Conditions for Setting the DTC

WARNING: This page is about a different variant/trim than selected.

The EVAP system is not able to achieve or maintain a calibrated level of vacuum less than 2.74kPa (11 in H20) before a calibrated amount of purge volume has passed through the system.
After setting the DTC for the first time, 2L (0.5gal) of fuel must be consumed before setting the DTC for the second time.
With a DTC P0455 detected a weak vacuum follow-up test (fuel cap replacement test) will run and pass if tank vacuum is greater than 2.74kPa (11 in H2O). This test will run for a maximum of 21 min. This test runs until it passes.
