Hey guys!

The check engine light just came on yesterday, after hooking it up to a OBD reader i managed to scan the code P2009 - intake manifold runner control circuit low bank 1.

After a bit of reading on the forum i know this issue regards the APV in one way or another. Problem is i am having a hard time locating the APV motor and the connector to it. The plan is no clean the connection to the APV and hope its works, because i dont know how easy it is replacing the APV motor?

Any help or pictures is very much appriciated!

Yes i got the same code so i changed the acuctor and the APV and i also ran seafoam but it still was coming up so idk what to do anymore

I got the same code, I was reading the the acutor goes bad so i changed it and I also APV to the open position, however it did erase code p2004 but not the P2009 and I ran seafoam threw it but the code is still on please LmK

p2009 is an electrical problem. Either the circuit to the solenoid is damaged or the solenoid itself has gone (which is not uncommon). You may want to change all 3 intake valve solenoids while you're back there (and plug it all back together correctly)

^^Let’s not end up with both of you in the ditch ...

P2009 is for low voltage on the APV motor. There is no solenoid; it’s electrically pulse-modulated by the pcm and it has nothing to do with the other vacuum/solenoid actuated intake valves.

then what do you think it is?

if you’re lucky the wiring connector to it is maybe loose or not fully seated

might need a new APV motor

but could be a broken wire or short

worst case the ecu has an internal circuit problem, but most unlikely thing to happen

this is from a 2005 Model Year service manual:

It's a new apv motor it might be a short the the wiring harness then I'm going to have to trace it down then
