Riviera V6-3.8L SC VIN 1 (1995)
Ride Height Sensor: Description and Operation
DESCRIPTION
The height sensor controls two circuits, compressor relay coil ground circuit and exhaust solenoid coil ground circuit. To prevent energizing the
compressor relay and exhaust solenoid circuits during normal ride motions, the sensor circuit provides a predetermined delay before the ground
circuit is completed. The sensor electronically limits compressor run time and exhaust solenoid energized time. This limit function is necessary to
prevent continuous compressor operation in case of a system leak or continuous exhaust solenoid operation. This timer is reset whenever the
ignition is turned Off and On, or height sensor exhaust or compressor signal changes. The height sensor is mounted to the body frame in the rear of
the vehicle. The sensor actuator arm is attached to the control arm by a short link
