ENGINE (DIAGNOSTICS)(H4DO) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)
DTC P0011 "A" CAMSHAFT POSITION - TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 1
DTC detecting condition:
Detected when two consecutive driving cycles with fault occur.
Trouble symptom:
• Engine stall
• Improper idling
CAUTION:
After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION">, and Inspection Mode Inspection Mode > PROCEDURE">.
STEP | CHECK | YES | NO |
1.IDENTIFYING FAULTY PART.
1) Perform the Clear Memory Mode. Clear Memory Mode">
2) Replace the defective oil control solenoid by the other (RH or LH, intake side or exhaust side) oil control solenoid.
3) Perform appropriate drive cycle test. Drive Cycle">
4) Make sure that the fault occurrence (DTC and incorrect advancing) has shifted to the other location.
Did the detected DTC shift to the location where the oil control solenoid was replaced?
Replace the faulty oil control solenoid.

2.CHECK CURRENT DATA.
1) Start the engine and let it idle.
2) Read the value of «VVT Adv. Ang. Amount R» using the Subaru Select Monitor.
NOTE:
For detailed operation procedures, refer to “Current Data Display For Engine”. Subaru Select Monitor">
Is the value of «VVT Adv. Ang. Amount R» approx. 0 deg?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0011 "A" CAMSHAFT POSITION - TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 1">Go to Step 3.
Check the following item and repair or replace if necessary.
• Intake cam sprocket (clog or dirt of oil routing, setting of spring)
• Intake camshaft (dirt, damage of camshaft)
3.CHECK CURRENT DATA.
1) Drive with acceleration and deceleration at 80 km/h (50 MPH) or less.
NOTE:
Drive to an extent that the duty output of oil flow control solenoid valve increases.
2) Read the values of «OCV Duty R» and «VVT Adv. Ang. Amount R» using the Subaru Select Monitor.
NOTE:
For detailed operation procedures, refer to “Current Data Display For Engine”. Subaru Select Monitor">
When the value of «OCV Duty R» increases more than 10%, is the value of «VVT Adv. Ang. Amount R» approx. 0 deg?
Check the following item and repair or replace if necessary.
• Intake cam sprocket (clog or dirt of oil routing, setting of spring)
• Intake camshaft (dirt, damage of camshaft)
Perform the following procedures, and clean the oil routing.
Replace the engine oil and idle the engine for 5 minutes, and then replace the oil filter and engine oil. Engine Oil > REPLACEMENT"> Engine Oil Filter">
1. OUTLINE OF DIAGNOSIS
Detect the AVCS system malfunction.
Judge as NG when the conditions during which the differences of AVCS target timing advance amount and AVCS actual timing advance amount is large continues.
2. EXECUTION CONDITION
• Target error
Secondary parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
AVCS control | In operation |
• Intermediate lock position
Secondary parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
Engine speed | ≥ 500 rpm |
Elapsed time after starting the engine | > 500 ms and ≤ Value from Map |
Engine coolant temperature at engine starting °C (°F) | −40 (−40) | −30 (−22) | −20 (−4) | −10 (14) | 0 (32) | 10 (50) | 20 (68) | 30 (86) |
Elapsed time after starting the engine ms | 10000 | 10000 | 10000 | 8000 | 5000 | 3500 | 2800 | 2800 |
Engine coolant temperature at engine starting °C (°F) | 40 (104) | 50 (122) | 60 (140) | 70 (158) | 80 (176) | 90 (194) | 100 (212) | 110 (230) |

3. GENERAL DRIVING CYCLE
• Normal
Perform the diagnosis continuously when the engine speed increases and AVCS operates.
• Intermediate lock
Perform the diagnosis when the AVCS is carrying out the intermediate lock control at the engine start.
4. DIAGNOSTIC METHOD
When the conditions during which the differences of AVCS target timing advance amount and AVCS actual timing advance amount is large continues for certain amount of time.
Judge as NG when the following conditions are established within the predetermined time.
Malfunction Criteria | Threshold Value |
•Target error | |
|(Target position − Actual position)| | > 10 °CA |
•Intermediate lock position | |
|(Target position − Actual position)| | > 10 °CA |
Time needed for diagnosis:
• Target error: 10000 ms
• Intermediate lock position: 2000 ms
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
