CODE: P219A BANK 1 AIR/FUEL RATIO IMBALANCE WHAT DOES IT MEANS? (PART.1)

[@danielvitolo2595]

For anyone reading, I had this code on my 2015 accord. I replaced my spark plugs and gas cap. It was the spark plugs in my case. Engine light is gone, it’s been over a week

Thanks. I have this light and my Ford Fusion has 135K miles and the spark plugs have never been replaced. I'm trying that first.

I got this on my 14 accord today

[@lonetraveler5660]

Maf, o2, vacuum leaks, fuel injector, pcv valve etc. all could cause air fuel in balance

So ever figured out what was the problem?

[@andresquinonezramirez9373]

So I ended up finding more information about this code and I end up replacing all 4 spark plugs
