What P0814 means
P0814 concerns the drive or data circuit of the range display – the PRNDL or PRNDM display or lighting on the selector, sometimes in the instrument cluster. It is documented on the 2017–22 Jeep Compass with the nine-speed automatic: the electronic shift module stores P0814 with the MIL on, the selector lighting flickers or goes dark, and in a 2020 bulletin the lever could be moved out of park during cranking so that the engine stalled. The cause was software in the shift module, fixed by reflashing; a 2022 bulletin adds P081C. A wrong or missing range display matters for safety because the driver cannot reliably see P, R or N. No thresholds are published.
P0814 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0814
- Range display on the selector flickers or stays dark
- Check engine lamp (Jeep)
- Lever can leave P during cranking, engine stalls (Jeep)
Common causes of P0814
- Most likelyShift module software (Jeep Compass)
- PossibleConnector or wire to the selector display or cluster
- PossibleDisplay LED or selector module faulty
- Less likelyRange sensor or transmission module delivering an invalid range
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0814 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. |
| 14 | The exact fault in that area. |
What to do next
- Note P0814 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 P0814
What does P0814 mean?
P0814 means "Transmission Range Display Circuit". P0814 concerns the drive or data circuit of the range display – the PRNDL or PRNDM display or lighting on the selector, sometimes in the instrument cluster. It is a generic code, so it means the same on every make.
Is it safe to drive with P0814?
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 P0814 fail an emissions test?
P0814 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 P0814 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0814 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
