I had my check engine light come on the other day, I scanned it at work and got the code P2016 intake manifold runner position sensor ?switch circuit low bank 1. I haven't been able to find out much about this code. any help please.
Code P2016

P2016-INTAKE MANIFOLD RUNNER POSITION SENSOR CIRCUIT LOW
When Monitored:
With the ignition on and battery voltage greater than 10.4 volts.
Set Condition:
The Powertrain Control Module (PCM) detects that the Manifold Flow Valve (MFV) Position Sensor input voltage is below the minimum acceptable value.
Possible Causes
(K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO GROUND
(K602) MFV SIGNAL CIRCUIT SHORTED TO GROUND
(K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO (K900) SENSOR GROUND CIRCUIT
(K602) MFV SIGNAL CIRCUIT SHORTED TO (K900) SENSOR GROUND CIRCUIT
(K857) 5 VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE
(K602) MFV SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE

I had that code, I replaced the runner actuator, cleared the codes and it never came back.
The actuator turns the flaps in the intake manifold and is about the size of a fist. Its easy to replace with a ratchet set(may need an extender) and the part cost around $100.
I suggest using an OEM part because I ordered a cheap china knockoff from amazon that didn't work before i bought the Mopar one.
There are a lot of posts about replacing this part so search for them if you need more guidance.

I've run into the same issue. replaced the actuator..didn't solve the problem. the actuator is getting the power (5v).
So picked up another actuator thinking the first one might be bad.
I hooked them both up and started the engine. Neither one moves.
Any thoughts on what might be causing this?

I've run into this. I also replaced my actuator, to no effect - light stays on.
The more i've been reading, the more I'm thinking (and fearing) that the manifold flow valves themselves are not working. There's a return spring that either gives up, or the plastic of the intake manifold that holds the spring, breaks. Unfortunately, you need to replace the whole intake manifold in either case.
It may also be the sensor that picks up the manifold flow valve position, but I don't know if that's a replaceable part or not yet.
Chances are, though, your electrical system is fine. The damn manifold flappers are a very common issue for the GEMA engines...

Any time you have plastic pieces on or near the manifold it seems to cause trouble! Heat and plastic are not best of friends. I had a piece on the intake on my grand marquee break...had to replace the entire intake. Good luck, hope it is something simple and painless!
