Manual Lever Position Sensor

Manual Lever Position Sensor (MLPS):

PURPOSE
The Powertrain Control Module (PCM) sends voltage to the Manual Lever Position Sensor (MLP) to determine the desired gear and electronic pressure control. The MLP is located on the outside of the transmission case at the gearshift selector lever.

CONSTRUCTION
The manual lever position sensor incorporates a series of step-down resistors which act as a voltage divider.

OPERATION
When a gear is selected reference voltage is modified by step-down resistors. The PCM monitors this voltage which corresponds to the position of the gearshift selector lever (P, R, N, D, 2 or 1).

SYMPTOMS
Harsh engagements, firm shift feel.

DIAGNOSTIC TROUBLE CODES
- 67 (two digit) 634, 654,
- 659, 667, 668 (three digit).
- (Code 67 also displays if A/C is on during On-Board Diagnostic or On-Board Diagnostic run in neutral.)
