P0020

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

DTC P0010 - Camshaft Position "A" Actuator Circuit (Bank 1)

DTC 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: 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 (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
NG -- REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2)
OK -- REPLACE CAMSHAFT TIMING CONTROL MOTOR (BANK 1 OR BANK 2)
