DTC Advanced Diagnostics: P0717: General Description

The mainshaft speed sensor is built into the transmission. The mainshaft speed sensor generates different frequency pulse signal depending on the rotating speed of the gear on brake B1. The pulse signal is transmitted to the transmission control module (TCM) and used for measurement of the input shaft speed. When there is a missing pulse while the input shaft is rotating which occurs by open circuit, intermittent open circuit, and short circuit, the TCM detects as a malfunction. When the rotation speed measured by the mainshaft speed sensor is a specified value for a set time, the TCM detects a malfunction and stores a DTC.
