P07BE Transmission Park Position Sensor/Switch A/B Correlation
The two redundant park position sensors A and B disagree — one reports Park, the other does not. Until the discrepancy is cleared the TCM cannot trust either reading and falls back to a safe state (typically blocking key removal and engine restart).
Is it safe to drive with P07BE?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelyOne of the two sensors drifting outside tolerance
- PossibleMis-adjusted shift lever mechanism
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
