Check engine light came on yesterday reading "p1196 catalytic converter monitor slow oxygen sensor (Bank 2 Sensor 1)."

After a quick Google search there are three possible causes for this code. 1- A bad mass air flow sensor. 2- A leak in the intake(manifold I assume). And 3- A leaky injector.

I'm curious to see if anyone on here knows how to help me narrow down the cause of the code. Any and all help is much appreciated! Thanks in advance.

 

What engine do you have?

 

4.7l v8

 

spray brake cleaner or starting fluid around your 1- A bad mass air flow sensor. 2- A leak in the intake(manifold I assume). And 3- A leaky injector. See if your idle goes up.. if so your getting a vacuum in those general areas.

 

I've also just figured out that my engine doesn't actually have a MAF sensor. I will try the starting fluid idea soon.
