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.
