Jeep Cherokee Evap System Diagram

The Jeep Cherokee Evap System Diagram is a great way to see how your Jeep’s evaporative emission control system works. This diagram shows you the parts of the system and how they work together to keep your Jeep running clean and emissions-free.

The Jeep Cherokee is a compact SUV that was first introduced in 1984. It was originally designed to be a smaller and more fuel-efficient alternative to the full-size Jeep Wagoneer. The Cherokee quickly became one of the most popular SUVs on the market, thanks to its combination of off-road capability, comfort, and style.

Today, the Cherokee is still a popular choice for those looking for an SUV that can handle both city and country driving. And while it may have been eclipsed in recent years by newer models like the Jeep Grand Cherokee, it remains an excellent option for anyone in the market for a reliable and capable SUV. One important system on any vehicle is the evaporative emission control (EVAP) system.

This system captures fuel vapors from the gas tank and stores them in a charcoal canister until they can be burned off by the engine. A properly functioning EVAP system is essential for keeping harmful vapors out of the atmosphere and preventing potential “check engine” light issues. If you’re considering purchasing a Jeep Cherokee or are already owner, it’s important to be familiar with the EVAP system and how it works.

To help you out, we’ve put together this quick guide to the Jeep Cherokee EVAP system diagram.

How Do You Diagnose an Evap Leak?

There are a few ways that you can diagnose an EVAP leak. One way is to check the engine for any vacuum leaks. If there are any, then they will need to be repaired before proceeding.

Another way is to use a smoke machine to check for leaks in the EVAP system. This is done by attaching the smoke machine to the EVAP system and running it through all of the components. If there are any leaks, then they will show up as bubbles in the smoke.

What Happens When Evap System Fails?

The EVAP system is designed to prevent fuel vapors from escaping into the atmosphere. The system consists of several parts, including a charcoal canister, purge valve, and pressure sensor. When the engine is running, the purge valve opens and allows fresh air to enter the canister.

This causes the charcoal to absorb the fuel vapors. The pressure sensor monitors the pressure in the canister and sends a signal to the computer when it gets too high. If the system fails, it will cause one or more of these symptoms:

1) Check Engine Light: The check engine light will come on if there is a problem with any part of the EVAP system. 2) Fuel Odor: Fuel vapors may be released into the atmosphere, causing a strong fuel odor. 3) Poor Fuel Economy: The engine may run leaner than normal due to vapor leaks, resulting in reduced fuel economy.

4) drivability problems: A failed EVAP system can cause drivability problems such as hard starting, stalling, and hesitations during acceleration.

Is It Ok to Drive With Evap Leak?

No, it is not okay to drive with an EVAP leak. An EVAP leak can cause your car to run less efficiently and can also be dangerous. If you have an EVAP leak, you should take your car to a mechanic and have it fixed as soon as possible.

What are the Parts of an Evap System?

An EVAP system is made up of four main parts: the canister, the purge valve, the pressure sensor, and the vent control valve. The canister stores fuel vapors that are created when gas is evaporated in the tank. The purge valve opens and allows these vapors to be drawn into the engine where they are burned.

The pressure sensor monitors the pressure in the system and sends a signal to the computer if it gets too high. The vent control valve controls how much air flows into the system.

2001 Jeep Cherokee Fuel Vapor Tube

When it comes to your 2001 Jeep Cherokee, the fuel vapor tube is an important component that you need to be aware of. This tube helps to keep fumes and vapors from entering the cabin of your vehicle, which can be a health hazard. If this tube becomes damaged or cracked, it will need to be replaced as soon as possible.

Here is some detailed information about the fuel vapor tube in your 2001 Jeep Cherokee: The fuel vapor tube is located between the fuel tank and the charcoal canister. Its purpose is to prevent fuel vapors from entering the cabin of your vehicle.

If this tube becomes damaged or cracked, it can allow fumes and vapors into the cabin of your vehicle. This can be a health hazard for you and your passengers. If you notice any damage to this tube, it will need to be replaced as soon as possible by a qualified mechanic.

2000 Jeep Cherokee Evap Canister

The 2000 Jeep Cherokee has an evaporative canister that is located under the hood, on the driver’s side. The canister is responsible for storing fuel vapors and preventing them from entering the atmosphere. When the engine is running, the canister purges these vapors into the engine to be burned off.

If there is a problem with the canister or its components, it can cause fuel vapor leaks and reduce engine performance.


If you’re looking for a Jeep Cherokee evap system diagram, you’ve come to the right place. Here at AutoZone, we carry a wide selection of diagrams that can help you get a better understanding of your vehicle’s inner workings. In particular, our Jeep Cherokee evap system diagrams can show you how this important system works to keep your engine running smoothly.

The evaporative emission control (EVAP) system is responsible for preventing fuel vapors from escaping into the atmosphere. It does this by capturing and storing fuel vapors in a charcoal canister, which is then purged when the engine is running. If your EVAP system isn’t working properly, it can cause all sorts of problems, including decreased fuel economy and increased emissions.

That’s why it’s important to make sure everything is in good working order. And our Jeep Cherokee evap system diagrams can help you do just that.
