What Does P07BE Mean?
The transmission park position sensor/switch A and B signals do not correlate with each other. The TCM compares readings from both park position sensors and has detected that their outputs disagree beyond an acceptable threshold. One sensor may be reading Park while the other does not, or the voltage values differ significantly. This correlation fault indicates that at least one of the two sensors (or its circuit) is providing inaccurate data, compromising the dual-sensor Park verification system.
Common Causes
35%
One park position sensor (A or B) is failing or degraded producing inaccurate readings
25%
Wiring issue on one sensor circuit causing signal offset between A and B
20%
Mechanical misalignment of one sensor relative to the other on the transmission
15%
Corrosion or poor connection on one sensor connector creating resistance-based signal difference
5%
Shift cable maladjustment causing the manual valve to sit between positions differently for each sensor
Diagnostic Steps
1
Monitor both park position sensor A and B voltages simultaneously while cycling through all gear positions — identify which sensor readings deviate from specification.
2
Compare the voltage difference between sensors A and B at each position — the out-of-spec sensor will show consistent offset or erratic behavior.
3
Check for companion DTCs (P07B2-P07B7 for sensor A, P07B8-P07BD for sensor B) that may identify which specific sensor circuit has the primary fault.
4
Inspect both sensor connectors and wiring for damage, corrosion, or high-resistance connections that could explain the correlation mismatch.
5
Verify both sensors are properly aligned and mounted — if one was recently replaced or disturbed, verify correct indexing to the manual valve.
6
Replace the sensor identified as out-of-specification, clear codes, and verify correlation between A and B readings across all positions.

The most common cause of P07BE (Transmission Park Position Sensor/Switch "A"/"B" Correlation) is: One park position sensor (A or B) is failing or degraded producing inaccurate readings
Typical repair costs for P07BE range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
When sensors disagree, the TCM cannot reliably confirm Park position, which may cause no-start conditions, incorrect gear display, or shift interlock malfunctions. The vehicle may still be drivable in most cases but Park engagement verification is compromised. Always use the parking brake and schedule repair promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P07BE to identify the root cause.
