Rear Propshaft Speed Sensor

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

The transfer case shift control module converts the pulsating AC voltage from the rear transfer case speed sensor to a rear propshaft speed in RPM to be used for calculations. The rear propshaft speed can be displayed with a scan tool.
