p07be transmission park position sensor switch a b correlation

P07BE Transmission Park Position Sensor Switch A B Correlation

Code: P07BE
Description: Transmission Park Position Sensor/Switch A/B Correlation
Definition: This code indicates that there is a correlation issue between the signals from the transmission park position sensor/switch A and B. The vehicle’s powertrain control module (PCM) has detected that the signals from these sensors do not match or are out of expected range when compared to each other.

Typical Severity: Moderate

Common Causes

Common Causes:

Common Misdiagnosis

OBD2 Code: P07BE

Description: Transmission Park Position Sensor/Switch A/B Correlation

Common Misdiagnosis: Replacing the transmission control module (TCM) without verifying sensor/switch wiring or connections.

Common Diagnostic Steps

OBD2 Code: P07BE

Description: Transmission Park Position Sensor/Switch A/B Correlation

Check for any technical service bulletins (TSBs) related to this code for your specific vehicle make and model.
Visually inspect the transmission park position sensor/switch wiring and connectors for damage, corrosion, or disconnection.
Use a scan tool to check for other related codes that might indicate an underlying issue with the transmission system.
Test the voltage and ground signals at the transmission park position sensor/switch using a multimeter to ensure they are within specifications.
If equipped, use a diagnostic scanner to monitor live data from the transmission park position sensors/switches A and B to verify their operation and correlation.
If necessary, replace or repair faulty wiring, connectors, or components associated with the transmission park position sensor/switch.
Clear the OBD2 codes and perform a test drive to see if the code returns. If it does not return, it may have been an intermittent issue resolved by addressing loose connections or minor faults.
