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).
What P07BE means
P07BE is a generic OBD-II powertrain code in the transmission group.
- Check engine light
- Usually on
- Emissions-related
- No
- Limp mode possible
- Not typical
- Drive cycle to clear
- Not required

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
Common causes
- 01One of the two sensors drifting outside toleranceMost likely
- 02Mis-adjusted shift lever mechanismPossible
Can I drive with P07BE?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P07BE
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P07BE. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P07B2, P07B8. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Park position sensor A, Park position sensor B) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: One of the two sensors drifting outside tolerance; mis-adjusted shift lever mechanism. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P07BE FAQ
What does P07BE mean?
P07BE means “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 P07BE serious? Can I keep driving?
We rate P07BE as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P07BE?
The most common causes, from most to least likely: One of the two sensors drifting outside tolerance; Mis-adjusted shift lever mechanism. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P07BE?
Typical labor is about $100–$440 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P07BE myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P07BE clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
