can each sensor be isolated to detect which is faulty?

Question

check engine light on, clean the airflow and throttle body. light still on. p0106

Answer 1

Hi there,

This code is for the map sensor, cleaning the throttle or the mass air flow sensor isn't going to resolve the issue. Most often the map sensor itself is the problem. When you start the car it sends a signal to the computer of the manifold pressure.
