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 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 rpm 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.

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