P2800 - Transmission Range Sensor B Circuit (PRNDL Input)
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
P2800 - TRANSMISSION RANGE SENSOR B CIRCUIT (PRNDL INPUT)
| Description: | The powertrain control module (PCM) checks the gear selector position by monitoring two independent voltage signals from the transmission range (TR) sensor. The TR voltages are then compared to an allowed voltage range for each gear. The test fails when the compared voltages are out of range. This DTC indicates that one TR signal is more than one band away from the majority. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Monitor the TR_A1 and TR_A2 sensor voltage PIDs. The TR_A1 sensor voltage has a negative slope, and TR_A2 sensor voltage has a positive slope. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST TA . | ||
