Thanks for the tutorial. My truck threw the P202E code and I replaced the DEF injector. Ran a full diagnostic using a Snap On code reader and got a no reluctant pressure message. Going to change the pump now. Hopefully that will fix the issues.
Overall good and informative video. I have to point out that DEF has nothing to do with regen. In fact the SCR is located after the DPF. DEF is injected into the SCR.
Yes it does. If you do not have a working def pump/injector it will not do a regen. Talk to a mechanic. My happened to be a recently retired dodge mechanic. The ONLY time it really uses def is in a regen cycle. He couldn’t do a stationary on mine because the “reluctant pressure level low” warning. Figured it meant that the pump was burnt out. Sure enough…
Hey man, is the sensor for the DEF level built into the pump or is there a separate sensor that I haven’t read about? My truck threw the P203B code yesterday saying “reductant level sensor A circuit range/performance” and I just want to confirm before I buy this expensive pump. Thanks!
From what I’ve researched everything is housed in that pump assembly, heater, pressure sensor and level sensor. If any one of those things fail and throws a code for it you have to replace the pump assembly. There is very little troubleshooting diagrams for these things and it looks like FCA’s instructions are to replace the pump. Sometimes flashing the ECM to the latest software will fix the issue but it only makes it tolerable. Just my 2 cents. 🤷🏻♂️
Michael Cox, did you change out the DEF pump? My truck just threw up a P203B code today and I wanna make sure that I don’t buy an expensive pump that I don’t need. What fixed your truck?
@@aidos6585 I never changed the pump. I was too busy so I left it for about a month and then one day I got in and the gauge/ pump are working perfectly and has been fine ever since so I just put the pump I bought on a shelf for a spare
In "most" cases no. In this case it was not needed and the codes cleared immediately after install of the new pump. But also in this case another code ended up being generated because the computer couldn't accurately communicate with the new pump and the dealer had to update the truck.
I just replaced mine !! Mine synced just fine !! Dealer told me if it didn’t reset to disconnect the batteries for an hour then hook back up !! It took 3 start up cycles to prime the pump !! Part was 1600.00 WTF dealer wanted 3000.00 to fix !! Took me about an hour to change!! Had 82k on my truck the emissions warranty ran out at 80k !! Can’t wait for 100k to make this nonsense stuff go away!! I used a screw driver and hammer to get safety ring off !! The tool is probably way easier!! My knuckles were bloody!! I cussed it a lot !! I wasn’t going to drop the tank !!
@@mrbear1311 the def fuel hand would not move !! Tried unplugging had the code cleared! It would come right back on . I don’t remember the code . But it was a bad pump !! They say the sensor gets dirty on it and that is the actual problem!! No way to clean the sensor either!! It’s a bunch of BS !!!!!
Mine threw low reductent psi I’ve re gen 2x and swap nox and checked intake then made pipe white white smoke on re gen 2 now it’s hi nox egr shut down so I’m thinking it’s pump mines 15 I also swapped out fluid just in case and cleaned injector if just pump I’d rather fix it then get into any delete being it’s a lot more work and exspense and risk of legal issues I don’t drive this truck enough so I have seen tank didn’t look for the round plate but will probably have money next week so can put her on my lift bidenomics suck

Bro, your videos are the best for instruction. Keep making more. Thanks for making them.
I appreciate it!

That was a very well explained video thank you so much!
Thanks for sharing. Very helpful if I ever need to do this.
thanks for doing this video,keep up the good work.

Def has everything to do with regen lol
Thank you very informative
Great video. My 3500 DEF guage is showing empty but i know the tank is full.
Thanks for the video. I just subscribed.
I appreciate it!
What was the check engine code that your truck was showing?
What pump did you go with? My last one failed in 4 months
I went with an OEM pump from the dealer.
Ouch, how much was that?

I’m getting this p203f on my ram 3500
We’re you getting a p20B9 code?
did it throw a P203F code?
Do you need a special computer to get the DEF light out?
In "most" cases no. In this case it was not needed and the codes cleared immediately after install of the new pump. But also in this case another code ended up being generated because the computer couldn't accurately communicate with the new pump and the dealer had to update the truck.

The dealer also told me don’t let the tank get much below half because the pumps are going bad if the def gets low !! 🤷🏻

What is the tool called to remove the ring?
Fuel pump lock ring removal tool.

Most def pumps get lost in boating accidents.
Do yourself a favor delete your truck! Saves you a lot of money ! I have a 2020 been through 2 def injectors no more!
This is a customers truck, I have tried to talk him into deleting it.
Delete what if you live in California
Won't it be checked?😂
Just wondering
