Neutral Safety and Back-up Lamp Switch

Print

The neutral safety switch used in the 42LE automatic transaxle is called a Manual Valve Lever Position Sensor (MVLPS).

This sensor interprets the position of the manual valve inside the valve body. The information gathered is sent to the transaxle control module.

This sensor provides starting in P and N positions and also operates the back-up lamp circuit.
