P0352

On codes P0352, 353 etc it mentions coils a, b,c etc- is "a" the same as plug #1? Does this mean the coil is bad or does it mean the wire to the coil is bad?

Steve Says,

Thanks for asking me your question. Coils and plugs are not the same thing. Coil A is simply the term for one of the ignition coils.

This code does not mean that the coil is bad necessarily. It is possible that the coil is causing the problem but there are many other things that could be causing it. It could be a wiring problem, computer problem, low battery voltage, etc. Probably the most common cause of this code is the coil, but there are many other things it could be. You would be taking a chance if you just replaced the coil.
