- The input turbine speed sensor is responsible for measuring the speed of the turbine shaft in the transmission. This information is used by the transmission control module (TCM) to control the shifting of the gears.
- If the input turbine speed sensor is not working properly, the TCM will not be able to accurately control the shifting of the gears, which can lead to the transmission being sluggish.
- Additionally, a faulty input turbine speed sensor can cause the check engine light to come on, as it is considered to be a critical sensor for the proper functioning of the transmission.
