition Switch ON 4.5 to 5.5 V
      n7-1 (NE+) - Body ground Ignition Switch ON 3.0 to 5.0 V
    4. Turn the ignition switch off and wait for at least 30 seconds.
    5. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      n7-3 (VC) - n7-1 (NE+) Ignition switch off 1.425 to 1.575 kΩ
      n7-2 (NE-) - Body ground Always Below 1 Ω

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE CRANK POSITION SENSOR. Refer to  REMOVAL [12/2019 - 10/2022] 

    Result: 

    NG 

    See step  3

  3. CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM) 
    1. Disconnect the crankshaft position sensor connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      n7-3 (VC) - C54-96 (VCNE) Always Below 1 Ω
      n7-2 (NE-) - C54-95 (NE-) Always Below 1 Ω
      n7-1 (NE+) - C54-128 (NE+) Always Below 1 Ω
      n7-3 (VC) or C54-96 (VCNE) - Body ground and other terminals Always 10 kΩ or higher
      n7-2 (NE-) or C54-95 (NE-) - Body ground and other terminals Always 10 kΩ or higher
      n7-1 (NE+) or C54-128 (NE+) - Body ground and other terminals Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE ECM. Refer to  REMOVAL [12/2019 - 09/2020]  , or refer to  REMOVAL [09/2020 - 10/2022] 

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR
