The P0846 fault code refers to a problem with the Transmission Fluid Pressure SensorSwitch ‘B’ Circuit RangePerformance.

This code is set by the Transmission Control Module (TCM) when it detects that the signal from the sensorswitch is not within the factory specifications.

The Transmission Fluid Pressure SensorSwitch is responsible for monitoring the pressure of the transmission fluid. It helps the TCM make adjustments to ensure smooth shifting and optimal performance. When the sensorswitch is not functioning properly, it can lead to issues with the transmission, such as harsh shifting or slipping gears.

If you receive the P0846 fault code, it is important to have your vehicle inspected and repaired by a qualified technician. They will be able to diagnose the exact cause of the issue and make the necessary repairs to restore proper functionality to your transmission. Ignoring this fault code can lead to further damage and potentially costly repairs down the line.

What are the possible causes of the p0846 fault code and how can I visually inspect them?

If you’re experiencing the p0846 fault code with your vehicle, you may notice that the Engine Light is ON or the Service Engine Soon Warning Light is illuminated. This fault code is typically caused by a faulty Transmission Fluid Pressure Sensor/Switch ‘B’, an open or shorted harness for the sensor/switch, or a poor electrical connection in the circuit. To visually inspect these possible causes, check the wiring harness and connectors related to the sensor/switch. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.

How can I determine if the Transmission Fluid Pressure Sensor/Switch ‘B’ harness is open or shorted?
