I think you may be confusing terms -
Up through 1989 (cars with LH 2.2), there was a pressure transducer/sensor and an overboost switch. The transducer is connected to the APC system, and a failed one will cause a chattering APC solenoid. The overboost switch is tied to the fuel injection system, and a failed one will cause a no-start or sudden-death scenario.
Starting in 1989 (cars with LH 2.4), the overboost switch was eliminated, and its function integrated with the fuel injection computer.
Hope this helps...
