Contour Enthusiasts Group Archives Forums General Troubleshooting finally got my codes

ok i finally went to the auto parts store (advance) and i thought id get one or two codes boy was i wrong. So i am going to post them on here and what it says it is. so here we go.:
dtc p0401 camshaft position sensor a - bank one circut malfunction
dtc p0401 egr flow insufficient
dtc p0175 system too rich
and the one im worried the most about:
dtc p1519 intake manifold runner stuck closed.
That is what i have, can someone please help me and clue me in on what these things mean, and especially what the last code means and what i have to do to fix it. Thank you.

Bad camshaft position sensor or wiring.

Bad DPFE or clocked passages.

Caused by the other codes.

Broken IMRC cable - need new IMRC.

the IMRC what exactly is that? and where will i be able to get a new one and will it fix any of my other problems? and how do you clean your intake manifold?

FWIW: Most of these things are easily searched.

The IMRC (Intake manifold runner control) controls the secondary butterfly valves within your lower intake manifold (LIM)

When driving, and reacing an rpm of 3700 (3200@WOT) the secondary plates are rotated open to allow an increase in LIM volume, creating a surge in horsepower (you can feel that "kick" when you accelerate at those rpms.
The IMRC is the unit responsible for actuating those linkages via a cable (like a bike brake cable). Heatsoak usually kills the transistor within the silver IMRC box (located underneath the plastic cover that says "duratec" on it). Your problem is likely a failed imrc (dead due to heat), or a broken cable between that silver box, and the LIM itself.

Intake manifold cleaning can be done one of two ways:

the "on the car method" is a great method to "maintain" the cleanliness, but performed on a never-before-cleaned intake, it wouldn't do much good.

the other method is the complete rebuild, which involves pulling the UIM (upper) and LIM (lower) from the engine. It is NOT that hard, and both ways (whichever you should decide) are well documented under theduratec maintenance forum, in the duratec maintenance faq.

ok cool i think i got it now, is there something that i can check myself on that or do i just need to go to the dealership and have them replace it for me? and does anyone know how much that costs?

For sure, you can try the suck test for the EGR DTC P0401

You can manually rev the car (via the TB) to the IMRC opening point and watch for the cable to pull the secondary linkages open. The secondary linkage can be seen directly below the TB.

Another option, and a highly likely one, is that the plastic bushings that hold the linkage to the secondaries has shattered (very common...) I suggest doing a UIM/LIM teardown, and while doing so, if there is anything wrong with secondary operation OTHER than a fried IMRC, you will easily see it.

wow so prettymuch tear it apart huh? im sure i can get it all apart but im not too sure about getting it cleaned and puting the new gasket on there, that might be the only problem for me being that im not all that mechanically inclined. i will look at the cable also, i am definitely going to look for the rubber bushings as well. thanks for the help if i get more questions i will be sure to post them.
