DTC P0345 CAMSHAFT POSITION SENSOR "A" CIRCUIT (BANK 2)

1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of camshaft position sensor. Judge NG when the number of camshaft signal remains to be abnormal.







2. COMPONENT DESCRIPTION




3. ENABLE CONDITION

4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.

5. DIAGNOSTIC METHOD




- Abnormality Judgment
Judge NG when condition continues 3 seconds or more: the amount of camshaft sensor signal during engine 2 revs. are not 3 times.
Judge OK and clear NG when the malfunction criteria is not completed.




- Normality Judgment
Judge OK and clear the NG when the malfunction criteria are completed.

6. DTC CLEAR CONDITION
- When the OK idling cycle was completed 40 times in a row
- When "Clear Memory" was performed

7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITION
- When the OK driving cycle was completed 3 times in a row
- When "Clear Memory" was performed

8. FAIL SAFE
- Ignition timing whole learning compensation:
- Enter the initial value (whole learning compensation factor = 0.5, Variable amount of whole learning compensation factor = 0.25) to the whole learning compensation factor and variable amount of whole learning compensation factor when IG OFF, and then make the whole learning incomplete.
- Enter the initial value (whole learning compensation factor = 0.5, Variable amount of whole learning compensation factor = 0.25) to the whole learning compensation factor and variable amount of whole learning compensation factor when making a normality judgment from abnormality judgment, and then make the whole learning incomplete.
- Ignition timing partial learning compensation:
- Enter the initial value (0 degree CA) to the compensation value of partial learning zone when IG OFF.
- Enter the initial value (0 degree CA) to the compensation value of partial learning zone when making a normality judgment from abnormality judgment.
- AVCS control: Most timing retard learning is not complete or most timing retard learning completion is not experienced.
- ISC feedback compensation:
- Do not perform the AVCS actual timing advance compensation.
- Make the OCV driving Duty to be the given value (9.36%).

9. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
