Transmission Range Sensor A/B Correlation

Where it lives

For P2805, the part to look at first is the sensor named here.

Check these first

• Range sensor A and range sensor B disagree on selector position
• One transmission range sensor out of adjustment
• A faulty range sensor A or range sensor B
• A wiring fault between one range sensor and the module
• Low battery voltage skewing both range signals

What to do next

1. Read range sensor A and range sensor B live data together
2. Check battery voltage and charge it if low
3. Inspect both range sensor connectors and wiring
4. Check the installation and adjustment of both range sensors
5. Replace the range sensor that disagrees
6. Clear the code and retest
