P0010

2UR-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 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 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.

INSPECTION PROCEDURE

HINT
- When viewed from the rear of the engine assembly, Bank 1 is on the left side and Bank 2 is on the right side.
- 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. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY (for Bank 1 or Bank 2)

(a) Turn the power 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

NG -- REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (for Bank 1 or Bank 2) Engine

OK -- REPLACE CAMSHAFT TIMING CONTROL MOTOR (for Bank 1 or Bank 2) Removal
