Crankshaft Position Sensor Replacement

  • Tools Required

    • Ratchet
    • E10 Socket
    • Small Extension
    • Pick Tool
    • Swiveling Adapter (optional)
  • Bad Sensor Symptoms

    • Engine cranking for a long time or not starting
    • Rough idle
    • Reduced power
    • Power surging
    • P0335 Check Engine Light
  • NOTE*

    Replacing the crankshaft position sensor can be done from the engine bay, or underneath the car. Replacing it from underneath is significantly easier and faster.

  • Locate Sensor

    The crankshaft position sensor is located underneath the starter and is held in with one E10 bolt and one electrical connector.

  • Unplug Electrical Connector

    Unplug the single electric connector on the sensor by lifting up on the retention clip and pulling the connector off.

  • Remove Retention Bolt

    Remove the single E10 retention bolt.

  • NOTE*

    The best tool setup yo extract the E10 bolt in such a tight space is a ratchet with a skinny E10 socket, and short extension attached to it. A swiveling adapter can make the job easier but isn't required.

  • Remove Old Sensor

    Remove the old crankshaft position sensor by using a pick-tool or flathead screwdriver and carefully wedge it underneath the sensor while you wiggle it out of place.

  • Old Sensor Removed

    Congrats! Your old crankshaft position sensor is removed, now time to install the new one.

  • Install New Sensor

    Install the new crankshaft sensor where the old one was removed.

  • Align New Sensor

    Align the new sensor so the retention bolt hole lines up with the threads on the engine side.

  • Hand-thread Retention Bolt

    Handthread the sensor retention bolt into place to fully align the sensor to the engine.

  • Torque Retention Bolt

    Hand-torque the sensor retention bolt so the sensor is snugly installed.

  • Re-plug Electrical Connector

    Re-plug the crankshaft sensor electrical connector until it clips into place.

  • Clean Engine Codes

    Use a scan tool to clear all engine codes, to ensure the P0335 crankshaft position sensor code is gone.

  • Test Start Vehicle

    To ensure there are no issues with the new sensor and the issue is fixed, test start the vehicle.

  • DIY Complete!

    Congrats on replacing your crankshaft position sensor! Keep an eye on your check engine codes in the future to ensure the P0335 code doesn't come back, indicating a long-term issue.
