Transmission Position Sensor/Switch: Testing and Inspection

Manual Lever Position (MLP) Sensor

C180-MLP Sensor:

Schematics:

Component Testing Procedure:

The powertrain control module (PCM) sends a voltage signal to the manual lever position (MLP) sensor. The MLP sensor incorporates a series of step-down resistors which act as a voltage divider. The PCM monitors this voltage which corresponds to the position of the manual lever. The MLP is located on the outside of the transaxle at the manual lever.

Transmission Function: Determine desired gear and EPC pressure.

Symptoms: Harsh engagements and firm shift feel. No 3/4 shift. May downshift to a lower gear.

DTC's: 634, 522 (two digit) codes. Refer to Manufacturer Code Charts
