What P081C means
P081C concerns the input 'park position' – the P contact of the selector or shift module, or the park pawl feedback – which controls switching off the ignition, key release, starter release and the 'not in park' warning. It is documented on the 2017–22 Jeep Compass with the nine-speed automatic: a 2022 bulletin lists P081C with the MIL on, with 'Vehicle not in Park' shown although P is engaged; the car cannot be switched off, modules stay awake and the battery drains. The cause was shift module software, fixed by reflashing. The check is a circuit or plausibility test of the P signal against the range sensor; no thresholds are published.

Symptoms of P081C
- 'Not in park' message although P is engaged
- Ignition cannot be switched off, battery drains
- Check engine lamp (Jeep)
Common causes of P081C
- Most likelyShift module software (Jeep Compass)
- PossibleP contact or selector switch faulty or misadjusted
- PossibleSelector cable misadjusted
- PossibleWire or connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P081C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 1C | The exact fault in that area. |
What to do next
- Note P081C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P081C
What does P081C mean?
P081C means "Park Input Circuit". P081C concerns the input 'park position' – the P contact of the selector or shift module, or the park pawl feedback – which controls switching off the ignition, key release, starter release and the 'not in park' warning. It is a generic code, so it means the same on every make.
Is it safe to drive with P081C?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P081C fail an emissions test?
P081C is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P081C to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P081C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
