AMBIENT SENSOR SIGNAL CIRCUIT
AMBIENT SENSOR SIGNAL CIRCUIT
DescriptionINFOID:0000000001537467
The ambient sensor detects ambient temperature and converts it into a resistance value which is then input
into the combination meter.
NOTE:
On vehicles equipped with auto A/C, the ambient sensor signal is shared with the front air control. The combi-
nation meter is notified of the signal sharing via the auto A/C sense circuit.
Diagnosis ProcedureINFOID:0000000001537468
1.CHECK AMBIENT SENSOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect combination meter connector and ambient sensor
connector.
3. Check continuity between combination meter harness connector
M24 (A) terminal 19 and ambient sensor harness connector E60
(B) terminal 2.
4. Check continuity between combination meter harness connector
M24 (A) terminal 19 and ground.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair harness or connector.
2.CHECK AMBIENT SENSOR GROUND CIRCUIT
1. Check continuity between combination meter harness connector
M24 (A) terminal 20 and ambient sensor harness connector E60
(B) terminal 1.
2. Check continuity between combination meter harness connector
M24 (A) terminal 20 and ground.
Is the inspection result normal?
YES >>  With auto A/C: GO TO 3
 Without auto A/C: INSPECTION END
NO >> Repair harness or connector.
3.CHECK AUTO A/C SENSE SIGNAL
1. Connect combination meter and ambient sensor connectors.
2. Turn ignition switch ON.
3. Check voltage between combination meter harness connector
M24 terminal 25 and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 419 – 2 : Continuity should exist.
19 – Ground : Continuity should not exist.

SYMPTOM DIAGNOSIS
THE FUEL GAUGE POINTER DOES NOT MOVE
DescriptionINFOID:0000000001374712
Fuel gauge needle will not move from a certain position.
Diagnosis ProcedureINFOID:0000000001374713
1.CHECK COMBINATION METER INPUT SIGNAL
1. Select “METER/M&A” on CONSULT-III.
2. Using “FUEL METER” of “DATA MONITOR”, compare the monitor value with the fuel gauge reading on
the combination meter. Refer to MWI-29, "
Component Function Check".
Does monitor value match fuel gauge reading?
YES >> GO TO 2
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
2.CHECK FUEL LEVEL SENSOR SIGNAL CIRCUIT
Check the fuel level sensor signal circuit. Refer to MWI-29, "
DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
3.CHECK FUEL LEVEL SENSOR UNIT
Perform a unit check for the fuel level sensor unit. Refer to MWI-30, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4
NO >> Replace fuel level sensor unit and fuel pump. Refer to FL-8, "
Removal and Installation".
4.CHECK FLOAT INTERFERENCE
Check that the float arm does not interfere or bind with any of the components in the fuel tank.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-94, "Removal and Installation".
NO >> Repair or replace malfunctioning parts.
