Normal Operation
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. DTCs P0705, P0706, P0707, P0708, P0709, P1702, P1705 and P1921 cannot be set by an incorrectly adjusted selector lever cable.
