I have a 2012 Kia Rio lx I have changed the crankshaft positioning sensor and the wiring pigtail and now it is hard to start and my tach quit working. What should I do to fix it?

What is your question?

The check engine light is still on and the code says the crankshaft positioning sensor voltage is faulty.

What makes this problem better or worse?

it is about the same all the time.

How long has your 2012 Kia Rio had this problem?

A few weeks now
