read that page in the FSM. on P2006,
and do what it says.
same answer for all cars,
it tell you what tests to do to find the cause.
try alldata.com , log in and read what it says;.
the PCM can set that for 2 reasons.
1: the IRMC is bad.
2: the vacuum reading on the engine or so out of wack. this test lies.
this might be under the 8year, smog warranty, did you check?
what it does is , give better low end torque. so, its no show stopper.
in a real jeep shop, the attach their scan tool and tell it to cycle the
IMRC solenoid, and if it moves, then it must be some other cause.
if it dont move, they fix that. (wires bad, or solenoid)
one thing people dont understand is that most cheap scan tools
(like used in most autozoned) do not let you see all OBD2 DTC codes
there are many, codes, it seems yours is scanning right.
P2. is a factory only code.
so got other codes thrown?
or other symptoms, like bogging or misfire, or??????
also nobody can tell you what you can do.
we dont know your skills or tools ? or many other facts.
this code means the feed back signal says it didnt move, or did not move fully.
that is why not having factory tool makes this hard.
check connections, test the MFV. by hand. test the solenoid by hand.
if all these check out, then we scan the system looking for all other sensors reading funny.
here is the FSM page .
Intake Manifold Runner Control Stuck Closed
Number of Trips to Set Code: 1
Trouble Code Conditions:
The Powertrain Control Module (PCM) detects that the position feedback of the Manifold Flow Valve Position Sensor is not within range of the adapted value learned during in-plant initialization or after a non volatile memory reset (adaptive memory clear).
Possible Causes:
- * 5 volt supply circuit open or high resistance, shorted to voltage, ground or another circuit
- * MFV signal circuit open or high resistance, shorted to voltage, ground or another circuit
- * Sensor ground circuit open or high resistance
- * Manifold flow valve
- * Intake manifold
- * PCM
