Does anyone have experience with this code? P20EE - Catalyst Efficiency Below Threshold Level.

I'm going to stop that word from being posted if you don't stop using it..

No Problem, The Term is used in everyday use in the commercial World, its Use in connection to Large fleet owners that retard the Power. Their are 15L Engines that are So XXXXXX that 8.3L Cummins out pulls the Bigger power plants.

Deleting or deleted refers to Illegal acts.......Its unwise for any Business owner to connect themselves to act(s) that May cost $1000+ to fight off , No official is going to connect that word to Deleting in any court Action, maybe the Owner(s) has reason(s) Not to mention deleted.

Next time you can ask the OP for the Info, I'm out, until the info needed to help out is available.

I have a 2015 56000 miles and just had that same code. I ended up buying a portable steam cleaner off Amazon and cleaned the DEF injector and the inlet. DEF will crystalize and clog. 2000+ miles later still no code. Their is a YouTube video on it if needed.

Andy , your 2015 has NO urea sensor mix 2 Gallons Distilled water to 1 Gallon DEF. No codes error free for Years.

TC, We spoke on the phone a few months back. I have been adding Distilled water into the DEF tank. Works the same and the exhaust smell is not as strong.

But you still got the code recently after using a dilution and needed to steam clean?

 

[TC Diesel]

Ecopete, That's a Valid Question, AndyRv chime in Please.

 

[Ecopete]

I guess AndyRv did say he's 2000+ miles code free, but he also had that code recently, so I'm a little confused.......

 

[Tremper126]

I wonder if he was saying he had it a month or two ago and put 2k since the code.

 

[AndyIRV]

Yes, Tremper126 you are correct.
I started diluting and it was a matter of days after and I got the code. Steam cleaned and have been code free since.

 

[AndyIRV]

Well, I spoke to soon. I got the P20EE again today. Cleared the code with the scan tool will see how long it lasts. I can't believe its crystaled up again already.

 

[TC Diesel]

Its not........ Something else triggered it this time.

From what I have read, there are a lot of issues that can cause this code to come up. I had it the other day and was scheduled to take the truck to the dealer, went on a 100 mile road trip and the code disappeared. I assume that it was some type of crap on a sensor to the DEF system.

Other issues can be:

Dirty fuel, issues with the DPF, leaks in the exhaust system, NOx sensor issues, DEF injector problems or just a dirty connector...etc.
