Ford 6.7L Power Stroke Diesel :: CEL With Code P2074 - Cracked Intake Manifold?
Mar 11, 2014
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.

Having trouble with this code. Replaced stock air filter with aFe filter 10,000 miles ago. 20,000 on truck. Threw code sunday dealer replaced filter with stock. said code may come back. which it did 5 miles later.
Edge CTS says max boost is at 22 psi. Is this something i will live with or indication of something else?

I'm starting to get an intermittent CEL for P2074 ("Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load"). It first came on Saturday halfway into a 4 hour drive (Not towing, just driving 75mph-80mph on the freeway). I cleared the code and restarted the truck and it immediately came back on. About a half hour later I stopped for fuel, cleared the code, and it stayed off for the rest of the trip.
Got into the truck today and drove it for 10 minutes (driving around town) and it came back on. Cleared the code and restarted the truck, drove it for about a hour and it never came back on. The truck is running and driving just fine.
The truck is a 2011 F-250, all stock (except for a AFE Cold air intake that's been on the truck for a while now). The truck has about 98,000 miles.
From what I've read on other posts, it might just be a mass air flow sensor? Should I just replace that myself, or pay the $100 extended warranty deductible and take it into Ford?

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.

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!

My truck threw a P2073 code. Its Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle. I do have aftermarket intake. It threw this code 2 weeks after install. Does this mean my mass air flow sensor is going to fail soon?

I have 98 windstar, p1538 code, IMRC. I have physically checked both IMRC's and they are functioning as they should. (if they were bad, they would not move at all right?) Assuming they are good, which step in the troubleshooting process I go to now? The van runs perfect, just that darn light! Do I start going for the O2 sensor now? What to next in the chain of troubleshooting?

]I am in the process of swapping my oil cooler. When i pulled the smaller cover off of the cover that goes over the oil cooler, i heard a pop. The cover, not the one that bolts onto the motor the one that bolts to that, is cracked...bad. is there a place i can get one? need to know parts illustration with numbers?

Swapped out the orange covers for smoke ones on my truck and noticed that 4 out of 5 bases have cracks at the rear end of the lights. One screw would barely hold in as the plastic around the screw was all cracked which makes the hole larger. Is this a common issue?

My husband has a 2011 GTI, which has just hit the 40k mileage mark. His CEL started coming on in March, but we figured it was due to him not tightening the gas cap enough, as he'd open and relock the gas cap, and the CEL would go away within a few restarts of the car. Took it into the stealership last week, got the 40k service (which was a bit of a rip-off in itself), and then got told the manifold was bad.
This is the exact text for the invoice: "Checked the vehicle for codes and found code P2015. Traced the intermittent failure to the intake manifold valve flap sensor failing."
I've seen a lot of posts around this problem, for many models and years, but it seems like most people managed to get it repaired under warranty / TSB. So I have three questions:
1. In the OBD codes, does it store date as well as code? In other words, is there a way to prove that this failed under 36k miles?
2. What's the process for getting this escalated to VWOA customer care, since I feel this should be taken care of under warranty?
3. The dealership we took the car to (which is not where we purchased the car, but is just closer to home) was shady, and the guy we worked with was, to say it nicely, a jerk.

My question is can a cracked injector tip let gases back in the fuel system?

This pump hangs down fairly low and appears easy for ice and rocks to hit on my 2013. Something hit mine and took a chunk out of the drain tube. No leaks yet but I am looking to get a new one and keep this as a spare, or just JB weld it. Can I just buy the lower section, or do I need to get entire pump?
Any creative protection bracket made? Would just have to take it off to change filter though. Any leak in this housing is a major show stopper when in the middle of nowhere! Maybe why it is getting brought into the tank on new models?

Some technical issues here. Had the intake manifold replaced under extended warranty ('09 2.0 TSI, 115,000km); they cleaned out the carbon as well. There were all sorts of codes it was throwing, despite having new coils and plugs installed.
One more thing to do. I still have Crank Position Sensor code showing. Car runs fine (much better now actually),but I was told if I don't get this last code looked after, one day the car just won't start.

I can't get my exhaust manifold bolts off. They are in bad shape. The 10mm is too loose and 3/8 just rounds. I have had the torches on them too! Can the bolts be cut off with a torch?? Haven't broken any. Can't get the bolt heads to move. It's an 04, original manifolds. I am working the driver's side. I can't figure this one out. How to get this manifold off?

How difficult is it to change the passenger exhaust manifold? I have just finished replacing the left exhaust manifold. The biggest issue was rusted fasteners and inexperience. Have torches. Any you tube videos show the left manifold being changed but not the right. I do not have a hoist and work in my driveway. Is the right side more difficult and should I leave it to someone with a hoist?

I have a 2011 Tiguan S 4Motion with just over 63k Miles which for the most part has been problem free and great to drive since I leased it at 40k miles. About 2 weeks ago my CEL came on and I used the Torque app on my phone to check the code and it was the apparently well known P2015 intake manifold runner position switch code. The car was running perfectly fine so I cleared the code and it stayed off for about a week before coming back on with the same fault again yesterday. I have a couple of questions for the much more knowledgeable than I people in this forum around this code.
First - I've read in several places that VW has placed an extended warranty on the manifold and fuel injectors for the 2.0 TSI and that this code is usually an indicator that the manifold needs to be replaced under this warranty. What I haven't found though is conclusive info on is whether the 2.0T in my 2011 Tiguan is covered under this extended warranty. Since this code so conveniently is popping up just 3k miles past the end of my 60K mark, I'd like to know this. I leased the car from Enterprise, not a dealer so I'm worried that whatever dealer I take it too will try to bend me over on the service so the knowledge that the manifold is still covered would be at least some comfort.
Second - I won't be able to get it in to a service department until mid next week and I have a 300 mile trip to make this weekend. The car is driving fine as far as I can tell so I'm not overly concerned. I do my own basic maintenance i.e. oil changes, plugs/coil packs etc. but I'm thinking changing the manifold would be a little bit out of my comfort zone..

Wife took truck out and turned around after going less then a mile, saying it was running very bad. We got this truck about two months ago at a state vehicle auction. It was a state used truck, 145,000 miles, 05 Ford F350, ext cab and 8' bed. Anyway at first I thought it was valve tap until research said an exhaust manifold. With a fog machine in rear exhaust pipe we confirmed it was leaking and replaced the exhaust manifold. Figured it was probably a good time to replace spark plugs too. Took truck for a ride and she still buck and farted.
Got a code machine and got P0171 and P0174. Couldn't find a vacuum leak, but your could hear the air being sucked in. went to local parts store, guys couldn't find leak, but they said truck sounded like a steam machine. today I made a homemade smoke machine and smoke came from air intake, figured the gaskets were bad. The pictures show what I saw when I took the gaskets off. The port that has melted is the same port were the exhaust manifold was leaking from. Am in deep "doo-doo". What caused this?

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?

Looking at a 2003 Prius with 77K miles. Turn the key, the engine starts, runs smooth for about 5-7 seconds. After that it starts to run rough and rattle, then shuts off. The only code I pulled was P3191. I pulled off the air cleaner to clean the throttle body, and noticed a small pool of oil in the bottom of the intake manifold. Is that normal, or could that be causing the code issue? BTW, I cleaned the MAF and throttle body, and the engine still does the same thing.
