How I 'fixed' poor DEF and engine derate on Volvo Truck

Do, what I did, on your own risk!
I am not, neither will be, ever, responsible for any damage or injury resulting from actions yo do after watching my video!

This being said, I want to thank you all for watching!

I looked into this. DEF fluid has ammonia in it. It’s one of the ingredients. I tried this when my truck showing POOR DEF QUALITY. When it was showing this it wouldn’t even do a parked regen. I stopped at Walmart, got a bottle of ammonia and. Poured it in and an hour later the warning lights went out. It’s been working great since then. Now I pour in some ammonia every so often to keep the system clean and it’s been great. The good thing is that my boss told me to do it. That’s why I investigated 1st. I didn’t want to be stuck on the side of the road. I don’t know how you found out about it but thanks for sharing. It worked great.

I did it today.... it worked.... i added 1 quart of clear amonia.... i had approx 1/4 tank of def fuel already in the tank.... i added a box (2gallons) of fresh def fuel because i wanted to delute the amonia a little bit.... after 1.5 hrs of driving the poor def warnings went off... i was 45mins away from engine derate.... thanks dude

You got subscriber after this video. This was the best and only video explained very well with solutions for the problem😊

I have a hint, only buy def in container. Do not buy it from truck stop pump. Also if you have to buy it from truck stop pump, invest in a refractometer and check the def before pumping it into your tank. Simple and cheap insurance that you’ll never put bad def into your trucks tank.

Swear to God i have same codes I injected 1 gallon and did force regan with OTR TOOL drove local overnight and turn speed sensor back my truck is clear running like beast before it has codes for filter clogged leake full dpf line clogged or Leake DOOSER VALVE not enough pressure but trust me my volvo is excellent now thanks again

Or you can just purchase OTR Performance Regen Tool which will let you to delete all Active/Inactive Faults. It will also let you do Parked Regeneration and reset soot level. The best $450 investment I ever purchased.

slick trick, basically boosting the ammonia content, wouldn't have thought of that

Thanks a bunch, this little hack got my truck going down the road again.

FYI the filter cleans out the soot, DEF only plays a part in clearing the soot off the filter; with a high enough exhaust temp (sufficient load or, while regenerating, high rpm and Jake engaged) the DEF combusts with the soot to burn it off as CO2, water vapor, and N2.

The reason for its continuous injection is actually to control nitrous oxide output, which is why we have to use the weird filters that we do with the platinum in it, its the same as a catalytic converter on a car.

Here's the irony: If it wasn't for the filter causing NOX increasing in the first place we wouldn't need DEF. We need better filtration systems, or better engines like the Cummins that have low soot/ash output to begin with and no DEF system at all.

I drive a Paccar powered Kenworth T680, but I think the same basic tips you gave apply to all this def mess thanks bro!

[MrSwordfisher]

OTR reset is a diagnostic tool, also if every is working properly it can erase codes and initiate force regen, only if components will allow the reset tool to work…

You can program your truck so when you disconnect speed sensor it will not lose any power. If you have a TECH TOOL, there is a line in programing parameters calls tempering speed sensor. Usually your truck programed to cut your power by 50%, in this option you have to change to 100%. after this you will not have any power loss when disconnecting speed sensor.

Only you have to do is make Regen continiusly . untill the light on dashboard disappear

[rusmirdevlic]

you pull out the speed sensor and drive for about 100-200 and it's going tp be fixed for couple weeks or so

[garysargsyan]

There is no specific onboard sensor that would probe and check your DEF quality. Most of the time when you get poor DEF quality light and then engine derating, it means there is a much-complicated issue than DEF quality alone. One of the major issues is the SCR is bad/ partially clogged up or not enough heat is being generated inside of it to keep that chemical reaction going on. 2.- check the dosing valve. My truck gets POOR DEF quality light only in wintertime, never in hot summer, meaning, hot summer temps help to break down that soot inside your SCR. My advice is, don't put ammonia inside your def tank, cuz it's way worse corrosive than DEF. Good luck.

thank you man for this video ...
Same thing happened with my Volvo 2015 ... I was trying to do engine regan but the system keeps refuse for regan and later I start driving with the check engine light on and later disappear and later back again !!!

[tylerseabook]

The crankshaft going into the gears? You realize how dumb that sounds

[damianm]

I see that you have ABS light on. I have the same ABS light on and I'm wonder if you did find the problem with it? It seems to be common problem on Volvo's.

[billestep]

Unplug the speed sensor on the transmission of a Volvo will keep it from drrating

[oguzeki]

You put it into def tank rightyou mixed With the def, püre ammonia . Thanks a lot
