ISSUE:
Beginning with Job 1 1997, some vehicles will be equipped with a new Digital Transmission Range (DTR) sensor. The DTR sensor is located on the
outside of the transmission (Figure 1) at the outer manual lever.
ACTION:
Refer to the following text to properly diagnose a concern with the DTR sensor.
The new DTR sensor completes the start circuit in "Park" and "Neutral," the backup lamp circuit in "Reverse" and the neutral sense circuit (4X4 only) in
"Neutral."
The DTR sensor also opens/closes a set of four (4) switches that are monitored by the Powertrain Control Module (PCM) to determine the position of the
transmission manual lever.
