DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0846 | Transmission Fluid Pressure Sensor/Switch B Circuit Range/Performance | The detection conditions continuously for 5
seconds or more under the following diagnosis
conditions: - Diagnosis conditions - Selector lever: "D" position - The primary pulley speed experienced 306 rpm or more and the secondary pulley speed experienced 230 rpm or more at least once. - Wheel spin is not being detected. - The rate of change in pulley ratio: Between −0.09 and +0.09 inclusive - Solenoid valve output current: 750 mA or more - GND short diagnosis of the solenoid valve circuit is not satisfied. - TCM power supply voltage: More than 11 V - Detection conditions - After the value of "Actual secondary pressure − Target secondary pressure" exceeds 0.675 MPa: - The rate of change in vehicle speed [km/h (MPH)]: Between −49 (−30) and +49 (+30) inclusive - The rate of change in accelerator pedal angle: Between −1.3/8 and +1.3/8 inclusive |
- Secondary pressure sensor - Control valve assembly |
CAUTION: Be careful of the driving speed.
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
CAUTION: At the same time, the accelerator pedal angle must be maintained constant.
Is "P0846"detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK TCM INPUT SIGNAL
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> There is a malfunction of secondary pressure sensor value. Replace transaxle assembly. Refer to TM "Removal and Installation".

The following tables show the standard maintenance
schedule. Depending upon weather and
atmospheric conditions, varying road surfaces,
individual driving habits and vehicle usage, additional
or more frequent maintenance may be required.

Reporting safety defects
For USA
If you believe that your vehicle has a defect
which could cause a crash or could
cause injury or death, you should immediately
inform the National Highway Traffic
Safety Administration (NHTSA) in addition
to notifying NISSAN.
If NHTSA receives similar complaints, it
may open an inv ...
