I have a 2014 IS350 F with 55k miles and am getting a P219C code and can’t find much information other than it could be one of 12 things. Does anyone have experience with this code and good recommendations for where to start?

 

Is the Intake and Exhaust on the vehicle stock? Do you notice any exhaust leaks?
Have you changed spark plugs recently? If not, is it maybe time to change plugs?

For that code the issue is with cylinder #1...the first cylinder on the passenger side of the engine.
I would check for an exhaust leak first from around the cylinder head...which is very unlikely.
Second I would check the spark plug.

 

I believe that it is all stock. I think the plugs are due to be changed soon. At 60k I believe.

 

I would suggest starting with the easy solutions first and change the plugs.
Whether it fixes the issue or not, it's still a good idea seeing as the car is approaching it's 8th year on the road.

 

Thanks, I bought this car within the last year. I got plugs and if the weather is decent I will change them this weekend.
