OAT SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000001078082

The OAT sensor is attached on the radiator core support (left side). It detects ambient temperature and con-
verts it into a resistance value which is then input into the combination meter.

Diagnosis Procedure

INFOID:0000000001078083

1.

CHECK OAT SENSOR CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect combination meter connector and OAT sensor connector.

3.

Check continuity between combination meter harness connector terminal 20 and oil level sensor harness
connector terminal 1.

4.

Check continuity between combination meter harness connector terminal 20 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK OAT SENSOR GROUND CIRCUIT

1.

Check continuity between combination meter harness connector terminal 19 and OAT sensor harness
connector terminal 2.

2.

Check continuity between combination meter harness connector terminal 19 and ground.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Repair harness or connector.
