Subaru Outback: Crankshaft Position Sensor

A: REMOVAL

1) Disconnect the ground cable from battery.

2) Remove the bolt which secures crankshaft position sensor to oil pump.

3) Remove the crankshaft position sensor, and disconnect the connector from the crankshaft position sensor.

B: INSTALLATION

Install in the reverse order of removal.

Tightening torque: 6.4 N*m (0.7 kgf-m, 4.7 ft-lb)

C: INSPECTION

1. CRANKSHAFT POSITION SENSOR (METHOD WITH CIRCUIT TESTER)

Measure the resistance between crankshaft position sensor terminals.

2. CRANKSHAFT POSITION SENSOR (METHOD WITH OSCILLOSCOPE)

1) Prepare an oscilloscope.

2) Remove the glove box lid assembly.

3) Connect the probe to ECM connector.

1. To ECM connector

4) Start the engine and let it idle.

5) Check the pattern is the same as the waveform and voltage shown below.

1. One crankshaft rotation

6) After inspection, install the related parts in the reverse order of removal.

3. OTHER INSPECTIONS

Check that the crankshaft position sensor has no deformation, cracks or other damages.

Camshaft Position Sensor

A: REMOVAL

1) Disconnect the ground cable from battery.

2) Disconnect the connector from camshaft position sensor.

3) Remove the ignition coil. (LH side only)

4) Remove the bolt which secures camshaft position sensor to camshaft position sensor support.

5) Remove the bolt which secures camshaft position sensor support to camshaft cap LH.

6) Remove the camshaft position sensor and the camshaft position sensor support as a unit.

NOTE: Slide in the arrowed direction until the camshaft position sensor contacts the rocker cover LH.

7) Remove the camshaft position sensor from the camshaft position sensor support.
