the imrc is located on the front of the motor under a plastic cover it should be a gray box with a cable coming out of it and will have a 5 wire plug
The imrc on a 2002 Mercury Cougar with the V6 Duratec is located just in front of the engine under the plastic IMRC cover, the plastic cover which says Duratec. There should be several screws holding the cover in place.
The intake manifold runner control (IMRC) is beneath the plastic IMRC cover, which is held on by several screws.
The actuator assembly of the IMRC system is attached to the cylinder head/intake manifold, just up of the water pump.
The IMRC is held in a metal box in front of the engine. It is covered by the plastic thing, called the IMRC cover by ford. There should be three or four bolts holding the cover on.
It is located to the right of the serpentine belt, left of the intake manifold, directly above the water pump. It has two rods coming out of it and it electric controlled, not vacuum.
Since you are asking, I assume you have a V6 Duratec powered contour. If this is the case, the IMRC is located just in front of the engine, underneath the IMRC cover, the plastic cover mounted to the engine with several screws and says "Duratec" on it.
Possible problems:Faulty Intake Manifold Runner Position, Sensor, SwitchHarness for IMRC loose or shortedMechanic Binding, Seizure, or Broken IMRC
I a guessing that you have a V6 Contour. The P1519, means that the Intake Manifold Runner Control(IMRC) solenoid is not moving when commanded by the PCM. The PCM knows it is not moving, becaus there is a built-in position sensor inside of the IMRC. The job of the IMRC is to shorten or lengthen the air flow passages into the intake manifold at the right times for maximum performance, by opening and closing ports inside of the intake manifold. These passages are moved by a cable attached to the IMRC that moves butterfly valves on shafts that run through the center of the intake. You can see the cable which will be attached to a lever and a shaft by looking right below the throttle body assembly on the driver's side of the engine. Follow that cable, and you will find the IMRC. It may even be bolted to the top of the front valve cover. Cances are you need a new IMRC. But you should clean the air intake manifold with carb cleaner to free up the butterfly valves I described. Sometimes what makes those IMRC assemblies fail in the first place, is heavily carboned up intake runner valves that cuse undue stress on the IMRC.
It is located on the backside of the intake manifold. You have to remove the upper intake manifold to get to it. A common problem I have been told by a couple of mechanics is that if the wiring harness has been undone and reconnected before, that the harness could be draped over the top of the imrc rod, preventing it from moving. Also, it is common that the imrc will get clogged up with gunk and flushing it out with a intake cleaner sometimes will free it up and fix the problem. I had to replace a bushing on my right IMRC actuator rod yesterday. I did not remove any part of the intake manifold. I used a mirror and a flash light to see the part. I had to put tape around my finger sticky side out to hold the bushing as I could only get one finger back there. I used a coat hanger with a hook bent in to it to pull the control rod up into place. It was tough, but the bushing is replaced and everything works fine now. Hope this helps
Check engine lite thru a computer read out says IMRC is stuck. I started it this spring after 5 months sitting and lite stayed out for 19 minutes
Under the intake manifold on both sides
Its under the front valve vanity cover.
