Question

There is two valves in evaporate system which one is the p0446 code for and how can I test them?

Answer 1

Hi there,

This code is for the vent control valve. A simple test on this valve is to remove it, then put power and ground to the valve. You should hear the valve click each time you touch it with the ground wire. If you don't, then the valve is no good. If you do, then check the wiring harness to the valve as it may be damaged.
