Transmission Range Control B Position Sensor/Switch Circuit Range/Performance

Where it lives

For P27F0, the part to look at first is the sensor named here.

Check these first

• A transmission range control B position sensor reading that does not match the selector position
• A transmission range control B position sensor out of adjustment
• A failed transmission range control B position sensor
• A corroded transmission range control B position sensor connector

What to do next

1. Read transmission range control B position sensor on a scan tool in each selector range
2. Compare the transmission range control B position sensor readout to the selector position
3. Test the transmission range control B position sensor signal circuit for added resistance
4. Check the transmission range control B position sensor connector pins
5. Adjust or replace transmission range control B position sensor if the readout does not match
6. Clear the code and retest
