Transmission Inputs

Transmission Range Sensor 

DPS6 is range by wire with mechanical Park. DPS6 uses a dual PWM output (at 250 Hz) TRS where one signal is the inverse of the other and the sum of the two signals add up to 100%. Each signal is tested for frequency errors (P0706 / P2801), duty cycle out of range low (P0707 / P2802) and duty cycle out of range high (P0708 / P2803). There is also a correlation error (P2805) if the two signals do not add up to 100%.

Speed Sensors 

Input 1 Speed Sensor (I1SS) - detects input shaft 1 speed, connected to clutch 1 and the odd gears (1st, 3rd and 5th). I1SS is tested for power supply faults (P06A6), circuit failures detected by the TCM hardware (P0715), erratic signal (P0716), and lack of signal (P0717).

Input 2 Speed Sensor (I2SS) - detects input shaft 2 speed, connected to clutch 2 and the even gears (R, 2nd, 4th and 6th). I2SS is tested for power supply faults (P06A7), circuit failures detected by the TCM hardware (P2765), erratic signal (P2766), and lack of signal (P2767).

Output Speed Sensor (OSS) - detects output speed. OSS is tested for power supply faults (P06A8), circuit failures detected by the TCM hardware (P0720), erratic signal (P0721), and lack of signal (P0722).
