DTC 07, 11, 13, 19, 22

A/C amplifier (sensor ground) system inspection

POSSIBLE CAUSE
•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and evaporator temperature sensor connector terminal A
•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and ambient temperature sensor connector terminal A
•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and cabin temperature sensor connector terminal A
•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and air mix actuator connector terminal A (L.H.D.), C (R.H.D.)
•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and airflow mode actuator connector terminal C

Diagnostic Procedure

STEP

INSPECTION

ACTION

1
INSPECT SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT
•  Disconnect the A/C amplifier connector (16-pin) and the evaporator temperature sensor connector.
•  Is there an open circuit in the wiring harness between A/C amplifier connector (16-pin) terminal 2N and evaporator temperature sensor connector terminal A?
Yes
Repair the wiring harness.
No
The system is normal at present. (Clear the past malfunction from memory.)
