You can attempt to clear the code and see if it comes back. If so, then there are (obviously) other complications. Possibly bad fuel? Since it says "quantity", not quality, it could be a sensor for the EGR, TPS, or the injection pump itself.
I think first try to clear it.

 

I cleared it, came back with about 15 minutes of driving.

 

It's a huge investment, just take it to the dealer and have them fix it correctly at zero cost to you.

 

I would replace the fuel filter, it's cheap and the process of elimination that you can do yourself very easily and not get a bill over 100 dollars from a dealership and when you start your truck stand next to the fuel tank and listen for a loud whining noise, when a lift pump goes bad folks usually hear it whining first .
BTW I read your other post about leaves in the air cleaner intake causing codes , Thanks for sharing

 

Thank you, I'll try a filter and listen for the pump.

 

My dealer just changed my injectors due to that code

 

Thank you hope its not that drastic. But only a little over a year with less than 20k on it so should be covered under warranty if that's the case.

 

Thank you guys, I'll try a filter first. than if it pops the code again it will be off to the dealer for warranty!

 

Hey guys here is a follow up so far. After a 2 week stent of my truck at the dealership, first attempt for a fix was a bust. They replaced the injector pump and a couple fuel lines. Got it back and within 100 miles the code came back, its at the dealership again, see what happens this time.

 

You got further than I did Chuck. I had a P026C code a couple of days before Christmas. I reset it with my Edge CTS but it came back on last Wed (18 Jan). I got it into the dealer on Friday, 20 Jan. They ran diagnostics and told me my air filter was dirty, that they had to replace it as the first step in their trouble-shooting procedure (the air filter was 6 months old with about 14k miles on it). So, between the charge for diagnostics, the air filter, and the rental car, I spent about $210. They emphasized I may well get this code again and if I do, they'll try something else. Hopefully, they figure out it's something covered under my extended warranty so I'm not out of pocket every time they look at the truck.

injectors...

 

I have the same problem! Mine started about a month ago..truck has always ran fine..i did an oil change and fuel filter change, also added in some diesel clean. Mine seems to come and go with the cold weather. Im in oklahoma and it can be 65 one day then be in the 30's the next... my CEL came back on last thursday and is still on today. Im taking it in saturday to stealership to see what they allow, i will let u guys know

I have a 2014. I just got a check engine light this afternoon. Plugging my code scanner I get:

P026C

and a

P1D30

from a historic fault log. What ever that means.

I tried to reset the check engine light and clear the codes. No luck.

A few days ago, I changed my fuel filter and replaced it with the OEM filter from Mopar. No leaks.

57K miles.

Any ideas?

 

Apparently, there is some type of delay before the check engine light goes off after clearing the codes with my reader and torque pro. This morning the check engine light was off and up until now at least, it remains off.

I will ping this thread if it comes back on for the same reason.

 

P1D30 code was thrown again this evening. Have not seen that code again since the last posting at the end of March. I had torque pro clear it. I suspect the CEL will be gone sometime tomorrow.

 

P130D is "oil Viscosity too low". Its usually thrown if you forget to reset your oil life monitor... do you do your own oil changes? Check the Oil life monitor. Once it's set, Torque won't reset it. you need the dealer to clear it.

As far as the P026C, your dealer is being a moron (as usual). That code is not a fuel pressure code. Its an injection quantity. You have a clogged/defective injector. Given the low mileage, i would suspect a defective injector.

 

I just turned 60 k miles. If i need a new injector(s) are they covered under the standard 100 k miles powertrain warranty?

 

I do not have a FCA extended warranty. fuel filter only has about 3 k miles on it.

I also wanted to report that my MPG took about 3 mpg hit after the check engine light came on. Perhaps this is due to a bad injector. I don't know, but it is something I noticed this morning and throughout the day.

My check engine light is still on.

I suppose I will find time to take it in to the dealer sometime this week.

 

Strange thread as the OP never got back to finalize the results after his return of the code. Taken on new life.

Will sheepdog come back? Stay tuned.

 

Just a note that I had a friend clear the code yesterday evening. He has a device (code reader) from Snap On Tools. I want to see if it comes back without loosing a day at my servicing dealer.

The interesting thing to me, is immediately, I got back about 1 1/2 mpg from the 3 mpg loss.

 

Well seems like my ecodiesel seems to be a lemon, or my local dealership does not know what they are doing! It's been to the shop twice for the P026C code, first attempt they replaced the injector pump and some fuel lines. Lasted 80 miles then popped the code again. Second attempt they spent 2.5 weeks fooling with it to finally said it was the fuel filter. I had just put a new OEM fuel filter on it 500 miles before the first code popped. Went back in for a fuel leak because they failed to tighten a line properly and it was sealing diesel. Lasted about 1.5 months, no issues.Two Thursdays ago was making a small 130 mile trip to a zoo and my oil cooler blew, mind that I only have 33k mikes on this truck! Got it towed, 1 week later got my truck back. Drove it 35 miles and got a check throttle control warning and went into limp mode! WTF! Reset to see if it would come back. Cleared and did not come back. Drove truck up to PA for Memorial Day weekend , and this morning it popped the P026C code again. I'm about to drive it over the Fing cliff!

 

How did they fix your oil cooler issue? They should have replaced your engine if oil was inside your coolant system. Others have had a new engine installed and that would take longer then a week repair in my opinion...

Sorry to read your woes Chuck. Hopefully we can find someone who knows how to really fix it. Did you drop some MPG on the display as well?

As of yesterday morning, my trucks CEL is back on. The same P026C.

 

A update.

Over the last month I have been too busy to get into the servicing dealer about the CEL and the code. It has been on for a little over a month now. Today, I was in a hurry and got a stretch of highway and really drove my truck much more aggressively than I normally do. By that I mean I pushed the pedal to the metal several times and kept it there for a brief period. At some point in that drive my CEL went away.

Just saying.

In any case, I hope to get it in the dealer at some point in July to have them look at the injectors.

 

That was the code I had and they sent the injectors out for testing and they failed. They replaced all 6 injectors under warranty.

 

BTW my truck now averages 22mpg where it was 17

 

Another Update. So my CEL keeps coming on for the same P026C code. But, I can clear it for a few days just by doing a hard acceleration for a few seconds once my truck is up to temp. It goes off on its own, where it stays in that state for a few days and then comes back on.

Still trying to get to my servicing dealer some time over the next few weeks. I need my truck for work and dread not having it for a few days. If I remember correctly, I have 68,000 miles on it.

 

Well I took my Truck in late last week to have the P206C code diagnosed. They ended replacing the EGR cooler under the 100k warranty. Found some wet soot on one side of the intake manifold and Star Center advised them to replace the EGR Cooler.

I picked up my truck this afternoon and within 10 miles it threw the P206C code again. Called servicing dealer and informed them and they said they would put a plan together and get back to me.

I will post back once they have had a chance to look at it and inform me on the next steps.

I am at 68K on the odometer.

 

My truck has been at the dealership for this code almost two weeks which is longer than I have had it since I bought it. I replaced my fuel filter when it started acting sluggish on my first long trip. I brought it to the dealership the Monday after that weekend and they have had it since. So far they replaced the turbo duct, O2 sensor, and turbo hoses. Each time they have driven the truck over 50 miles to see if the CEL stays off but keeps coming back on. Today the service manager calls me to tell me they don't know what to do next and are awaiting Chrysler's direction. It may involve getting the Chrysler field tech to troubleshoot. Service manager said they haven't seen this code very much. Asked him if they checked the fuel system and EGR he said code isn't related to a emissions issue but I wonder about the fuel system. Bought my truck CPO with 41k miles. Definitely second guessing my choice as my 12 Hemi was a beast tuned and never had an issue...

Have they dropped the fuel tank and inspected it for debris? Is the fuel pressure normal pre or post injection pump? Unfortunately that code is very generic but the fact it takes up to 50 miles to set is something to consider. It may even be a defective thermostat.

 

Certainly think it is related to the fuel system but I am not sure. Possible Injectors and or fuel pump.

Does anyone know how to obtain a copy of this Star case?

Star - S1518000024

Apparently there is some info in there related to this code.

RamRZR - What year is your truck?

 

2015

Not sure if this is helpful/applicable, but I found the following on the internet (so it must be true.... LOL);

The engine computer (PCM) monitors the Reductant Catalyst System's use of DEF and its ability to convert NOx to Nitrogen, Carbon Dioxide, and Water. The PCM uses a Reductant Quality Sensor to monitor the performance of the Reductant system. If the sensor sends back an implausible signal, code P206C is set.

 

RamRzr: You are not running biodiesel by chance. My dealer said they have seen issues with running higher levels.

 

No only had 2 fill ups of reg diesel and 1 of those was done by the dealer when I purchased the truck
