Ford 6.7L Power Stroke Diesel :: Location Of Air Intake Of Cabin A/C System?
Jun 29, 2013
Where the air intake for the cabin air conditioning system is? The past several trucks I've owned had a cabin air filter which I replaced annually. They get filthy and I can see why this dirt should not get into the evaporator coil. It will reduce air flow and here in Texas we need all the air flow we can get (106 today). It shouldn't be too hard to improvise a filter to wrap over the intake (for a cheap fix).

How can I tell if my truck has a cabin filter and where would it be located? I looked through the OM but it was little to no luck....

My truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.

my egr delete j pipe orings give me trouble and i replaced but broke a bolt, now i think that big donut oring is leaking, i was reading you can put a 3/4 freeze plug in to eliminate any coolant into the intake, where does the freeze plug go,front cover or intake and does coolant still pass thru the j pipe?

I just replaced the oil/egr cooler, stand pipes and dummy plugs along with all suggested upgrades, just filled with oil hooked up batteries and while filing with coolant it started gushing out from under the intake in front. I think I see an o-ring pushed out.. I hope I can lift the intake without removing the turbo!!!

I was chasing down a P2074 CEL and thought it was a stressed wiring harness connection on the MAF.
Took it to the Ford house and they chased it for 2 days, believing it was the MAF and air filter. They told me that air filter was allowing to much air in. My thoughts was, that is was what MAF is for, to regulate the fuel based on how much air was going in.
I just found out that they are stating that an AFE dry air filter contributed to a cracked intake manifold because the aftermarket air filter made the intake get too hot.

Anyways, I've been doing a lot of work on my 6.0 2004 Ford Excursion lately, and recently installed my Sinister Diesel intercooler pipes and intake elbow, and had to remove my throttle body completely to do so. I know that the 2004 models throw codes when removed, and that's what I'm here for. Mine isn't dogged down and actually runs even smoother with my new piping and intake, but I want to get rid of this code.
Is there any tune out there that can erase it? For some reason my Edge Insight CTS2 sees the code, but my SCT X4 flash tuner doesn't see the P0488 code. I know people have discussed this topic several times, but after hours of reading through posts I never found any solution to this. All I need is a way to delete the code because I don't like having my CTS2 with a trouble code for something I did on purpose!

I understand that exhaust runs through the EGR. what I don't know is:
Does the EGR valve control the amount of exhaust into the air intake?
If so, does only the amount of exhaust let through the valve go through the EGR?
if so, if the EGR valve is closed then no exhaust will go through the EGR?

I I have a pretty good o ring leak where the egr cooler meets with the intake. My question is can i replace the o ring without removing​ the intake. If so what is the process.

Sunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).
After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.
My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?
Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?

I need to remove my EGR valve to clean the unit of carbon. While there I will be removing the intake elbow to check if I have the throttle plate installed on my engine. What the part number is for the gasket / o-ring that seals the elbow to the intake manifold??

Under light acceleration without any load. The motor backfired through the intake. Lost all boost. Other than the backfire noise the motor seems to be fine except for lack of power due to no boost. The motor has been serviced by Ford Dealer since new. All services have been done at 5K mile intervals. The last service was done at 60K miles. All filters had been changed at that time (oil, air and fuel).
I do have experience with turbo/ supercharged motors. My experience would tell me that the problem was with a lean condition at the time of the backfire. Plenty of fuel in the tank and no low fuel pressure warning. I have seen low fuel pressure warning in the past but it happened during the winter when temps were negative 40 degrees. The truck is still under extended warranty so I really don't have concerns regarding repair costs.

was looking for the oil pressure sensor and can't find it got it narrowed to 2 there is a sensor between the the oil filter and fuel filter i think thats the temp sensor and then there's 1 at the say 11 o'clock position behind the the oil filter...both have a 2 pigtail connector.

I have recently bought a 04 f250 6.0, and it has the intake thumping noise that varies speed with idle... I was told it could be a broken rocker, a bent push rod, or a broken roller... I am not that much experienced with diesels. I've spoken to the dealership, and they don't wanna fix it, they said it wouldnt hurt it to drive it like that, but the noise bothers the hell out of me, and everyone notices it. so i wanna get it fixed. I am hoping its just a rocker. if it is just a rocker how deep am i in? truck has 240xxx miles on it, and runs perfect other than that noise.

I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

My 2003 f250 6.0l just up and quit. It make a popping noise out of the intake when cranking. I am getting 1150 psi at the icp and ipr is at 62% which seems high to me. The FICM voltage seem fine unless the batteries are drained and I am getting FICM sync. I replaced the HPOP, ICP sensor and IPR about a year ago. I recently replaced the air conditioning compressor and power steering pump. I am at a bit of a loss. I did pull the IPR and everything looked fine.

I've had a 2007 Coachman Freelander class C RV with E-450 for about 8 months now. We have been on 7 camping trips to the same location this summer, and the engine has sputtered in exactly the same place on 6 of these trips. It's pretty freaky, like the road has bad mojo there.
We have to come down a steep incline for about 2 miles, dropping about 500' vertical at about 6500' elevation. Then we drive for 2 miles on the flat before hitting a big mountain climb up to 7500'. About 30 seconds into the climb, the engine will sputter, and kick out smoke from the tailpipe. The first time I pulled over, and it idled fine. I took off and climbed the hill just fine. Now I just drive through the sputter, and it goes away after a minute.
So what's happening? Is the fuel tank sloshing crud around? I never get a water-in-fuel alarm, although the E450 doesn't have much of a message center. It doesn't happen on other sections of mountain road. This rig has about 38,000 miles, and is bone stock. I put new oil and fuel filters in before the summer. This rig is the same size as my old '82 RV E350 w/ 460, and boy is the 6.0L an improvement!

just picked up a 2004 (May, 04) F350 DRW with the 6.0 Powerstroke. I love this truck so far. After sitting in the driveway overnight, I noticed a decent sized puddle of oil on the driveway, probably the size of my fist. I took several pictures for diagnosis:
Any quick thoughts as to where this oil leak is originating?
