How do you diagnose an EVAP leak?

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.

A leak within the system can impact how well your vehicle starts and stays running. Any issue with interrupted internal combustion may cause your engine to stall or refuse to start altogether.

The cause could be anything from a hard to find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, or compression problems. A leaking EGR valve can cause a random misfire and act like a vacuum leak.

Can you smell an EVAP leak?

One of the most obvious signs that you are facing an EVAP leak is the smell of fuel. The gas you put into your vehicle is liquid, but it becomes a gas form in the system, creating many fumes. The smallest fault in the EVAP system can allow a vapor leak that creates a noxious odor.

What are the signs of a vacuum leak?
