Normal Operation

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The TR  sensor has a set of Hall-effect sensors that have a pattern of ON/OFF states which are dependent on the PARK, REVERSE, NEUTRAL, DRIVE, 3, 2 or 1 position of the manual valve. The TR  sensor has digital sensor (hall effect) that converts the shifter position into a bit pattern, and a micro controller that converts the 4 bit signal into a 125 Hz pulse width modulated signal. The TR  sensor also provides signals for the starting system and the reverse lights. The PCM uses the TR  sensor signal as an input for its strategy for shifting and TCC  operation. The PCM also uses the TR sensor signal for transmission fault detection and diagnostics. The TR  sensor is integral to the leadframe. DTC  s P0705, P0706, P0707, P0708, P0709, P1702 and P1921 cannot be set by an incorrectly adjusted selector lever cable.

DTC DESCRIPTION

DTC Description Fault Trigger Condition
P0705 - Transmission Range Sensor "A" Circuit (PRNDL Input) sensor This DTC  sets with DTC  P1702. The PCM sets this DTC  when it has detected the TR  sensor signal duty cycle is within range but does not match the calibrated bit pattern.
P0706 - Transmission Range Sensor "A" Circuit Range/Performance This DTC  sets with DTC  P1702. The PCM sets this DTC  when it has detected a TR  sensor signal duty cycle that is out of range.
P0707 - Transmission Range Sensor "A" Circuit Low This DTC  sets with DTC  P1702. The PCM detected a TR  sensor signal duty cycle is out of range.
P0708 - Transmission Range Sensor "A" Circuit High This DTC  sets with DTC  P1702. The PCM detected a TR  sensor signal duty cycle is out of range.
P0709 - Transmission Range Sensor "A" Circuit Intermittent This DTC  sets with DTC  P1702. The PCM detected a TR  sensor signal duty cycle is not out of range but is invalid.
P1702 - Transmission Range Sensor Circuit Intermittent This DTC  sets with P0705, P0706, P0707, P0708 or P0709, service P1702 last. The PCM detected that the TR  sensor signal duty cycle is not out of range but is invalid.
P1921 - Transmission Range Signal This DTC  sets with P0705, P0706, P0707, P0708 or P0709, service P1921 last. The PCM detected that the TR  sensor signal duty cycle is out of range.
