P0843 allison transmission code.

This information allows the ECU to determine the correct shift pattern based on the current driving situation. The TFPS sensor relays this information to the ECU through a voltage signal. A P0872 DTC means that this voltage signal is unusually low, which can signal a problem with either the sensor or the hydraulic pressure.The diagnostic tool will show PS2 PRESSURIZED when PS2 is open and PS2 EXHAUSTED when PS2 is closed. DTC P088B can be caused by: 1. Restricted Main Filter. NOTE: Change both main and lube filters if main filter is restricted. 2. Low lockup pressure. 3. Open or high resistance in W118 or W158 in chassis harness.Wrap Up. To fix the P0848 fault code, start by visually inspecting the wiring harness and connectors. Look for any damage or corrosion. Check the Transmission Fluid Pressure SensorSwitch ‘B’ for any issues. Make sure the circuit has a good electrical connection. Look out for broken, bent, pushed out, or corroded pins on the connectors.The PCM/TCM receives this voltage signal to determine transmission operating pressure or when a shift is occurring. This code is set if this input does not match normal operating voltages stored in the PCM/TCM's memory. P0878 is typically an electrical circuit (TFPS sensor circuit) issue. This cannot be overlooked in the troubleshooting stage ...
