Pressure sensor, EVAP (585) - B204L only

/ 900 / 1998 / 2. Engine / Evaporative Emission System ORVR OBD II / Technical description / Pressure sensor, EVAP (585) - B204L only

A differential pressure sensor is mounted on the tank. It compares the pressure in the tank with the barometric pressure.

The pressure sensor is powered with 5V from the electronic control module.

Depending on the pressure difference between the tank and the atmosphere, a proportional voltage is sent from the pressure sensor to the electronic control module.

When there is no pressure difference, the voltage from the pressure sensor is approx. 2.5 V.

The pressure sensor is used for OBD II-diagnostics.
