Maxxforce EGR issues

EGR slow flow. Spot levels high

[@menardoabada5234]

What do you use to wash the parts?

[@carlton997]

Hi. I'm working on a 2015 International prostar maxxforce 13. The dtc is low egr flow. Would you say that it has a bad valve or gummed all up and needs a good cleaning? The dealership replaced the egr valve, cooler, and all sensors in late 2018.. it's my friends truck and he does not have tons of cash to throw at it for a dealership to guess at the parts. Thanks for your advice and great videos. I am a instant sub

Carlton Griffin If you could send me a screen shot of the code and also, do u guys have access to a scan tool/laptop. I would like to know how some sensor are doing. You can email me a [e-mail].

Hey carlton I’m having the same issue. Jist wondering what did you find? Thanks

[@carlton997]

@@supreetdhillon9665 I know this was a little while ago. He was right in the video. We pulled every part out and took our time to clean every part as best as we could so far so good. Thanks for a great video it sure helped

I have a question if the coolant gets inside the engine through the EGR cooler the same time your coolant gets dirty too ? I did a oil analysis for my 2012 DT466 the results came back high levels of coolant in the oil, I'm getting little bit of white smoke also my coolant is really clean but the same time I'm losing little bit of coolant.

[@JoesBusBarn]

Coolant in the oil can only be an oil cooler issue (or a major head gasket). Egr cooler would cause coolant loss. It would be blown out the exhaust pipe

[@Batman-on6gn]

@@JoesBusBarn but don't that make your coolant dirty also ? coolant is looks clean. Even though the oil analysis came back high levels of coolant in the oil, Still oil looks clean. This the COMMENTS from Blackstone Laboratories Unfortunately, this oil is heavily contaminated with coolant, which shows up in our testing as high levels of potassium and sodium. Inspect this engine carefully, and keep oil change intervals to 1,000 miles or less to help mitigate buildup until the source of the contamination can be found. Aluminum and iron are also high compared to DT 466 averages (which are based on oil run for ~6,400 miles), showing extra wear at the pistons and steel parts like the cylinder liners and rotating shafts. No fuel dilution was noted present. Check back to monitor.

I have maxxforce 2011 engine , the problem is the exhaust brake is always on and after 5min driving code SPN 3936 fmi 0 show up and the engine loose power I’ve replaced PDF sensor 2 times the problem still on

Hello came across your video and was wondering if you could give some tips on tackling some codes we have om our truck in regards to the EGR SPN 2659 FM 21 Egr mass flow rate SPN 2791 FMI 14 EGR valve control SPN 3251 FM 21 Aftertreatment 1 DPF differential pressure SPN 132 FM 0 Mass air flow SPN 596 FM19 Cruise control switch enable switch As far as cruise control i dont understand why there is a code the cruis control works good

[@JoesBusBarn]

What is the model of your unit.

[@simplyklean]

@@JoesBusBarn its a 2015 international durastar has the maxxforce in it

[@JoesBusBarn]

Sounds like you might have quite a bit carbon build up on your egr and crossover. Have you tried anything on that unit. Like regens or replaced any parts. This is my email. I can email you my number. It be easier to try and diagnose. Or we can try it over this platform. Whichever suites you better. [e-mail]

[@bandalosebanitos2175]

Hello. I purchased a 2013 AC 3000 Shuttle Bus (100k miles) (maxxforce 7) and i notice clouds of black smoke when starting to accelerate. Once it gets running it runs great and no smoke, but coming from complete stops is the issue. Could this video be a solution to this problem? We recently replaced a FRP sensor (has not asked for a regen since) and i feel like its probably why it had all this soot buildup. I am scared of being stopped and fined. Pls help if u can (p.s. i am in texas)

[@JoesBusBarn]

Yes. EGR could be the cause of your issues. Would be easier if you could give me the codes that the unit has stored in the ECM. You can pull those codes without a scanner. Email me at [e-mail]

[@terrellscaife2411]

So do you think the 2008 Max force 11 is a good reliable engine With 170,000 miles

[@juangomez8186]

Hello my friend I have a question my egr cooler is bad because I have cooling fluid consumption if I don't replace the egr cooler and I just keep adding cooling to reservoir this action will damage something ??

[@JoesBusBarn]

Hey there Juan. I would say replace that cooler at ur earliest convenience. If u prolong it. It could cause damage to DOC and DPF. We have ran units for maybe a week (driver doesn’t report issue) and have been lucky so far. But I wouldn’t recommend driver ur unit for to long adding coolant. I’m assuming that ur using about a gallon every other day. Or is it worse.

[@juangomez8186]

@@JoesBusBarn thanks for the time the you take to advise me .I using 1/2 gallon every 2 days I been watching one of your videos when you replaced erge cooler but I not sure if will be the same process on my maxxforce dt 9 because that's the only problem right now I fixed the intake heater following your instructions thanks for that also

[@travissingletary4237]

I have a 2010 international 4300 losing power up hill check engine like goes in and out. Had DPF cleaned professionally but still no power. One active code SPN 1209 FMI 9. Could that sensor cause all these issues?

[@JoesBusBarn]

Hey there Travis. Yes. The EBP exhaust back pressure sensor can cut back your power. Check the connector before replacing the EBP. The pigtails are about 60% of the problems.

[@JoesBusBarn]

Hey Chris. I’m assuming your unit (2014) has a Maxforce DT. Would need a bit more info on issue so that I can try and help you pin point the cause.

[@juangomez8186]

I have a 2014 maxxforce dt whit code 729 FMI :18 intake heater sensor that sensor is located on that part the you are cleaning on the video ??

[@JoesBusBarn]

The intake heater element is the bent up (accordion like) webbing and the the one you are inquiring about is bolted behind the aluminum case. Wire from element runs right to it. I don’t have a picture of it to show you but it’s on the case where the heating element is mounted onto.

[@juangomez8186]

@@JoesBusBarn thanks but do you think if I do the cleaning and do the same that you did the code will disappear???

[@JoesBusBarn]

It will if the heating element were to be covered in soot or bent a bit out of shape. If the code persists. You might need to replace the control unit bolted on the case on the outside of the intake. It’s something I would try. You will see the condition it’s in when you remove the upper intake (plenum)

[@juangomez8186]

@@JoesBusBarn thanks so much you are the only person who says something good about this maxxforce engines question: my engine is consuming antifreeze I replaced the reservoir cap is not visible leak what do you think will be the problem?

[@JoesBusBarn]

Hey Juan. If your loosing coolant and there are no apparent leaks. We can suspect that your egr cooler is at fault.

[@gf8848]

Where you located

[@JoesBusBarn]

Hey Geraldo. I’m in Rio Grande City. South Texas.

[@JoesBusBarn]

Hey there Edward. Cost varies depending on where you take it. You are looking at about a 10 hr job. I do this for clients (out of the school district) for 550. I know dealer is way more expensive. It’s not that hard to do if you want to do it yourself. Just be careful when pulling out EGR valve. 2 out of 3 break. Just take your time and apply lubricant when extracting. Any ? Feel free to comment or email. I’ll be happy to assist you in what I can.

Yes. Torque them down to 22 foot pounds.
