hi my check engine light was on and our local garage said it Pulled code p219a bank 1 sensor 1 air flow ratio sensor, they replaced it but warned if the light comes back on it might need the valves adjusted. It did come back on2 days later and we had the adjustment done. After all that the check engine is coming on and off and staying mostly in. Mechanic said this is crazy and we only have 74000 miles, it is pulling what he called a minor code now but was going to check with Honda, that was weeks ago! Has anyone run into this?
