As a Range Rover owner, I’m sorry to say that I’m pretty familiar with the brand’s occasional reliability issues.

One of the most frustrating problems I’ve encountered is the EVAP leak fault P2407.

If you’re reading this article, chances are you’re experiencing the same thing, and I feel your pain.

What models are affected?

Signs and symptoms

The EVAP leak fault P2407 is related to problems with the evaporative emissions system on Range Rovers.

This system is designed to capture and dispose of fuel vapors that would otherwise be released into the atmosphere.

Some common signs and symptoms of an EVAP leak fault P2407 include:

• Check engine light is on
• Fuel tank is difficult to fill
• Fuel odor inside the car
• Poor fuel economy

List of possible OBD codes

If you’re experiencing an EVAP leak fault P2407, you may also encounter other OBD codes. Here’s a list of codes that are relevant to this issue:

Common causes

There could be a few different things causing your EVAP leak fault P2407. Here are some common causes:

• Bad gas cap: A loose, damaged, or missing gas cap can cause pressure issues with your fuel system, leading to an EVAP leak fault.
• Bad EVAP canister: The EVAP canister is responsible for storing fuel vapor. Over time, it can become packed with dirt and debris, leading to a leak.
• Bad EVAP leak detection pump: This pump helps to pressurize your fuel system and detect leaks. If it’s not working properly, it can lead to an EVAP leak fault.
• Bad gasket or seal: A cracked or damaged seal between your fuel tank and the EVAP system can cause a leak.
• Broken or kinked EVAP line: This is a less common issue, but a kink or break in your EVAP line can lead to a leak.
