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".

Additional service when replacing
TCM
Description
Always perform the following items when the TCM is replaced.
LOADING OF THE CALIBRATION DATA
The TCM acquires calibration data (individual characteristic value) of
each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform
accur ...
Pedal vibration or ABS operation
sound occurs
Diagnosis Procedure
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when
brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
When shifting gears
When driving on slippery road
During cornering at high speed
When passing o ...
