Diesel Engine
The vehicle speed sensor is mounted on the front of the rear axle housing above the pinion flange. The speed sensor ring is located in the rear axle between the ring gear and differential case. The signal from the sensor is not routed directly to the powertrain control module (PCM). It is received by the Programmable Speedometer/Odometer Module (PSOM), which provides the PCM with a vehicle speed signal.
