Sensor Assy., Angle
The internal potentiometer utilizes a spring-loaded brush system moving across a resistive track to report drum position. Thermal cycling causes the sealing O-ring to shrink, allowing moisture to enter and oxidize the contact surfaces. This creates inconsistent resistance readings that the PCM cannot reconcile, leading to shift interruptions and error codes.

Gear Position Switch
This switch provides the discrete ground signals required for the PCM to identify the exact gear engaged. If the internal copper contacts become fouled or worn, the PCM will not receive the 'confirmation' signal of a successful shift, often resulting in a blinking 'N' or a display of '--' even if the angle sensor is functioning correctly.

Shift Motor Sub-Harness
The low-voltage signals from the angle sensor are highly sensitive to resistance. Pin fretting and corrosion within the intermediate connectors of the sub-harness cause voltage drops that the PCM interprets as sensor malfunctions. Replacing the harness section ensures signal integrity between the logic controller and the electromechanical actuators.
