WARNING: This page is about a different variant/trim than selected.
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK POWER SUPPLY OF CAMSHAFT POSITION SENSOR.
|
Is the voltage 10 V or more? | Go to step 2. | Repair the harness and connector.
NOTE:
In this case, repair the following item:
|
2 CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR CONNECTOR.
|
Is the resistance less than 1 Ω? | Go to step 3. | Repair the harness and connector.
NOTE:
In this case, repair the following item:
|
| 3 CHECK HARNESS BETWEEN ECM AND CAMSHAFT POSITION SENSOR CONNECTOR. Measure the resistance between camshaft position sensor connector and engine ground. Connector & terminal (E36) No. 2 - Engine ground: |
Is the resistance 1 MΩ or more? | Go to step 4. | 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 (E36) 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 . |
| 5 CHECK CONDITION OF CAMSHAFT POSITION SENSOR. | Is the camshaft position sensor installation bolt tightened securely? | Go to step 6. | Tighten the camshaft position sensor installation bolt securely. |
| 6 CHECK CAMSHAFT POSITION SENSOR. Check the waveform of the camshaft position sensor. Refer to , ENGINE CONTROL MODULE (ECM) I/O SIGNAL . |
Is there any abnormality in waveform? | Replace the camshaft position sensor. Refer to CAMSHAFT POSITION SENSOR Camshaft Position Sensor. | Repair the following item.
