Anyone have this error before? Anything I need to worry about?

TIA

Mine threw a code a little while ago, I cleared it, and it didnt come back in 30 miles of driving, but I decided to replace it week ago in order to be on the safe side. You need the sensor, an o-ring, and a clip - about 25 dollars total at the dealer. The job itself is a half hour job (you have a 2.8 right?). It is located in the back left of the engine behind the cylinder bank and underrneath the palstic flexible hose that connects the airbox to the intake manifold. You take this part off, and the sensor is about 6 inches below it. You pull the clip to the rear and then pull the sensor out. My sensor was kind of stuck in place, so it took some wiggling. Install is the opposite. the ony tricky part is that space is kind of tight down there. Also, make sure your engine is completely cold before you try this otherwise you will get burned.

Thanks for the info, this is my third time seeing it, so I think I'll replace mine also. (2.8 yes)

might as well, its a cheap and easy fix which is rare.

Can you elaborate more on where this thing is, I picked the stuff up today, but now cant find where it goes, lol. The dealer was telling me on the drivers side....??? the sensor is green, w/ a little nipple on the end, also got the clip and o-ring, only cost like $7 though, he checked the part w/ the vin #.
TIA

Yes, it's hard to see. It's almost like you need to feel around for it. As was said, on the passenger side, near the firewall. Get a flashlight and maybe a step ladder so that you can see from above a little better. Although I forgot to do this, it is best to bleed a little of coolant first. Otherwise, because it is pressurized, a little coolant will shoot out when you remove the sensor. Fortunately, my coolant was only lukewarm, but still gave me a little shower. Also, go slow, make sure you don't drop the little pin that you have to slide out to free up the sensor. Once you find it, as long as you have relatively small hands, shouldn't be too difficult. After I found mine, it was only probably 5-10 minutes max to swap it out.

I think I found it, but my hands are way to big to get in there, did you guys have to take the part of the intake that attaches to the actual engine? Does the piece have to square like clips on it?

Yes, you do need to remove part of the intake boot to get in there. It's just two brackets to take off, no biggy.

what he said. it takes a little creativity to figure out how to get your hands there, but it can be done.
