Rear Air Mix Damper Position Sensor Circuit
DESCRIPTION
This sensor detects the position of the rear air mix control servo motor
(water valve servo motor) and
sends the appropriate signals to the A/C amplifier. The position sensor is built
in the rear air mix control
servo motor (water valve servo motor).
The position sensor's r ...
Shifting the shift lever
While the engine switch is in the
“ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system), move the shift lever with the brake pedal
depressed.
When shifting the shift lever between P and D, make sure that the vehicle
is completely ...
Cold Start Ignition Timing Performance
DESCRIPTION
This monitor will run when the engine is started at -10 to 50°C (14 to 122°F)
of the engine coolant
temperature. The DTC will set after the engine idling for 13 seconds (2 trip
detection logic).
The DTC is designed to monitor the idle air control at cold start. When the
