Fuel Tank Pressure (Pa)

The value indicates the calculated tank pressure. The Engine control module (ECM) calculates the average pressure with the help of the measured power consumption on the leak diagnostic unit's pump. The pressure will rise from 0 Pa to approx. 4500 Pa during the test.

HINT: The calculated pressure can differ from the measured pressure by ±15 %. This is normal.
