Integra LS Coupe L4-1834cc 1.8L DOHC MFI (1997)
Pressure Switch: Description and Operation
ABS Pressure Switch
PURPOSE
The pressure switch monitors the pressure accumulation in the accumulator. When the pressure in the accumulator rises, the Bourdon tube in the
pressure switch deforms outward, which in turn activates the microswitch by the force of the spring attached to the sensing lever.
FUNCTION
When the pressure in the accumulator drops due to Anti-lock Brake System (ABS) operation, the Bourdon tube moves in the opposite direction,
and the micro-switch is eventually turned off. The ABS control unit detects the fluid pressure in the accumulator by the ON/OFF signals from the
pressure switch.
