P081D

DTC P081D, sometimes indicated as P081D00 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 neutral input circuit.

This code is set when the PCM detects a problem with the neutral input circuit. This circuit monitors the position of the shift lever and sends a signal to the PCM indicating when the vehicle is in neutral.
Possible causes of this code include a faulty shift lever sensor, a wiring problem, or a failed PCM.
If this code is present, check the shift lever sensor and wiring for damage or faults. If no problems are found, replace the PCM.
