DTC P0011 INTAKE CAMSHAFT POSITION TIMING - OVER-ADVANCED (BANK 1)

1. OUTLINE OF DIAGNOSIS
Detect the malfunction of AVCS system.




2. COMPONENT DESCRIPTION




3. ENABLE CONDITION (FOR ABNORMALITY JUDGMENT ONLY)

4. GENERAL DRIVING CYCLE
1. Always perform the diagnosis after warming up when the engine speed increases and AVCS operates.
2. Always perform the diagnosis after warming up the engine.

5. DIAGNOSTIC METHOD
1. Judge NG when the difference of the amount of AVCS target timing advance and the amount of AVCS actual timing advance becomes large.
2. Judge NG when the most retarded learning value is outside of the normal range.




- Abnormality Judgment
Judge NG when the continuous time of completing the malfunction criteria becomes more than 20 seconds.




- Normality Judgment
Judge OK and clear the NG when the continuous time of completing the malfunction criteria becomes more than 1 second.

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)
