Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The input speed sensor (ISS) and output speed sensor (OSS) are hall-effect type sensors. The sensors receive supply voltage from the transmission control module (TCM) and produce a fixed amplitude square wave signal with a frequency proportionate to transmission gear rotations.
