P07BE on Cadillac by model: symptoms, diagnosis and fix
A faulty park-position switch inside the electronic shifter assembly intermittently fails to signal that the vehicle is in Park. This produces a persistent 'Shift to Park' message on the driver information center even when the lever is physically in Park, and the vehicle may refuse to fully power down, staying in accessory mode and draining the 12V battery overnight. Owners report shifter codes such as P07BE and P26C8. GM addressed the concern with TSB 19-NA-206. This is an electronic-shifter/electrical failure, separate from internal transmission shudder/harsh-shift issues.
Common Symptoms
- 'Shift to Park' message stays on with lever already in Park
- Vehicle will not fully shut off / stays in accessory mode
- Dead 12V battery overnight from failure to power down
- Shifter error codes P07BE / P26C8
- Intermittent refusal to shift out of Park
How to Fix
Per GM TSB 19-NA-206 the repair is often installing an in-line jumper harness (P/N 84733196) at the shifter connector; where that does not resolve it, the shifter assembly is replaced. Replacement requires removing the center console trim and generally needs no special programming. Pressing the Park button squarely in the center can be a temporary workaround for the dual-sensor design.

What are the most common causes of P07BE?
The most common causes of P07BE are: One failing park position sensor/switch (A or B), Misadjustment of one switch, Wiring/connector fault on one circuit, Corrosion causing offset readings, Faulty TCM. The specific cause varies by vehicle.
