Pinpoint Test C : Transmission Range Sensor

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to TRANSMISSION CONTROLS - 10R80 for schematic and connector information.

    Normal Operation and Fault Conditions 

    The 10R80 transmission uses a manual shifter to engage and disengage Park. The shifter position is detected by reading TR sensors A and B. The 10R80 transmission uses dual PWM output (at 125 Hz) TR sensors where the duty cycle of TR sensor A increases as the shifter is moved from Park to Sport and the duty cycle TR sensor B decreases as the shifter is moved from Park to Sport. Together, the sum of the two duty cycle signals should add up to 100%.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PCM P0706:00 Transmission Range Sensor "A" Circuit Range/Performance: No Sub Type Information This DTC indicates the frequency of TR sensor A is out of range (expected to be 125 Hz +/- 50 Hz). This could be caused by an open or a short in the TR sensor power or ground circuits.
    PCM P0707:00 Transmission Range Sensor "A" Circuit Low: No Sub Type Information This DTC indicates the duty cycle of TR sensor A is out of range low (less than 7%). This could be caused by an open circuit or a short to ground in the TR sensor A circuit.
    PCM P0708:00 Transmission Range Sensor "A" Circuit High: No Sub Type Information This DTC indicates the duty cycle of TR sensor A is out of range high (greater than 93%). This could be caused by a short to power in the TR sensor A circuit.
    PCM P0709:00 Transmission Range Sensor "A" Circuit Intermittent: No Sub Type Information This DTC illuminates the wrench light in conjunction with P0706, P0707 and/or P0708. Resolve the more specific DTC first.
    PCM P1705:00 Transmission Range Circuit Not Indicating Park/Neutral During Self Test: No Sub Type Information This DTC indicates the TR sensor did not show park or neutral during a KOEO or KOER self-test.
    PCM P26C3:00 Internal Control Module Transmission Range Sensor Performance: No Sub Type Information This DTC indicates TR sensors A and/or B are out of range, or the 2 sensors do not correlate.
    PCM P2801:00 Transmission Range Sensor "B" Circuit Range/Performance: No Sub Type Information This DTC indicates the frequency of TR sensor B is out of range (expected to be 125 Hz +/- 50 Hz). This could be caused by an open or a short in the TR sensor power or ground circuits.
    PCM P2802:00 Transmission Range Sensor "B" Circuit Low: No Sub Type Information This DTC indicates the duty cycle of TR sensor B is out of range low (less than 7%). This could be caused by an open circuit or a short to ground in the TR sensor B circuit.
    PCM P2803:00 Transmission Range Sensor "B" Circuit High: No Sub Type Information This DTC indicates the duty cycle of TR sensor B is out of range high (greater than 93%). This could be caused by a short to power in the TR sensor B circuit.
    PCM P2804:00 Transmission Range Sensor "B" Circuit Intermittent: No Sub Type Information This DTC illuminates the wrench light in conjunction with P2801, P2802 and/or P2803. Resolve the more specific DTC first.
    PCM P2805:00 Transmission Range Sensor "A"/ "B" Correlation: No Sub Type Information This DTC indicates both TR sensors are within range, but the sum of their duty cycles is out of range (total duty cycle should be 96% to 104%).
