DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate and a pickup coil. The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of an iron core and magnet. The sensor plate rotates and as each tooth passes through the pickup coil, a pulse signal is created. The pickup coil generates 34 signals for each engine revolution. Based on these signals, the ECM calculates the crankshaft position and engine RPM. Using these calculations, the common rail system is controlled.

INSPECTION PROCEDURE

Note:

After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).

Tip:

  • If no trouble is found in the diagnostic troubleshooting procedure of DTC P0335, troubleshoot the engine mechanical system.

  • Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.

    INSPECT CRANKSHAFT POSITION SENSOR


    1. A01BI20E29

      Disconnect the D17 sensor connector.

    2. Measure the resistance of the sensor.

      Standard resistance
      Tester Connection Condition Specified Condition
      1 - 2 Cold 1,630 to 2,740 Ω
      1 - 2 Hot 2,065 to 3,225 Ω
      Tip:

      In the table above, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10° to 50°C (14° to 122°F). "Hot" means approximately 50° to 100°C (122° to 212°F).

    CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)


    1. A01BDKME19

      Disconnect the D17 sensor connector.

    2. Disconnect the D1 ECM connector.

    3. Measure the resistance of the wire harness side connectors.

      Standard resistance
      Tester Connection Specified Condition
      D17-1 (NE) - D1-27 (NE+) Below 1 Ω
      D17-2 (NE-) - D1-34 (NE-) Below 1 Ω
      D17-1 (NE) or D1-27 (NE+) - Body ground 10 kΩ or higher
      D17-2 (NE-) or D1-34 (NE-) - Body ground 10 kΩ or higher
