DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
- Start the engine and wait for 10 seconds or more.
- Check the first trip DTC.
Is “P0712” detected? YES >> Go to TM-174, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
- Turn ignition switch OFF.
- Disconnect TCM connector and CVT unit connector.
- Check continuity between TCM harness connector terminal and ground.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace malfunctioning part.
2.CHECK CVT FLUID TEMPERATURE SENSOR
Check CVT fluid temperature sensor. Refer to TM-174, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
Component Inspection
1.CHECK CVT FLUID TEMPERATURE SENSOR
Check resistance between CVT unit connector terminals.
Is the inspection result normal? YES >> INSPECTION END
NO >> There is a malfunction of CVT fluid temperature sensor. Replace transaxle assembly. Refer to TM-283, "Removal and Installation".

DTC DETECTION LOGIC
To judge the malfunction of A/F sensor 1, this diagnosis measures response
time of the A/F signal computed
by ECM from the A/F sensor 1 signal. The time is compensated by engine operating
(speed and load), fuel
feedback control constant, and the A/F sensor 1 tem ...
