Performing a SYSTEM CHECK enables the system,
which consists of the multiple actuators, to be operated
without removing any parts. In addition, it can show
whether or not any DTCs are set, a ...
Camshaft Position "A" Actuator Circuit
DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve
(OCV) and VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control sig ...

Precaution
NOTICE:
Because the compressor operates at high voltages, wear
electric insulated gloves and pull out the service plug to
cut the high-voltage circuit before inspection.
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT T ...
Air Mix Damper Position Sensor Circuit (Passenger Side)
DESCRIPTION
This sensor detects the position of the air mix control servo motor (air mix
damper) and sends the
appropriate signals to the A/C amplifier. The position sensor is built in the
air mix control servo motor. The
position sensor's resistance changes as the air mix control servo m ...
Key Lock-in Prevention Function does not Work Properly (Manual
Operation and Operation Interlocked with Key are Active)
DESCRIPTION
The un-lock warning switch turns ON when the key is inserted in the ignition
key cylinder. The courtesy
light switch turns ON when the driver side door is opened. These 2 switches are
monitored by the body
ECU.
In order to prevent the key from being locked in, the body ECU cont ...
