(a) Replace the A/C pressure sensor See: Heating and Air Conditioning/Refrigerant Pressure Sensor / Switch/Service and
Repair/Removal.
HINT
Since the A/C pressure sensor cannot be inspected while it is removed from the vehicle, replace the A/C pressure sensor with a
new or a known good one and check that the condition returns to normal.
NEXT -- Continue to next step.
2. RECHECK FOR DTC
(a) Recheck for the DTC when the following conditions are satisfied.
NOTICE:
If refrigerant pressure on the high pressure line is excessive, this DTC will be set. Therefore, it is necessary to measure the voltage
over a period of time (approximately 10 minutes) because this DTC may be set after the A/C has been operating for a while.
HINT
When the outside air temperature is low (below -1.5锟斤拷C (29.3锟斤拷F)), the compressor stops due to signals from the ambient
temperature sensor and the evaporator temperature sensor to prevent the evaporator from freezing. In this case, perform the
inspection in a warm indoor environment.
Result:
B -- REPLACE A/C AMPLIFIER

HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM: B1441/41: Air Mix Damper Control Servo Motor Circuit
(Passenger Side)
B1441/41 - Air Mix Damper Control Servo Motor Circuit (Passenger Side)
DESCRIPTION
The air mix control servo motor sends pulse signals to indicate the damper position to the A/C amplifier. The A/C amplifier activates the motor
(normal or reverse) based on these signals to move the air mix damper (front passenger side) to any position. As a result, the amount of air passing
through the heater core after passing through the evaporator is adjusted, and the temperature of the air blowing toward the passenger side is
controlled.
The A/C amplifier communicates with the servo through a communication/driver IC and wiring assembly called the air conditioning harness.
HINT
Confirm that no mechanical problem is present because this DTC can be output when either a damper link or the damper is
