2011 f250 6.7 power stroke Just had turbo coolant link replaced 4 dAys ago engine light just turned on today truck running fine?

 

what code do you have? That is usually always the first step and maybe related to the repair.

 

Thanks . I guess the first thing I should do is either buy a code reader or go to auto zone for free. Will do so as soon as possible and update. Thanks again.

 

Was driving today, and the light went off? No more cel. Truck still running great. Had a friend check for a code, and nothing? Thanks again. I will keep extra attention on it.

 

If a code is set (when the Check Engine Light (CEL) turns on) you have to go to the scanner's HISTORY option to find out what it was. The FREEZE FRAME utility will also show you precisely what all sensor data was once the code was set. Scan tools are not that expensive anymore and if the one you used doesn't have these features, it well worth an upgrade. I bring up the history and freeze frame because these are important diagnostic tools. A lot of people will disconnect the battery to clear the code. This also removes the history and freeze frame data and a technician would want to see that data to understand the issue -and also to see if it is a repeat code or was a different code. Also, clearing a CEL doesn't fix anything. The computer is only reporting bad news. It didn't create it.

Just so you know, diagnostic trouble codes (DTC) have protocols to set them and to turn them off. There are some codes that will nearly immediately set the CEL. Most have a parameter for the trouble to occur in two or more drive cycles, a duration event, or repeated event in a drive cycle before it sets a code. There will always be anomalies with an internal combustion engine. Most of these are attributable to cyclic variation. If the CEL lit every time a slight hiccup occurred, you'd be driving around with the CEL blinking like a Christmas light. So, most of the time when the CEL sets, something has occurred meeting the parameter. False triggers are uncommon. The CEL will come back once the conditions that set it initially recur.

 

well the light CEL turned back on, finally went and got a code reader. I get back code P0401. The EGR flow is insufficient. After I had the turbo coolant linkage replaced the dealer mechanic stated that i need to have the 2 fuel filters replaced and the same for the air filter. I did both of these things 6 days ago, and CEL light is back on. After putting them in I reset the fuel filter maintenance in my truck. Do I need to reset the CEL via my code reader now that the air filter has also been changed?

 

I don't see how changing filters has anything to do with a egr flow insufficient code.

 

The EGR cooler assembly needs to be replaced, is why P0401 is setting. This has nothing to do with what your mechanic did with replacing the turbo coolant line. It probably looks like what is illustrated above, is why P0401 is setting.

 

I am aware that I am ignorant to any of this, and I am most definitely not a mechanic. I mentioned the air filter only because on a different post re: the code P0401 an answer to that person was that it could be something as easy as changing the air filter to replacing the EGR. Sorry as I should have started off mentioning this. Thank you for your help.

Sadly this all started at the same time or there abouts to the Turbo coolant linkage have to be repaired. Paid over $1000 for that repair alone I feel the dealer service dept took me to the bank on this one). Not sure that I can afford to keep up with all these repairs stacked up like this.

Thanks again

 

Count your blessings that the frequency of repairs and the relative cost (emphasis on relative) have been substantially less than the repairs to the previous engines namely the 6.0/6.4L Navistar ticking time bombs. The 6.7L Ford has been overall a very solid power train, and drastic overall improvement since its introduction in 2011. The fact it still remains the diesel option for current model year trucks with very little change after now being in production for eight model years should speak for itself. By the way, this is coming from a Ford dealership technician who owned a 2007 6.0L, and decided to make the switch to my current 2016 6.7L back in July of 2015 for the very reasons mentioned above if it matters.

As far as cost of ownership goes, I'm fairly certain that any 3/4 ton pickup that is moderately used, is going to cost pretty close no matter what the brand (Dodge, GM or Ford).

Have the EGR cooler cleaned or replace it- it cost me 850 bones to have it replaced and it's warranteed

 

you can clean the cooler vs replacing. This issue centers a lot around the type of driving you do.

 

What causes the cooler to clog like that?

 

A number of varying factors. Poor fuel quality or combustion, extended idling (which would be evident with a high engine hour count to driven mileage ratio), long term short drive usage etc.

For 2015 and up models, the secondary cooling system no longer passes through the EGR cooler core, only the primary system. This, supposedly is intended to address the issue of these coolers clogging up with carbon like it appears in the picture I posted above.

 

Thanks m-chan68. I have a 2015 and I avoid idling and short runs like a plague. I always use Ford's cetane booster at every fill up. Sometimes I gotta leave my wife in the truck when I run into a store or something. She has COPD and needs the AC running. During those times, I use the fast idle setup to run it about 1200 RPMs. Hopefully, I'm doing the right things.
