Digital Transmission Range Sensor

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2003 Mazda B4000, 2003 Mazda B3000, 2003 Mazda B2300, 2002 Mazda B4000, and 2002 Mazda B3000. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Range (TR) sensor is located on outside of transmission at manual lever. See Figure. The TR sensor opens or closes a set of 4 switches that are monitored by the PCM. The internal switch signal corresponds with position of the gearshift lever. TR sensor completes the neutral/start and back-up lights circuits. Malfunction of the TR sensor may cause harsh engagements and firm shift feel. Improper shifting or shift selection, no back-up lights, and/or no engine cranking may also result.
