Transfer case speed sensors — checking functionality and replacement (Chevrolet Trailblazer 1)

The transfer case has three speed sensors. The first sensor is located on the front secondary shaft, and the second on the rear. The third sensor is the vehicle speed sensor, which sends signals to the PCM. The third sensor is also located on the rear secondary shaft of the transfer case. All three sensors are variable resistance sensors that produce alternating voltage signals. As the speed increases, the frequency and magnitude of the alternating voltage of the sensor signal increase proportionally.

The procedure for checking the performance and replacing the transfer case output shaft speed sensors is basically similar to the procedure for the vehicle speed sensor. Refer to the chapter section "Vehicle Speed Sensor - Replacement".
