DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0848 | Transmission Fluid Pressure Sensor/Switch B Circuit Low | The secondary pressure sensor voltage is 4.7
V or more continuously for 5 seconds or more
under the following diagnosis conditions: - Diagnosis conditions - CVT fluid temperature: −20C (−4F) or more - Secondary pressure target value: 5.7 MPa or less - TCM power supply voltage: More than 11 V |
- Harness or connector
(Secondary pressure sensor circuit is
shorted to power supply) - Secondary pressure sensor - Control valve assembly |
DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, the 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 : −19C (−2.2F) or more
With GST
CAUTION: When the ambient temperature is −20C (−4F) or less and the engine is cold, warm up the engine for approximately 5 minutes.
Is "P0848"detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK SECONDARY PRESSURE SENSOR POWER SUPPLY CIRCUIT
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK SECONDARY PRESSURE SENSOR SIGNAL CIRCUIT
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.CHECK TCM INPUT SIGNALS
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> There is a malfunction of secondary pressure sensor. Replace transaxle assembly. Refer to TM "Removal and Installation".
