There will be a total of 4 speed sensors on an Envoy or Trailblazer. One in each front hub and one in the rear axle. These three are for the ABS system and sense individual wheel speeds. Then the 4th one is located at the tail end of the transmission or transfer case if its 4wd and is the main vehicle speed sensor. This is the one the PCM uses to control engine and transmission functions.
