Most cars use vacuum to test for leaks in the EVAP system but some actually use pressure instead such as dodge BMW and Subaru, thereвЂ™s a pump that forces air into the tank and then sensors tests for the ability of the EVAP system to hold pressure. Many times the valve gets open or closed, and to fix your problem all you have to do is replace the valve. The vent valve is one of the most common problems with the EVAP system because itвЂ™s usually right under the car and exposed to all the elements. The fresh air prevents buildup of the vacuum and keeps the system pressure balanced. As explained before the EVAP system also needs a fresh air source, so the vent valve is opened up when the tank pressure sensor shows that thereвЂ™s a vacuum on the fuel tank. The fuel vapor gets stored in a vapor canister and when the right conditions exist the computer opens up the purge valve and allows the fuel vapors to be sucked into the intake and burned during the combustion process. It has a liquid vapor separator to block out any liquid fuel from getting. The vent that goes up the middle of the tank is what pulls the fuel vapor out of the gas tank. Instead, the ESIM uses two weights, a diaphragm, and a.

Unlike previous Leak Detection System, the ESIM does not contain a solenoid. The red sensor is the tank pressure sensor which tells the computer if the tank is pressurized or under vacuum. The Evaporative System Integrity Module, also known as an Evaporative System Integrity Monitor or ESIM, is a key component of the EVAP System on many late model Chrysler, Dodge, Jeep, RAM Trucks, and Fiat vehicles. So you have to have 1/2 tank +/- 1/4 tank for it to run. If its older than 2001 then you can have 2 not ready reading. NJ DMV Inspection center allow 1 not ready reading if your car is year model 2001&up. Less than 1/4 tank can affect the accuracy of the sensors and the test. For anyone who is reading this thread here is some updates and solid information.

A full tank (more than 3/4) will disable it because of the likelihood of sucking fuel into the system if the purge valve is opened. We have the fuel pump on the left of fuel tank which feeds the gas to the engine through the fuel lines, on the right we have the gas cap which seals the fuel tank, the most common causes for an EVAP check engine light. You have to have around 1/2 tank of gas for the Evap monitor to run.
