1UR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0010,P0020: Camshaft Position "A" Actuator Circuit (Bank 1)
P0020 - Camshaft Position "A" Actuator Circuit (Bank 2)

DESCRIPTION

The electric VVT changes the valve timing according to the motor. In comparison to a conventional hydraulic VVT, the valve timing range is greater and the VVT operates even when the engine speed is low or the engine is cold. As a result, it is possible to increase engine output and mileage.

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 an IC overheat malfunction or an overcurrent malfunction is detected in the intake side camshaft timing control motor. The camshaft timing control motor is equipped with a self diagnostic function, which is used to output diagnosis signals (VTM) to the ECM. If the ECM receives a motor driver interior malfunction signal, a DTC is output immediately (1 trip detection logic). If the engine is idled for 10 seconds, a DTC is detected.

TYPICAL MALFUNCTION THRESHOLDS





CONFIRMATION DRIVING PATTERN





- Connect the Techstream to the DLC3.

- Turn the engine switch on (IG) and turn the Techstream on.

- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) DTC Check / Clear.

- Turn the engine switch off and wait for 30 seconds.

- Turn the engine switch on (IG) and turn the Techstream on [A].

- Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or more [B].

- Idle the engine for 10 seconds [C].

- Enter the following menus: Powertrain / Engine / Trouble Codes.

- Read the DTC [D].

HINT
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.

- Input the DTC: P0010 or P0020.

- Check the DTC judgment result.





HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform step [C] again.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.

- Check the DTC judgment result.

HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
- If the test result is INCOMPLETE or UNKNOWN and no DTC is output, perform a universal trip and check for permanent DTCs DTC Check / Clear.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
INSPECTION PROCEDURE

HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE

1. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2)

(a) Turn the engine switch off.

(b) Remove the camshaft timing control motor Removal.

(c) Check if the camshaft timing gear assembly's eccentric shaft rotates smoothly.





OK:

Rotates smoothly

(d) Reinstall the camshaft timing control motor.

NG -- REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2) Components

OK -- REPLACE CAMSHAFT TIMING CONTROL MOTOR (BANK 1 OR BANK 2) Components
