How does the evaporative emissions system detect a leak?
If there is a leak, the system either will not achieve a vacuum, or a vacuum cannot be maintained. Usually a fault can only be detected after a cold start with a trip of sufficient length and driving conditions to run the needed tests. The enhanced evaporative system diagnostic conducts sub-tests in order to detect the fault conditions.
What does DTC p0446 stand for on an EVAP system?
If the vacuum value is too high, a malfunction is indicated by setting DTC P0446. This tests for small leaks to the intake manifold. This is accomplished by sealing the EVAP system purge valve and the EVAP vent valve and allowing the PCM to monitor the FTP sensor. The FTP sensor value should not increase.

How does a wideband O2 sensor work?
Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).
