Transmission Position Switch/Sensor: Description and Operation
AODE-W Transmissions
Manual Lever Position (MLP) Sensor
Manual Lever Position (MLP) Sensor
DESCRIPTION
The manual lever position (MLP) sensor sends a signal to the PCM assembly, which indicates position of the shift lever (P, R, N, D, 2, 1). The
MLP sensor is located on the outside of the transmission on the manual lever shift.
PURPOSE
The Manual Lever Position (MLP) sensor provides an input signal to the Powertrain Control Module (PCM), notifying the PCM of the current
transmission shift lever position.
OPERATION
The PCM applies a 5.0 volt reference signal to the MLP circuit pin 30. SIG RTN circuit pin 46 supplies a ground path to the sensor. As the
transmission is shifted the MLP output wiper arm moves to a corresponding resistor connection. The six inline resistors provide a separate voltage
drop for each transmission position.
