Crankshaft Position Sensor "A" Circuit Intermittent

DESCRIPTION

The crankshaft position sensor system consists of a crank angle sensor plate and a pickup coil. The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of wound copper wire, an iron core and a 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 per engine rotation. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the fuel injection timing and ignition timing are controlled.

DTC No.

    Condition

    Idling with warm engine

MONITOR DESCRIPTION

If there is no signal from the crankshaft position sensor despite the engine revolving, the ECM interprets this as a malfunction of the sensor.

If the malfunction is not repaired successfully, a DTC is stored 10 seconds after the engine is next started.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR ).
  4. Turn the ignition switch off and wait for at least 30 seconds.
  5. Turn the ignition switch to ON and turn the Techstream on.
  6. Start the engine.
  7. Idle the engine for 20 seconds or more [A].
  8. Enter the following menus: Powertrain / Engine / Trouble Codes [B].
  9. Read pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  11. Input the DTC: P0335 or P0339.
  12. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    If the judgment result shows INCOMPLETE or N/A, perform steps [A] through [B] again.

  13. If no pending DTC is output, perform a universal trip and check for permanent DTCs (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR ).

    HINT:

    • If a permanent DTC is output, the system is malfunctioning.
    • If no permanent DTC is output, the system is normal.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

HINT:

After performing the inspection procedure for the crankshaft position sensor, if DTC P0335 is output again, check the following items related to the camshaft position sensor.

  • Installation condition of the VVT sensor
  • Installation condition of the camshaft
  • Connection of the VVT sensor connector

HINT:

  • If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
  • Check the engine speed. The engine speed can be checked using the Techstream. Follow the procedure below:
    1. Connect the Techstream to the DLC3.
    2. Start the engine.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
    • The engine speed may be indicated as zero despite the engine rotating 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.
  • Read freeze frame data using the Techstream. 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 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

HINT:

  • To check the engine speed change, display the graph on the Techstream.
  • If the engine does not start, check the engine speed while cranking.
  • If the engine speed indicated on the Techstream remains zero (0), there may be an open or short in the crankshaft position sensor circuit.
