Circuit description and component location
The vehicle speed sensor uses two separate coils to count gear teeth; one coil is used by the ECM to sense vehicle speed and the other is sometimes used by the OEM to feed the speedometer. This ten-page tree covers the sensor circuit. The vehicle speed sensor is installed in the rear of the transmission.
Cummins specifies a 750 to 1500 ohm coil, and a single-coil VSS used on some automatic transmissions feeds a conditioning circuit that outputs a digital speed signal to ECM pin 7; any additional load on a single coil can cause this fault. All checks are made with a Cummins service tool such as Compulink, Echek or a diagnostic tool, and inactive codes are cleared once the repair is confirmed.
Applicable truck models and engines
