JK Evap relocation

(1/2) > >>

RD Slyter:
I noticed this has been up for a week or 2 and no threads posted yet so I figured I'd get it started.

Topic is opting to relocate the Evap sensor vs. buying and installing a skid plate on 07-11 JKs. Its entirely up to you what you decide to do, but should you figure as I did that relocating is better, this thread will walk you through the how to, and what you need to do it right.

The process is simple, and takes less than 20 minutes start to finish.
You will need;
Approximately 4' of  5/8" ID rubber hose cut into 2, 2' sections (I used washer hose which is nice and thick and very flexable but can also withstand heat)
5 or 6 good sturdy zip ties
4, 1 1/4" hose clamps
Rivet gun and rivets
Drill with a 1/16" bit
9/16 and 1/2 socket and wrench
Flat tip screwdriver
Second set of hands to hold things up

To start, remove the rear seat and carpet from the back of the jeep. Next remove the existing hoses from the sensor, taking care to remember which one connects where. Since theres only 2, this shouldn't pose much of a problem. Then using a 9/16 socket wrench, unbolt and remove the sensor mounting bracket. This will release the sensor allowing it to drop. Then seporate the sensor and bracket.
Next, with the 1/2" socket, unbolt and remove the E brake line support bracket which is located just forward of the muffler in that big open space directly under the rear seat. (This is where the sensor is going to be relocated to.)
Position the sensor bracket you removed earlier ruffly centered over where you just removed the E brake line retainer (Really, anywhere will do but this kinda centers the system in the open space under here)
Using your drill, set holes into the floorboard corresponding to the existing holes in the bracket used for mounting it to the vehicle. Then, having someone hold the bracket for you, climb into the jeep and set rivets into the holes you just made, fixing the bracket to the vehicle. Then mount the sensor to the bracket. Note, you will notice the E brake lines kinda in the way. Allow them to rest on the sensor as they are not going anywhere.
Next, replace the 2 large hoses going to the sensor with the 2 longer pieces of hose you just cut, and secure them with the hoseclamps. (Routing the hoses may require a little creativity but seriously, if you feel you will have trouble here, you probably shouldn't be undertaking this project in the first place) Finally, using the zip ties, secure the hosing in such a way as to keep it from resting on the exhaust.
There you have it. Easy button pushed.

Trail Duty:
Nice write-up Ryan, thanks! Beginning to lean towards the relocation rather than the skid, seems cheaper and more effective. So the Jeep didn't throw any codes after the relocation? I've heard that can happen.

Mine is relocated rather than skid plated.
