Where is the evap canister located on a 1997 jeep grand cherokee laredo 4.0

Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling the fuel tank with the engine running could conceivable cause this code as well or if the cap wasn't properly tightened. Any of the following could also be the cause:

• A small leak in any of the EVAP hoses or fuel tank hoses
• A small leak in the purge valve or vent valve
• The EVAP Canister may be leaking

ECM LOCATED EITHER LEFT FRONT FENDER NEAR THE RADIATOR SUPPORT OR LOOK IN RIGHT FRONT FENDER NEAR EVAP CANISTER.

Sounds like a bad battery to me. Turns over really slowly? Also, be sure to check your oil, this is extremely important!

not sure when a tune may have been done but that is a suggestion and cleaning the throttle body throat with some cleaner.

open hood and ck for broken vacuum hoses going to the purge valve(2 vacuum ports and a wiring connector)
on the drivers side between airbox and firewall
if good remove driver side rear tire and inspect hoses next to the gas tank and 3rd, the canister is in that wheel well also insp for cracked hoses there also, been working for jeep 12 years i charged people about 1 hour to correct this probem.

EVAP canister is located behind the left-rear wheel. It is attached to a two-piece support bracket

You should add a rs4 performance chip or the fuel economy chip also made by rs4. there like 70 bucks. If the problem is electrical changing your chip could solve the problem. Even if is doesnt work the chip will make your truck idle more smoothly, have better throttle response, and you will add 3-7 mpg. I bought one for my 1997 jeep grand cherokee straight six, and it felt like i was driving a different truck . It mae that much of a difference...you cant loose!!!Like everyone says , it could be a vac leak or a clogged fuel filter , soetimes bad gas...your problem is a needle in haystack. Try the chip...I hope this helps

You tell us Jeep Cherokee (Laredo), in a Grand Cherokee subforum? I confussed.

If this is a Cherokee, review the Repair Manual XJ Cherokee

If this is Grand Cherokee, review ths Repair Manual ZJ-Secc-8W-Wiring-Diagrams (page 7, 9 and 10 for location, details and description). The diagramas can find it in the next pages.

I hope help yuo with this (remember rated this help). Good luck.

Yes, you should replace it. This canister is to take the fumes from your gas tank into your engine. You need this to pass your state smog test.
