MWI AMBIENT SENSOR SIGNAL CIRCUIT MWI-67 < DTC/CIRCUIT DIAGNOSIS > C D E F G H I J K L M B A O P AMBIENT SENSOR SIGNAL CIRCUIT Description INFOID:0000000011279820 It detects outside air temperature and converts it into a resistance value which is then input into the combina- tion meter. Diagnosis Procedure INFOID:0000000011279821 Regarding Wiring Diagram information, refer to . 1. CHECK AMBIENT SENSOR SIGNAL CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect combination meter connector and ambient sensor connector. 3. Check continuity between combination meter harness connector and ambient sensor harness connector. 4. Check continuity between combination meter harness connector and ground. Is the inspection result normal? YES >> GO TO 2. NO >> Repair or replace harness or connector. 2. CHECK AMBIENT SENSOR SIGNAL GROUND CIRCUIT Check continuity between combination meter harness connector and ambient sensor harness connector. Is the inspection result normal? YES >> Inspection End. NO >> Repair or replace harness or connector. Component Inspection INFOID:0000000011279822 1. CHECK AMBIENT SENSOR 1. Turn ignition switch OFF. 2. Disconnect ambient sensor connector. 3. Check resistance between ambient sensor terminals.
