P219B
Bank 2 Air/Fuel Ratio Imbalance
DTC P219B, sometimes indicated as P219B00 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing bank 2 air/fuel ratio imbalance.
The P219B code means that the air/fuel ratio imbalance is detected in bank 2. This code is usually caused by a fault in the air/fuel ratio sensor or the oxygen sensor in bank 2.
There are several things that you can do to try to fix this code:
1. Check the air/fuel ratio sensor and the oxygen sensor for faults.
2. Check the wiring and connectors for faults.
3. Check the fuel injectors for faults.
4. Check the engine sensors for faults.
5. Check the engine control unit for faults.

2017 HONDA PILOT with 55000.0 miles
I take my 3 year old, 60k mile Honda Pilot in for emissions system problem light. I am presented with the following fault codes: 19-072 mil comes on with dtc P0430 or dtc P0430 with p030x, P219A, P219B (with software update) - include all parts from bulletin i need a full fuel injector replacement at the cost of $2,000. This is clearly an issue with the 2016-2018 Pilot, but Honda has issued no recalls. Fuel injectors failing at 20-70k miles?!

2016 HONDA PILOT with 58000.0 miles
Warning light: emission systems problem i purchased the car at around 56,000 miles from a non-Honda dealership. This light first appeared around 58,000 miles when i turned the car on in my driveway to go to work. I called my local mechanic (i.E not a Honda dealership) to ask to bring it in for diagnosis, but by the time i brought it in about 3 days later, the light had gone off. My mechanic read the diagnostic code P0430. Per tsb #17-036, this code meant i needed to update pcm software, and he told me to talk it to a Honda dealership. From this point until i took it to the Honda dealership, the warning continued to go on and off for days at a time. I went to the dealership on 6/8/19 and the car was at 59,184 miles. I told the service advisor what i had done so far. After diagnosis, he informed me that the pcm software had already been updated by the previous owner, and that they found code P0430 b2 cat fault, indicating the need for a new catalytic converter. This fell under the emissions warranty and it was replaced a not cost to me. Shortly thereafter, the warning light pattern occurred again, coming on and off sporadically. I waited a while before taking it back to the dealership, but took it there on 9/21/19 with 64,788 miles. This time, the diagnosis was codes P0430 and P219B, which is explained is tsb #18-025, and i was informed i would need new fuel injectors, which would not be covered under any remaining warranty.

2016 HONDA PILOT with 62500.0 miles
We bought a 2016 Honda Pilot ex awd from a dealer a month ago with 62k miles on it. Three days ago an emission system problem and check engine light came on. We took it to the Honda dealer immediately and the codes were P0430 and P219B. They diagnosed that one of the cylinders was running rich and misfiring. All 6 fuel injectors and a flex pipe needed to be changed. The estimated cost was $1700. I called Honda america thinking this is happening too early to a 3 year old car with relatively few miles on it. My other 2011 Honda is at 145k and never needed fuel injector replacement. I researched it online and found that this is a common problem among 2016 Pilots and there is a service bulletin for it 18-025. Honda america said there is no recall on it and that the 3 year 36k warranty is over. I am aware of those, but a 3 year old Honda should not need this replacement. They are researching if they should assist with the cost of the repair, and will get back to me in a few days. However, i would urge others with similar problems make a complaint here and pressure for a recall. If this problem continues and the car goes to limb mode in the middle of driving, it could lead to an accident. It would also not be safe being stuck next to a highway with a car not working. I am glad in my case it was noticed early on when the light came on. This is also an expensive repair early on in a car and should be fully covered by Honda.
