DTC P081C, sometimes indicated as P081C00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing park input circuit.

This code is set when the PCM detects a malfunction in the park input circuit.
Possible causes of this code include a defective park/neutral switch, a defective shift interlock solenoid, or a defective park/neutral position switch.
