Transmission Range Display Circuit
What it means
P0814 means there's a fault in the circuit that drives the transmission range (PRNDL) display on the instrument cluster. The transmission itself typically still shifts normally; the problem is that the gear-position indicator may read incorrectly or not at all. The usual causes are wiring in the display circuit or the transmission range sensor feeding it.
Can I keep driving? Safe to drive — this affects the gear-position display, not how the transmission works; the shown range may be wrong or blank, so fix it to keep the indicator accurate.

How to diagnose & fix
Work through it in order
- Confirm whether the transmission actually shifts normally or just displays the wrong range.
- Inspect the wiring and connectors between the range sensor, module, and cluster.
- Test the transmission range sensor signal against gear position.
- Replace the range sensor if its output is wrong.
- If the sensor and wiring are good, have the instrument cluster or module checked.
