Re: my 2008 Jeep Patriot Limited 2.4L 4x4. It was a bit sluggish starting after sitting a few days and engine light came on right away. The code was P2016. I kept clearing it and it came back immediately. After driving awhile it stayed off. Then right after monitors were set for emissions the engine light came on but this time it was code P2008 only. What would it be? Could it just be the battery throwing false codes?

I have worked on just about all makes and models for most of my career, but I have now been working at a Toyota dealership for the past 3 years.

to check for that P2016 code I would start by checking for power and ground at the manifold flow control valve, there should be 5 volts getting to the valve on the Brown/Light Green wire.

also for the p2008 code this is showing that the same manifold control valve is not operating the valve inside the intake runner.

It is most likely that the valves inside the intake runners are stuck or binding, this is a common problem, and it seems like Jeep has an entire intake manifold assembly to help fix this problem.

P2016 so far stayed off. Is it since the battery charged up a bit while driving?

for the 2008?

If needed... a New intake from dealer is expensive. Is there any after market ones?
Jeep Mechanic: nelson freitas,

I am not sure if that is the correct part, but before you purchase that I would recommend removing the old one and turning the rod that it is attached to to see if the valves that are controlled by that are stuck.

There should be aftermarket ones available. I know I have replaced the same manifold on another 2.4 before. I just dont remember where we got the part from.
