Transmission Park Position Sensor/Switch A/B Correlation

Where it lives

For P07BE, the description names the sensor as the part involved.

Check these first

• Park position sensors A and B disagreeing on the gear
• A dirty or worn park position switch
• A loose or corroded switch connector
• A chafed wire in the sensor A or B circuit
• A park position switch installed or adjusted wrong

What to do next

1. Read park position switch A and B states together on a scan tool
2. Cycle the gear lever through every range and watch for a mismatch
3. Inspect both switch connectors for corrosion or looseness
4. Test the sensor A and B wiring for opens and shorts
5. Replace the park position switch if the two signals will not agree
6. Clear the code and retest
