2005 Kia sedona P0320 Code. Engine works ok but the Tachometer doesn't work. What need to change?

Question

The engine works ok but the Tachometer doesn\\'t work and the service engine is always on. What need to change?

Answer 1

This code is for the ignition fail sensor. The tach not working is a tell tale sign it's shot. Eventually the engie isn't going to run either.

My tach stopped working five months ago and runs fine.
