Honda fit 2013 base model. P219A code
Wanted to get this out there because we couldn t find it online anymore… Honda is having issues with fuel injectors. We had changed O2 sensor, air filter and checked valves… Ordered injectors to switch out and supplier said that was the 4th set this week for a honda

P219A - Bank 1 Air/Fuel Ratio Imbalance

You will need to see a mechanic with a scanner and check fuel trims and misfire rate and O2 sensor operation when the engine is in closed loop. Engine could be running lean (too much air) or running rich ( too much fuel). If the engine is running lean, causes could be a vacuum leak, a bad MAF sensor, engine misfire, a stuck open PCV valve or clogged or bad injectors or low fuel pressure. If the engine is running rich, likely causes are a bad heater or heater circuit in the O2 sensor, a bad ECT sensor, bad MAF sensor, stuck open thermostat or leaking injectors.
