DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate and 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 a pulse signal is created as each tooth passes by the pickup coil. The pickup coil generates 34 signals for each revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the common rail injection system is controlled.

DTC Detection Drive Pattern DTC Detection Condition Trouble Area
Crank or start engine

When the following condition is met (for 5 seconds during cranking or 0.5 seconds during engine start) (1 trip detection logic):

No crankshaft position sensor signal is sent to the ECM while cranking.

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • No. 1 crankshaft position sensor plate (crankshaft)

  • ECM

No crankshaft position sensor signal is input to the ECM for 0.05 seconds or more, and conditions (a), (b) and (c) are met (1 trip detection logic):


  • (a) Engine speed is 1000 rpm or more.

  • (b) STA signal is off.

  • (c) 3 seconds or more have elapsed after STA signal is switched from on to off.

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • No. 1 crankshaft position sensor plate (crankshaft)

  • ECM

INSPECTION PROCEDURE

Note:

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

Tip:

  • Read freeze frame data using the intelligent tester. 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, and other data from the time the malfunction occurred.

  • The Data List item Engine Speed is calculated from the output of the crankshaft position sensor.

  • A DTC is also stored when the ground of a shielded wire is faulty.

    INSPECT CRANKSHAFT POSITION SENSOR


    1. A01IS6UE01

      Disconnect the crankshaft position sensor connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (NE) - 2 (NE-) Cold 835 to 1400 Ω
      1 (NE) - 2 (NE-) Hot 1060 to 1645 Ω

      (Crankshaft Position Sensor)
      Tip:

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

    3. Reconnect the crankshaft position sensor connector.

    CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)


    1. A01IRIUE07

      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 (Check for Open)
      Tester Connection Condition Specified Condition
      C24-1 (NE) - C69-103 (NE+) Always Below 1 Ω
      C24-2 (NE-) - C69-102 (NE-) Always Below 1 Ω
      C24-3 (GND) - Body ground Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      C24-1 (NE) or C69-103 (NE+) - Body ground Always 10 kΩ or higher
      C24-2 (NE-) or C69-102 (NE-) - Body ground Always 10 kΩ or higher
