Purpose
The seat track position sensor detects the front and back positions of the driver seat.
Function
The seat track position sensor converts the seat position into an electrical signal and sends it to the SAS control module.
Construction
The seat track position sensor consists of a hall element (semi-conductor) and a magnet. The sensor converts the effect of the magnetic flux (produced by the magnet) on the hall element, into an electrical signal.
The seat track position sensor installed on the driver-side seat rail.

Operation
If the driver’s seat is slid forward, the seat track position sensor will separate from the metal plate installed to the seat slider.
When this occurs the magnetic flux of the sensor changes and that change is sent as an electrical signal to the SAS control module.
The SAS control module receives this signal and determines that the driver’s seat has been moved to a forward position.

Fail-safe
Function not equipped.

1. Connect battery positive voltage to air intake actuator terminal B (or C),
connect terminal C (or B) to ground, and then verify that the air intake actuator
operates as shown in the table.
If the operation condition is not normal, replace the air intake actuator.

Camshaft Position (CMP) Sensor Removal/Installation
CAUTION:
When replacing the CMP sensor, make sure there is no foreign material on
it such as metal shavings. If it is installed with foreign material, the sensor
output signal will malfunction resulting from fluctuation in magnetic flux and
cause a deterioration in engine control.
