Use any DIY smoke tester at your own risk. Use a low-pressure gauge and regulator to prevent damage to the system. Besides dealing with flammable vapors, excessive pressure can also damage EVAP system components, leading to higher repair costs.

Professional smoke test machines cost upwards of $600, which is out of the realm of DIY auto repair, and the author wasn’t even able to find this available as a rental. At the same time, it’s also either the most expensive or bravest method of doing to. Smoke testing is the best way to test the EVAP system.Smoke Test – The idea behind the smoke test is simple, blow smoke into the EVAP system and look for smoke escaping from a compromised valve, seal, tube, or hose.The vacuum gauge will show whether the valve is holding pressure or not, and you can manually power valves to check their operation and sealing. Unpowered, the purge valve should be closed, and the vent valve should be open. Hand Vacuum Pump – A hand vacuum pump can be used to check some EVAP system valves, without the need for the engine to be running.If there is engine vacuum, this means the purge valve is stuck open. With the engine running and the purge valve solenoid electrical connector disconnected, check for vacuum in the EVAP system – there should be none. First, verify engine idle vacuum is around 21 in. Vacuum Test – All EVAP systems lead to the intake manifold, so an engine vacuum gauge can be adapted to test valves and lines for integrity.The only problem is, because we’re looking for vacuum leaks, it can be nearly impossible to find EVAP leaks without special equipment.

Refer to a repair manual to help you localize the EVAP leak. įor each YMM, these leak problems can often be localized depending on the code. You Can Use an Engine Vacuum-Pressure Gauge to Check for EVAP Leaks.

If the EVAP system detects a problem, it will illuminate the check engine light and store a diagnostic trouble code (DTC) in system memory. The test circumstances vary, depending on YMM (year, make, and model), but usually include parameters such as fuel level, vehicle speed, engine run time, or engine temperature. Other systems use a dedicated pump to run a similar test, but usually when the vehicle is not running. Some systems use a vacuum/pressure sensor to detect when vacuum is in the system and how long it’s able to hold it.
Depending on the model, the EVAP system can test itself for leaks using different strategies. The EVAP system, to work most effectively, should be completely sealed, including the fuel cap, tubes, valves, canister, and fuel tank.

A series of valves regulates the flow of air and vapors into the system, the general idea being to route them to the engine to be burned. The charcoal canister is filled with activated charcoal, whose huge surface area readily absorbs fuel vapors. Tubes connect various parts of the fuel system, such as the fuel filler tube, fuel tank, and engine intake, to the charcoal canister. Check Engine Light On? Check Your Gas Cap, First!.
