Transmission Range Sensor B Circuit (PRNDL Input)

Where it lives

For P2800, the circuit described runs through the sensor. The description of P2800 reports a fault at the sensor.

Check these first

• An open or short in the transmission range sensor B (PRNDL input) circuit
• A corroded or loose transmission range sensor B (PRNDL input) connector
• A failed transmission range sensor B (PRNDL input)
• A misadjusted gear selector linkage

What to do next

1. Read transmission range sensor B (PRNDL input) state on a scan tool
2. Move the selector through each range and watch the readout
3. Test the transmission range sensor B (PRNDL input) circuit for open and short faults
4. Check the transmission range sensor B (PRNDL input) connector pins
5. Replace the transmission range sensor B (PRNDL input) if the readout does not match the selector
6. Clear the code and retest
