Details of the Dodge p0861 OBD Code

Dodge fault code P0861 relates to the transmission control module detecting an issue with the gear shift module.

Dodge OBD code P0861 means that the Transmission Fluid Pressure (TFP) Sensor Switch C Circuit is Range/Performance.

This code is triggered by the Powertrain Control Module (PCM) when it detects that the voltage signal from the TFP sensor switch C is not within the expected range or performance level.

The TFP sensor switch C is typically located inside the transmission and is responsible for monitoring the fluid pressure within the transmission.

It sends voltage signals to the PCM to indicate the pressure levels.

When the PCM receives a signal that is outside the expected range or performance, it triggers the P0861 fault code.

In summary, OBD code P0861 on a Dodge vehicle indicates an issue with the Transmission Fluid Pressure Sensor Switch C circuit, where the voltage signal is not within the expected range or performance level, as detected by the PCM.

Mechanic’s Tech Notes

Detailed information on Dodge fault code P0861, which relates to the transmission control module communication circuit.

To diagnose and fix OBDII code P0861 in a Dodge, start by checking the transmission control module (TCM) power and ground using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) using a scan tool.

If the TCM does not respond, reprogramming or reflashing may be necessary.

Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.

This thorough inspection can help identify and address the root cause of the P0861 code.
