WIRING DIAGRAM

10AG1: CHECK ANY OTHER DTC ON DISPLAY

CHECK: Does the Subaru Select Monitor or OBD-II general scan tool indicate DTC P0340?

YES: Inspect DTC P0340 using 10. Diagnostics Chart with Trouble Code for 2200 cc Models".

NO: Go to step 1OAG2.

10AG2: CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.
1. Turn ignition switch to OFF.
2. Disconnect connector from camshaft position sensor.

Connector & terminal (E15) No.1 - Engine ground:

3. Measure resistance of harness between camshaft position sensor connector and engine ground.

CHECK: Is the resistance more than 100 K.Ohm?

YES: Repair harness and connector.

NOTE: In this case, repair the following:
- Open circuit in harness between camshaft position sensor and ECM connector
- Poor contact in ECM connector
- Poor contact in coupling connector (B21)

NO: Go to step 10AG3.

10AG3: CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.

Connector & terminal (E15) No.1 - Engine ground:

Measure resistance of harness between camshaft position sensor connector and engine ground.

CHECK: Is the resistance less than 10 ohm?

YES: Repair ground short circuit in harness between camshaft position sensor and ECM connector.

NOTE: The harness between both connectors are shielded. Repair ground short circuit in harness together with shield.

NO: Go to step 10AG4.

10AG4: CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.

Connector & terminal (E15) No.2 - Engine ground:

Measure resistance of harness between camshaft position sensor connector and engine ground.

CHECK: Is the resistance less than 5 ohm?

YES: Go to step 10AG5.

NO: Repair harness and connector.

NOTE: In this case, repair the following:
- Open circuit in harness between camshaft position sensor and ECM connector
- Poor contact in ECM connector
- Poor contact in coupling connector (B21)

10AG5: CHECK CONDITION OF CAMSHAFT POSITION SENSOR.

CHECK: Is the camshaft position sensor installation bolt tightened securely?

YES: Go to step 10AG6.

NO: Tighten camshaft position sensor installation bolt securely.

10AG6: CHECK CAMSHAFT POSITION SENSOR.
1. Remove camshaft position sensor.

Terminals No.1 - No.2:

2. Measure resistance between connector terminals of camshaft position sensor.

CHECK: Is the resistance between 1 and 4 K.Ohm?

YES: Go to step 10AG7.

NO: Replace camshaft position sensor.

10AG7: CHECK CONDITION OF CAMSHAFT POSITION SENSOR.
Turn ignition switch to OFF.

CHECK: Is the camshaft position sensor installation bolt tightened securely?

YES: Go to step 10AG8.

NO: Tighten camshaft position sensor installation bolt securely.

10AG8: CHECK CAMSHAFT SPROCKET.
Remove front belt cover.

CHECK: Are camshaft sprocket teeth cracked or damaged?

YES: Replace camshaft sprocket.

NO: Go to step 10AG9.

10AG9: CHECK INSTALLATION CONDITION OF TIMING BELT.




Turn camshaft using ST, and align alignment mark on camshaft sprocket with alignment mark on timing belt cover LH.

ST 499207100 CAMSHAFT SPROCKET WRENCH

CHECK: Is timing belt dislocated from its proper position?

YES: Repair installation condition of timing belt.

NO: Replace camshaft position sensor.
