Default P0107 after timing belt change

I completed a timing belt change late last night on my 05 Sedona 3.5L. During the course of the change I lost the clip for the MAPS sensor. It is currently attached as best I could get it by some ingenious Zipties. I am about to start calling to track down a new retaining clip for the wiring connector.

When I first start the engine it is super smooth but after about 3/5 seconds it starts to run rough. I can drive it and get up to 75-80mph on the highway but I do not have the power I am used to. Is this loose connector a likely culprit?

I didn't replace spark plugs saving that for next weekend when I have a new set of valve cover gaskets coming in since they are leaking.

Thanks for any thoughts or input.

P0107 - Manifold absolute pressure sensor Low Input

Open or short to ground between MAPS and ECM
• Open between MAPS and ECM
• Open between MAPS and ground
• Poor connections between MAPS and ECM
• Misplaced, loose or corroded terminals
• Foreign materials fouled MAPS
• Faulty MAPS

I would definately check the connector first, also make sure that the terminals inside the connector are tight.

Thanks for the input, I have pulled the codes and looked them up. Just wondering if that connector not being secured the way it was designed could be causing the symptoms I am experiencing.

Thanks

That could be the problem. But, like I said, also make sure that the terminals in the plug are tight. I have seen where a terminal will come loose inside the plug therefore giving you a poor connection.

Just got done talking to a dealer parts department. Evidently they don't sell the small metal spring loaded retaining clip just the complete engine wiring harness......

To the salvage yard I will go this afternoon unless anyone has any thoughts on someplace online I could find a replacement clip.
