P0850: Understanding The Transmission Park/Neutral Switch Input Circuit
The P0850 fault code refers to a problem with the ParkNeutral Position (PNP) switch circuit in the transmission manual shift shaft switch assembly.
This switch is responsible for indicating the gear selector lever position to the Transmission Control Module (TCM). It is crucial for engine start enabling, engine controls, and determining transmission shift patterns. The PNP switch is integrated into the Internal Mode Switch (IMS) and connects to the TCM through a short wire harness. The TCM receives five inputs from the IMS, which represent Signal A, Signal B, Signal C, Signal P (Parity), and Signal N (ParkNeutral Start Signal).
These inputs can be displayed on a scan tool. The P0850 code is triggered when the Engine Control Module (ECM) detects that the ParkNeutral switch signal is at 0V or low while the IMS reports a Drive range. This indicates a malfunction in the PNP switch circuit.
It is important to address this issue promptly to ensure proper engine start enablement and transmission functionality.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the automobile fault code P0850.
