before replacing the pressure switch try to jump it and create a false pressure reading. Did this on a Ford F550 once. as long as the yaris is a Normally open switch it should create the false reading.

It is not a switch, but rather a pressure transducer. To bypass it you would need to provide the correct resistance for the pressure you are trying to emulate.
