Nissan Sentra Service Manual: Ambient sensor signal circuit
Description
It detects outside air temperature and converts it into a resistance value which is then input into the combination meter.
Diagnosis Procedure
Regarding wiring diagram information, refer to mwi-28, "wiring diagram".
1.Check ambient sensor signal circuit
- Turn ignition switch off.
- Disconnect combination meter connector and ambient sensor connector.
- Check continuity between combination meter harness connector and ambient sensor harness connector.
- 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
1.Check ambient sensor
- Turn ignition switch OFF.
- Disconnect ambient sensor connector.
- Check resistance between ambient sensor terminals.
Is the inspection result normal? Yes >> inspection end.
No >> replace ambient sensor. Refer to hac-106, "removal and installation".
