Transmission Range Control Valve Switch
WARNING: This page is about a different variant/trim than selected.
The transmission range control valve switch is a linear hall effect sensor that changes current flow based on magnetic field position relative to the sensor. The transmission control module (TCM) supplies a 9 V reference circuit to the transmission range control valve switch. Sensor signal circuit is an input to the TCM. The sensor signal circuit toggles between 0.8V and 2V based on valve position.
