CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>GENERAL DESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD .

NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

CHECK EXHAUST CAMSHAFT POSITION SENSOR RH POWER SUPPLY .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from the exhaust camshaft position sensor RH.
3. Turn the ignition switch to ON.
4. Measure the voltage between exhaust camshaft position sensor RH connector and engine ground.
  Connector & terminal
  
  (E62) No. 1 (+) - Engine ground (-):
Is the voltage 10 V or more?

Yes: Go to 2 .

No: Repair the following item.
- Open circuit in harness between M/B and camshaft position sensor RH connector
- Poor contact of coupling connector
- Blown out of fuse
CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR RH CONNECTOR (OPEN) .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from ECM.
3. Measure the resistance between ECM connector and camshaft position sensor RH connector.
  Connector & terminal
  
  (E158) No. 51 - (E62) No. 3:
  
  (E158) No. 65 - (E62) No. 2:
Is the resistance less than 1 Ω?

Yes: Go to 3 .

No: Repair the open circuit in the harness between the ECM connector and camshaft position sensor RH connector.
CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR RH CONNECTOR (SHORT TO GROUND) .
Measure the resistance between camshaft position sensor RH connector and engine ground.

Connector & terminal

(E62) No. 2 - Engine ground:

Is the resistance 1 MΩ or more?

Yes: Go to 4 .

No: Repair short circuit to ground in harness between ECM connector and camshaft position sensor RH connector.
CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR RH CONNECTOR (SHORT TO POWER SUPPLY) .
Measure the voltage between camshaft position sensor RH connector and engine ground.

Connector & terminal

(E62) No. 2 (+) - Engine ground (-):

Is the voltage 5 V or more?

Yes: Repair the short circuit to power in the harness between ECM connector and camshaft position sensor RH connector.

No: Go to 5 .
CHECK CONDITION OF CAMSHAFT POSITION SENSOR RH .
Check the installation condition of camshaft position sensor RH.

Is the camshaft position sensor RH installation bolt tightened securely?

Yes: Go to 6 .

No: Tighten the camshaft position sensor RH installation bolt securely. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>CAMSHAFT POSITION SENSOR>INSTALLATION .
CHECK CAMSHAFT POSITION SENSOR RH .
Check the waveform of the camshaft position sensor RH. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>CONTROL MODULE I/O SIGNAL .

Is there any abnormality in waveform?

Yes: Replace the camshaft position sensor RH. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>CAMSHAFT POSITION SENSOR .

No: Repair the following item.
- Poor contact of ECM connector
- Poor contact of camshaft position sensor RH connector
- Poor contact of coupling connector
