I guess I should not have praised the common rail injectors on Thursday. Had a #.2 pumping injector go down . At least it wasn’t a cup issue.  If you ever get multiple injector faults check for DEF in the fuel . Lucky it was just a faulty injector this time . But we have had drivers talking on the phone/ distracted while fueling up and put DEF in the fuel tanks and eat the injectors up 

Lol, damn I always thought DEF in the fuel was an extremely expensive mistake as it pretty much destroyed majority of the fuel system. 

Let us know how you make out 

No it doesn’t, however a slight increase in throttle will speed it up some. it’s a “small engine” and can only bring in and compress so much air at once. So there is a sweet spot.

Thanks ónix just been having a lot of issues coming up with This truck getting to them one by one . I’ll order the tool and go from there . Thanks  making another post about code p0410 that came back today . 

With these trucks one issue can cause a chain of events. However it’s not just Mack/Volvo engines with problems. To be honest I think they have the least amount of issues. 

The biggest issue I have with the MPs is that if you’re gonna try and cut cost and do the work yourself you’re still gonna have to buck up to buy a lot of “speciality” tools. Even ones like this to just change a sensor. If you’re only gonna do the job once it’s pry better to just take it to the mothership, funny how that works….However I love any kind of excuse to buy a new tool!

Well it got chopped by something and that would be the gear…I’d suggest getting the depth gauge tool and a new sensor.

Three way switch. Up is latch which is  engine brake on as soon as you take your foot off of the throttle or shut the cruise off. Middle is auto and that’s when speed gets to 4mph over your set speed the engine brake comes on. Bottom is set and that’s to set the speed your engine brake comes on at. The other switch is control switch for engine brake which is off/med/hi. 

Test the boost pressure sensor (Key on/Engine off reading should be under 1 psi) Also has anyone messed with any of the parameters on this truck? 

Awesome!! Nice truck too. Love the pics, thanks for sharing. 

It’s also not a step lol

Since we are on the subject of cooling systems for these trucks and what comes out must go back in, this tool I find is a must have for any newer diesel. Any kind of air in these systems is detrimental to parts especially egr coolers. Doesn’t have to be snap on but i find this one works very well.

What would be nice if there was a section to just post useful tools for trucks with part numbers/pictures. 

Any logged codes?

We need pics bro!

Sorry to hear about your mom, 93 is a damn good age. Hopefully she pulls through. Really enjoyed the story of the doctor coming in to save the old dog. Must be pretty rewarding when you get called in to figure something out no one else can….especially when the shop forman says “hold on I know of a guy”

Damn your just a target for scammers 

Get new fuel lines too

Let me know if you need anything else. 

Did you get the truck fixed?

Anytime you replace a part you should. The 7th injector is high on the list like a turbo. 

you should
