P0011

1UR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0011: Camshaft Position "A" - Timing Over-Advanced or System Performance (Bank 1)

DTC P0011 - Camshaft Position "A" - Timing Over-Advanced or System Performance (Bank 1)

DTC P0021 - Camshaft Position "A" - Timing Over-Advanced or System Performance (Bank 2)

DESCRIPTION

The VVT-iE system changes the valve timing with the motor.
The camshaft control timing motor is equipped with a self diagnostic function, which is used to output diagnosis signals (VTM) to the ECM.













CAMSHAFT CONTROL MOTOR SYMPTOMS AND FAIL-SAFE DURING MALFUNCTION





MONITOR DESCRIPTION

This DTC is output when a valve timing stuck condition is detected. When the valve timing is in the advance angle position, if the valve timing does not vary, and there is a large difference in the target and actual valve timing, it is determined that a malfunction has occurred. When this malfunction is detected, a DTC is output immediately (1 trip detection logic). After the engine is warmed up, if the vehicle is idled for 5 minutes, a DTC is output.

INSPECTION PROCEDURE
HINT:
- Techstream only:
By using the Active Test's Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) function, it can be determined if the VVT-iE system is malfunctioning.
1 Connect the Techstream to the DLC3.
2 Turn the engine switch on (IG) and turn the Techstream ON.
3 Start the engine and warm it up.
4 Enter the following menus: Powertrain / Engine / Active Test / Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) / All Data / VVT-iE Aim Angle #1 and VVT Change Angle #1 or VVT-iE Aim Angle #2 and VVT Change Angle #2.
5 Perform the Active Test operation with the engine speed at 1500 rpm.
OK:





- Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011 OR P0021)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream ON.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read DTCs.
Result:






B -- GO TO DTC CHART SFI System
A -- Continue to next step.

2. REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2)
(a) Replace the camshaft timing gear assembly Disassembly.
NEXT -- Continue to next step.

3. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream ON.
(d) Clear DTCs DTC Check / Clear.
(e) Start the engine and idling for 5 minutes.
(f) Enter the following menus: Powertrain / Engine / Trouble Codes.
(g) Read the DTCs.
Result:






B -- GO TO DTC CHART SFI System
A -- END
