POSSIBLE CAUSE
FAIL-SAFE
Not changed from normal driving
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.CHECK DTC DETECTION
With CONSULT
FLUID TEMP : More than −20°C (−4°F)
With GST
CAUTION: When the ambient temperature is less than −20°C (−4°F) and the engine is cold, warm up the engine for approximately 5 minutes.
Is “P084D”detected? YES >> Go to TM-152, "Diagnosis Procedure".
NO-1 >> To check malfunction symptom before repair: Refer to GI-41, "Intermittent Incident".
NO-2 >> Confirmation after repair: INSPECTION END
Diagnosis Procedure
1.CHECK TCM INPUT SIGNALS

Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK PRIMARY PRESSURE SENSOR POWER CIRCUIT

Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.CHECK PRIMARY PRESSURE SENSOR SIGNAL CIRCUIT
Check voltage between CVT unit harness connector terminal and ground.

Is the inspection result normal? YES >> There is malfunction of primary pressure sensor. Replace transaxle assembly. Refer to TM-220, "Removal and Installation".
NO >> Repair or replace malfunctioning parts.

DESCRIPTION
In general, testing electrical circuits is an easy task if it is
approached in a logical and organized method.
Before beginning it is important to have all available information on the
system to be tested. Also, get a thorough
understanding of system operation. Then y ...
