15. Pressure Sensor Failure

W-2WAY ECO-i SYSTEM Control Functions

This system contains 2 types of pressure sensors: a high-pressure sensor and a low-pressure sensor.

(1)High-pressure sensor failure

Alarms are emitted when the high-pressure sensor becomes an electrical open-circuit or a short-circuit condi- tions, and a broken wiring, short-circuit or poor connection to the PCB in the high-pressure sensor circuit.

(2)Low-pressure sensor failure

Alarms are emitted when the low-pressure sensor becomes an electrical open-circuit or a short-circuit condi-

tions, and a broken wiring, short-circuit or poor connection to the PCB in the low-pressure sensor circuit. 1
