P026D HELP !!!! WONT SMOG

[Ffeggleston]

Tried to smog today and my test are failing because some of my emission monitors are not coming back on. This code when read states fuel quantity error or something of that nature. I went from a SFT Stage 1 tune back to stock and have drove it probably over 500 miles. They have verified that it in fact the stock tune that is loaded. I have even installed new fuel filter just for good measure, cleaned DPF Injector, air filter, and MAP. Any ideas on what I can get to fix this. I do have an appointment at the dealership, but it is not until next week.

This code is common among all (HPCRs) What you will read on the net are complex costly procedures and diagnostics, It easily fixed and cost only time. The procedure needs to be explained, VIA Phone, You are welcome to call Me and if you want to post the fix is fine with Me, I'm tried of My info finding its way back to 1500diesel.XXX.

Greets all,

New to the forum and slammed headlong into the same issue as the user above.

I thought it was a clogged MAP sensor, but pulled it, cleaned it, cleared the codes and... boom... a few miles later, it pops back up (P026D). The code info is, not very helpful. I'm wondering if it's a air leak in my intake? Or...?

Any help or ideas would be greatly appreciated.

 

[Ffeggleston]

Still in the shop since nov6th of 2020.

 

[Temerarius]

Any idea what the issue is?

I'm trying to avoid the dealer at all costs, they have never been (in my experience) even moderately capable and tend to break stuff along the way.

 

[Ffeggleston]

Yep. I’m trying to go through lemon law.

I had that code this summer. It came on, but the truck continued running perfectly fine. I took it to the dealer. They cleared the code out and found nothing wrong. They said it possible the fuel may be borderline or it could have been a glitch and this was fairly common. Months and thousands of miles later, no issue.
I believe the code is for an unexpected quantity of fuel injected.

 

[Ffeggleston]

Yep agreed. Problem is mine will keep that code on until it throws the light. Then with a light on it won’t pass smog.

 

[Temerarius]

Fun!

I'll run it awhile longer and see. The truck has 81k on it and this is the first time this has popped up, but, it popped up right after I changed the air intake and had the Manifold replaced/redone (looked a bit like a chocolate cake in there), so I wasn't sure if they might have been related.

 

[Ffeggleston]

Ya my intake, EGR, dpf have all been changed.

TC Diesel, I have that trouble code P026D and I'd like to clear it off. My truck has 51850+ miles on it. It came up after refueling. I cleared it off and ran good for 3 days. Now the code is back.
I'm new to this forum. I need to know how I can get in touch for solving the issue.

I also had the P026d-00 code. My Diagnostic tool(Autel MaxiCom MK808BT) described the problem as "Fuel quantity higher than expected". I thought to myself "oh crap" I had just done an egr tube clean and map sensor...I should have used new gaskets. My Bad. Bought the parts and put it back together again.
The Pn. is 68211320AA for the metal gasket & 68211212AA. total cost $34.00 and I bought an extra set to have on hand for when I need them again.
So far, I have driven 154 miles without the code coming back on. Hope this helps.

P026D
My experience with this code.
I installed a PEDAL COMMANDER on my truck because it was too slow to come up to speed. I set it a little higher like sport mode 2 or 3. I drove to Colorado over a weekend drive. At some times I would floor the pedal to pick up speed. Coming back home I put in diesel and got on the road, this is when the code came up. I cleaned the egr tube and mapp sensor. They weren't terribly coated like I thought. I cleared the code and around 150 miles later the code came back on. I removed the PEDAL COMMANDER and cleared the code and hasn't come back. Its been like 2 months now with thousands of miles more. I'm convinced that flooring your pedal because the lag these ecodiesels have will eventually throw this P026D code.

Installed Pedal Commander on my truck and set to sport mode. After flooring the pedal over a weekend drive the code came up. I cleaned the egr tube and mapp sensor, wasn't that bad, cleared the code also. 150 miles later it came back. Removed the Pedal Commander and cleared code again. The code hasn't come back since. It's been 2 months and thousands miles now. I'm convinced that in the process of trying to overcome the lag on these trucks by flooring the pedal will eventually throw that code. This is my 2 cents.
