Details of the Dodge p0845 OBD Code

Dodge fault code P0845 relates to transmission fluid pressure sensor circuit issues.

Dodge OBD code P0845 means Transmission Fluid Pressure Sensor/Switch B Circuit.

This code is triggered when the Powertrain Control Module (PCM) detects an electrical malfunction in the transmission fluid pressure sensor/switch B circuit.

The sensor/switch B is typically located within the transmission valve body and is responsible for monitoring hydraulic pressure in the transmission.

When this code is set, it indicates an issue with the electrical circuit associated with the transmission fluid pressure sensor/switch B.

This could be due to wiring problems, a faulty sensor/switch, or issues with the PCM itself.

It is important to inspect the wiring harness for any damage or corrosion, test the sensor/switch for proper operation, and verify the PCM’s functionality to diagnose and repair the root cause of the P0845 code.

Mechanic’s Tech Notes
