What is the fault code for the EVAP system?
Some of the common fault codes associated with the EVAP system are as follows: P0440 code means that a leak has been detected or the vapor pressure sensor in the fuel tank has malfunctioned. One indication might be a faint odor of gasoline originating from the gas tank.
How can I tell if my EVAP system is working?
If the check engine light illuminates you won’t know if it’s the EVAP system or something else until you identify the fault code. To get that code you can go to an auto parts store or take your car into the dealer. Some of the common fault codes associated with the EVAP system are as follows:
When to perform an evaporative emission ( EVAP ) service bay test?
⇒ If the evaporative emission (EVAP) I/M System Status indicator displays NO, perform the EVAP Service bay test if available. ⇒ If the EVAP Service bay test is NOT available, it may take up to 6 drive cycles, with up to 17 hours between drive cycles, for the EVAP I/M System Status indicator to transition to YES.
Why is the EVAP monitor on my OBDII not working?
Upon hooking up my OBDII scanner I see that the EVAP monitor is the only one left still under pending not complete status. So seems like the dealer either reset the codes (which there was none) or disconnected the battery just to replace the door handles. Well I didnt know so thats why the emissions is failing.
How do you pass the OBD-2 emissions test?
To pass an OBD-II emissions test, a vehicle must: If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run.

What are the most common failed emission test codes?
Small leaks easier to find, because to create a vapor-like smoke the machine heats the mineral oil, it may contain dye of UV leak detection. Cycle the purge solenoid and other EVAP self-test can be run using a professional level scan tool which have a bidirectional communication ability. 1. Low Fuel Pressure
