DTC PROCEDURE

Step Check Yes No
1 CHECK POWER SUPPLY OF CAMSHAFT POSITION SENSOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from camshaft position sensor.
  3. Turn the ignition switch to ON.
  4. Measure the voltage between camshaft position sensor connector and engine ground.

    Connector & terminal 

    (E62) No. 1 (+) - Engine ground (-): 

Is the voltage 10 V or more? Go to step . Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in harness between main relay and camshaft position sensor connector
  • Poor contact of coupling connector
2 CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from ECM.
  3. Measure the resistance between ECM and camshaft position sensor connector.

    Connector & terminal 

    (E158) No. 32 - (E62) No. 2: 

    (E158) No. 34 - (E62) No. 3: 

Is the resistance less than 1 Ω? Go to step . Repair the open circuit in harness between ECM and camshaft position sensor connector.
3 CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR CONNECTOR. 
Measure the resistance between camshaft position sensor connector and engine ground.
Connector & terminal 
(E62) No. 2 - Engine ground: 
Is the resistance 1 MΩ or more? Go to step . Repair short circuit to ground in harness between ECM and camshaft position sensor connector.
4 CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR CONNECTOR. 
Measure the voltage between camshaft position sensor connector and engine ground.
Connector & terminal 
(E62) No. 2 (+) - Engine ground (-): 
Is the voltage 5 V or more? Repair the short circuit to power in the harness between ECM and camshaft position sensor connector. Go to step .
5 CHECK CONDITION OF CAMSHAFT POSITION SENSOR.  Is the camshaft position sensor installation bolt tightened securely? Go to step . Tighten the camshaft position sensor installation bolt securely. < Ref. to INSTALLATION , Camshaft Position Sensor. >
6 CHECK CAMSHAFT POSITION SENSOR. 
Check the waveform of the camshaft position sensor. < Ref. to ENGINE CONTROL MODULE (ECM) I/O SIGNAL . >
Is there any abnormality in waveform? Replace the camshaft position sensor. < Ref. to CAMSHAFT POSITION SENSOR . > Repair the following item.
  • Poor contact of ECM connector
  • Poor contact of camshaft position sensor connector
  • Poor contact of coupling connector

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
