The crankshaft position sensor reads the rotation of the crankshaft, which the computer translates to determine engine-timing sequences. The computer uses this reading, in conjunction with the camshaft position sensor, to determine proper fuel injection and ignition timing.
Removal & Installation
- Disconnect the negative battery cable.
- Remove the necessary accessory drive belts to access the sensor.
- If necessary, remove the engine oil dipstick tube.
- Remove the sensor-attaching bolt, and then withdraw the sensor from the engine.
- Installation is the reverse of the removal procedure.
- Remove the right side driveshaft.
- Remove the cylinder block lower blind plug and install the special service tool or equivalent.
- Turn the crankshaft pulley to the clockwise until it stops.
Using a straight edge, draw a straight line directly in the center of the ninth tooth of the crankshaft pulley pulse wheel (counting counterclockwise from the empty space).
NOTEIf the line is not accurately drawn, ignition timing, fuel injection and other engine control systems will be adversely affected. Drawn the straight line carefully using a straight edge.
- Align the centerline of the crankshaft position sensor and the line drawn, then install the sensor.
- Install the CKP sensor fitting bolts. Tightening torque 4.1-5.5 ft lbs
- Remove the special service tool or equivalent then install the cylinder block lower blind plug. Tightening torque 15 ft lbs
- Install the right side driveshaft.
- Install the splash shield.
- Install the right front wheel
- Remove the right front wheel.
- Remove the splash shield.
- Disconnect the CKP sensor connector.
- Remove the installation bolts to remove the CKP sensor.
