Hello Piloteers!

I just registered for the forum. Our family have owned a multitude of Hondas over the years (Civics, Accords, Odysseys and an N600(?). My wife loves her Pilot.

I'm currently at the dealer (Bernardi Honda in Natick, MA) with my wife's 2016 EX-L w/Honda Sensing 4dr SUV AWD (3.5L 6cyl 6A) with ~41,500 miles on it. Which has an intermittent "Emissions System Problem" message. I pulled the following codes off of it:

P0430 - Powertrain
Catalyst System Efficiency Below Threshold (Bank 2)

P219B - Powertrain

P0306 - Powertrain
Cylinder 6 Misfire Detected

I'll post back with what they come back with. I set the expectation that this should be covered under the 5 yr/60,000 mi powertrain warranty.

Thanks,

Paul

Thanks for sharing your experience. We may be looking at same thing...

On the way home from work today, my wife said that she saw all sorts of dashboard lights come on and the Pilot has sluggish start followed by surge/bucking. She drove it straight to the dealer and gave her a free rental. They are going to look at it tomorrow.

The dealer replaced injectors and adjusted valves, kept it for a couple days and drove it around to verify the fix. They had to call Honda to come up with the fix who reported they have seen similar cases across the US.

I've got almost exactly the same thing. Error codes P0430 and P219B. I haven't seen P0306 yet. They've been popping on and off for months. I don't know if it is pure coincidence or not but roughly the same time our newer pilot started popping these errors our 10+ year old Accord also started popping emission system warning but that one was for O2 sensor. During my last scheduled service I told them about it and they did the software update on the Pilot. Error codes continue to pop up periodically.

I live in Oregon and I've heard that Oregon can be a dumping ground for bad gas. (not sure why) I've been playing around with different gas. Premium versus regular. Chevron versus Arco. Even tried zero ethanol (WAY more expensive so not a solution but was curious to see what difference it would make). Haven't made any solid correlation. For a while we even suspected our bluetooth connected phones were somehow a factor. Also been trying to be aware of any weather correlation, temperature, humidity, etc... I have found no rhyme or reason to it.

I'm fast approaching the 3 year mark from time of purchase. Based on other solutions of injectors & rails, catalytic converter, etc... I think I better force the issue w/ dealer again.

Now that some time has passed, anyone that posted a solution that worked for you. Is it still fixed or has it come back?

I'll follow up if/when mine is figured out. With how frustrating this has been for us, I'm very sympathetic to others who may be trying to hunt down solutions.

So, was the fix covered under warranty?? You had 41,000 miles correct?

P0430" -powertrain catalyst system efficiency

I have a 2016 Honda Pilot EX that I bought in December of 2015. I currently have 82,000 miles and I have had the emission system error message. The first occurrence was 15,000 miles ago. Fearing further damage I took it to my local Honda dealer as my normal mechanic is over an hour away. They stated I had bad fuel injectors. Being out of warranty I was quoted $1200.00 to replace all the fuel injectors/rails plus labor. I paid the $90 diagnose fee and declined the work. Ironically when I picked up the vehicle the check engine light was off. I immediately took it to my regular mechanic and he said all the codes had been cleared and said to drive it until the code popped back up. The vehicle has been fine until twp weeks when the error code reappeared. I had no impact on drive-ability, idle, gas mileage, etc and continued to drive the vehicle until I could get it back in to my regular mechanic. Ironically after two days the message cleared on the dash. He pulled the P0430 code. During his research he said there is a service bulletin related to this issue and a software update should correct the issue. I will post an update if this indeed solves my issue.

Do you know what TSB this is?

HondaPilotKC -- If your dealer said way back when that you needed new DI injectors, then you'll certainly need them now. The PCM update corrects an issue where the DI injectors get carbon buildup. The PCM update will NOT clean the DI injectors if they indeed have carbon buildup.

I recently had a similar situation. My emission warranty covered the repair for the 6ea DI injectors. Unfortunately, you are now out of emissions warranty.
https://www.piloteers.org/forums/11...ssions-system-problem-check-engine-light.html

IMHO...it now looks like you probably facing the replacement of all 6 DI injectors (they come as a kit). Hope it works for you...

I am having the same prob. I had my light come on n off since 36k warranty. The code comes as catalyst converter prob which is covered upto 80k. Before replacement the dealership just wanted to update the software. I did that. It went off. A month later.. the light is back on. 3 days after and now at the service.. off again. The code is coming out same (was told. Need to see to confirm) but the dealership now thinks it's the fuel injector and may need to replace... BUT i was informed from looking online that it is not under power warranty (80k) I think this is crazy and should be a manufacture recall!!!! Yes.. this is happening to a fairly new 2016 we all want to enjoy! So frustrated. Advice please.

I had the same issue of fuel injector, catalytic converter, spark plug misfire. All issue relates to emission system of my 2016 pilot EXL.

in three years I had already changed 3 converters, twice fuel injectors, and god knows what else on my pilot. At this moment, i don't know whom to blame? the service center or the honda?

I am exhausted with the money i had spent. Just last week I fixed P0430 error with dealer by paying 1400 dollars. One week later I am back with same code and now they want to change injectors.

If I was in your situation and didn't have extended warranty, I would trade it in for a Highlander or something else. Sorry to hear your problems. I don't know how many injectors they replaced at a time (hope they did all in my case), they shouldn't replaced them twice if they did all the first time.

Go get you a Lund's fuel injector cleaner!!!

Two days ago, Jan 21, 2019, I took my pilot into the Honda dealership because the emissions system warning came up on my dashboard. Always, when a light comes up on my dashboard, my first thought is to look through the manual. So for that, it stated that I needed to take it to the dealership right away. So I called and took not in. They will tell that they need to run it through their computer tonsee what's wrong with it. The cost was $115 not including taxes. I can get it back IF I get it fixed right away after they find out what the issue is.

The problem was the fuel injectors being contaminated. They also pointed out that I needed to replace a pipe leading to the issue. The cost for the parts which were the fuel injectors was $838 and labor was $400 and something and does not include taxes so it came out to $1565 or so. Anyways, the question now was whether or not to let them fix it for me.

Before I said YES! There were a few things that I needed to see first. These are some of the things that you need to check out first before you make your decision.

1. See if it is covered under warranty. If it is, that's great. If it's not, then option 2.

2. Ask them for a service bulletin for your vehicle to see if your issue is covered under it. Which O forgot, make sure to go online and check if your vehicle, using your VIN number has a recall for it. Anyways, check recall and service bulletin. If the issue for your vehicle is covered under any one of these two then you are good to go. There is no recall that I know of for the emissions system but I stress it because the recall may have something have a part in the problem you're having. Anyways, I checked the recall for mine and there was none. The service bulletin did not apply to my 2016 pilot. It says it's for 2016 pilot but it's only for specific pilots. Mine was not one of them.

3. If you are trying to save money, ask them about the parts. Take a look at the part numbers for your parts and google it online. Yes, look it up online. Just remember, you have every right to those paperwork because you are paying for them. Anyways, they told me the fuel injectors for my vehicle will cost me $535 and the pipe test $300. Those same parts would only cost me $557 online because they were discounted off of Hondafactory website. I asked them if they price match and they said no. In the end they did discount it for me for only $70. Furthermore, they said that the parts if I order them myself will be backordered. This is not my first rodeo with parts. I work in logistics and maintenance so I know what it means. They had the parts for my vehicle, I just refused to pay full price for it.

4. Since I already know that I can get the parts for cheap online, my next option is to find someone that can put it on for me. It's good to have a mechanic on the side as a friend. Fortunate for me, I work with them every single day so all o need is ask and instead of paying $400 and something for labor, I can negotiate it qith them. Some also have their own shop.

5. So after spending 2 and half hours at the dealership. I opted to pay for the diagnostic fee and left with my car. First, I was not going to pay full price. Second I can do it myself and get someone else to put it on. That was the plan until the next day.

6. When I got to work, I explained to one of the mechanics what happened to my car. He said if it's a fuel injector, I need to clean it using Lund's fuel injector cleaner and so I went to O'Reilly's Auto Store, got me a bottle that was on sale for $3.99. I went home after work stopped at Sam's and proceeded to pour all of it in my gas tank and filled it up with gas. Then I sat in the car for 20 seconds and when I turned my car on, the warning sign went away.

I was able to fix the issue using a $3.99 fuel injector cleanser versus paying Honda $1565.

I had same issue. They replaced fuel injectors and Honda covered 80 percent for goodwill. Weeks later my car lights still go off. Now shows brake problem, etc. today was a key problem. Something everyday. But then it goes away. Now I think it’s just a computer software issue. I’ll be trading in.

Here to add my 2 cents. 2016 Pilot EX-L, 21k miles.
Got the emissions system problem message yesterday and drove it to the dealer today. Pulled code P0430. Dealer said software update. We purchased a Honda care plan when we got the vehicle since it was the first year for the design—there’s a dealership in Cali that sells it cheaper FYI, and we don’t live in California.

Anyway, I had referenced bulletin 18-025 in my call as I had found the issues online. They said per 17-036 they have to update the software first. Then if the code comes back, they will do the injectors. Today’s update was covered with our warranty. I asked the tech if they had seen this a lot and he emphatically said yes. I asked if they could do the injectors now to avoid a trip and he said our plan will only cover it if the code comes up after the update.
I also asked if anyone locally had had luck with just the software update and he said he only knew of one person. So...I’ll plan on another trip.

Mine were replaced in year one (2016, or 2017, bought in September 2015). They didn’t show me how the injectors looked, but I believe probably like yours. Good thing is the issue hasn’t reappeared. Hope it will last a long time.

That’s good it’s def a pricey fix if you can’t do it yourself, they also changed the original part number they must of had a bad batch.

When you bought the injector kit - did it come with all the new O-rings you needed or did you need to buy separate gasket/O-ring kits for the install? I'd love to have a parts list of what you needed to buy if you have it handy - if this comes up, I will do this repair myself and would like to get everything ordered correctly the first time.
THANKS so much for posting by the way - those injectors are terrifying to see!
