There's four different engines. You gotta specify which one you have when asking engine-related questions.

This first one is for a 2.4L. Next is the 3.5L. By the time I got to formatting the last two, it occurred to me to put the engine size at the top left. I didn't check to see if any of these are the same. Some applications list different part numbers, but that doesn't guarantee some won't interchange.

We use AllData for diagrams and other service information. You can buy a one or five year subscription for your one model for a reasonable cost. Shops pay close to a thousand dollars per year for total access to all models. The better value for you is to find a used manufacturer's manual on eBay. They're often found for less than $30.00 - $45.00. I prefer paper myself because it's easy to add sticky notes and bookmarks, and you don't have to be online to use it.

Ya gotta make this complicated.

This drawing is different. It's for the same function on a 2008, and it's the same for a 2006 model. I double-checked, and the 2007 is definitely different.

This one does show three of the colors you listed, but those are powers and grounds which can be common to other sensors. Double-check you're on the right sensor, although there aren't any others I can think of that have five wires. You actually have two sensors in this assembly. It sits in the fresh air intake tube ahead of the throttle body.

If this drawing doesn't help, we will have to go by voltage readings to figure out which wire is for which function. I can help with that if you need me.
