Agreed! Think of them as AC systems where reading the pressure gauges can tell or lead you to what's wrong internally. Same with the temp readings in aftertreatment systems. Won't tell you what the problem is, but will point you to the right direction for testing. Cheers

Hey there, I didn't test resistance. Found a bad 5v ref circuit which was the problem.

Gottcha. Would you happen to know the resistance range? Appreciate your help.

@@giff1011 sorry I don't. But if your 5vref, ground and signal circuits are good, then you have a bad sensor.

No worries. I actually have a 2009 F-150 in which the abs module needed repair. Well that repair didn’t fix the problem and come to find out my pressure transducer also failed. So I rolled the dice on a 2010 unit the because I wasn’t about to spend 5-6x more for a 09 unit. Both are 4x2 and HCU pump assembly are the same part number and bolted right in. What I didn’t know and found out last night when installed the 2010 unit is they have a brake booster vacuum sensor. The 2009 didn’t have it. So where I am now is trying to figure out the nominal resistance value of that sensor at 5v so I can modify the “new” unit into thinking I have a good sensor. I don’t have computer capable of modifying the ABS controller module otherwise I just do that. Thx again for helping and if you happen to find that number please let me know I appreciate it. Take care

@@giff1011 ah ok, can you just grab one from a junk yard truck and wire it in?

They're good engines as long as you get one 2021 and newer OR 2017-2021 with a replaced head. The older heads were faulty with bad valve seats. Other then that, not too much goes wrong except NOX IN sensors, which is common on all engines.

Very nice! Glad it helped.

Well, thank you 😊

All kinds of codes. Egr circuit issues, pulling down 5vref so all other sensors that share the vref.

That is correct!

Ooof, sorry to hear that.

What did you end up finding?

What i found was what appeared to be paper towel jammed up inside the thermo recirculation valve, had me pretty stumped for a bit because everything tested good, i pulled the line off and saw a bunch of brown paper towel jammed up inside. I work at a peterbilt dealer and the truck came back 3 times for the same 559 code.

@@ryanm6027 Great find!

Hey there, yes there are pins to test at the connector for power, ground, ignition power and datalink. There should be information available for the connector mapping if googled 👍

Thank you so much for the incredibly prompt guidance, sir. I greatly appreciate it. As directed, I found a map for the connector and checked the pins. It appears a small cracked developed in a pin, causing it to loosen. After addressing this matter, the truck ran properly. Thank you for taking time to support and direct me. It was pivotal.

That's definitely a possibility.

Hey there, I don't at the moment... will let you know if I get something like that.

Yea, sounds like you have an intermittent loss in power. Corrosion or rubbed thru wiring. If it gets worse, then you'll have to find the bad power circuit. Start with batter connections and work your way up

You are not alone.

Aiyyyyy, we still out here saving lives 😊

@@AcousticHills I’m in shock at how much water came out, overflowed one of those disposable aluminum half trays. A truly astounding amount of water

Such a loss, we will never forget...

Indeed, look away for 1 second and poof. It's the sunny days now that hurt the most 😞

So true. Even tried going in for the save... that was a hard no 😔

Hey there, Allison DOC

I probably should make one after I get a chance to play around with it more!

That's not good. Run a couple regens to try to clear it up. If it's still inverted, you have soot deposits on your doc and/ or DPF. Remove and have them cleaned. Run another regen after they're clean to make sure temps aren't inverted. If they still are, your DOC is washed and needs to be replaced.

There should be a fuse panel/ module under the passenger side carpet also, I would check that if you had water in it.

Yes it had but no major damage just little wet. Today i will check other side someone sed its can be purple wire short or coroded.

Check your power, ground and datalink to the ECM

If you're running a deleted system, youd have to see how they deleted it. EGR values would have no change on IMP because coolers are usually blocked off. Some deletes weld or remove the turbo actuators. Youd have to go back to old school methods of diag which include watching your fuel pressures and checking for charge system leaks. This test would (for the most part) be useless with a delete.

@@AcousticHills Thanks you a lot. I have 2 trucks ProStaR near me, and both have low power - on my channel here there are videos with BOTH of them - i could make an English soundtrack if wanted and post those movies to UA-cam again. These trucks seems to be very pretty to their owners-operators, but so poor power that we almost mad about it...

And another one ua-cam.com/video/v_gzUhTmJ8g/v-deo.html

@@diagnost_gitarist on a stock (factory) Maxxforce 13, for low power I would check to make sure the turbo actuator is not seized, make sure the air control valve is working proper and check the exhaust back pressure valve to be sure it's not seized down.

@@diagnost_gitarist I have seen the exhaust back pressure valve stuck closed even on deleted units that caused it to have low power. Make sure the rod is not visible and is staying up. It's located behind the turbocharger

Thanks

Damn 140 on the dash 😱

@@matthewgarmon3158think that’s kilometers, in miles it’s 85

Hey there! Yes it is, still going strong. Batteries don't hold their charge as long but that's to be expected from something used that heavily. I'll get the batteries rebuilt if it gets really bad. It still pulls nuts like no one's business tho 👍 My buddies that bought the Milwaukee 3/4" had already had the whole units replaced, so that's saying something about durability and longevity. Cheers mate!

Yes they are!

Remove the steps and it'll come off. Takes some playing around.

@@AcousticHillsDid it today & it was a pain like you said, but not complicated

Haha! Yea those were a pain! Glad they went this route too!

Hey there. See if you can hook up to the ecm and see what the codes are. If you cant and it's not cranking. I would check for power and ground to ecm and tcm.
