When the CEL first appeared with the P-0446 I cleared it thinking maybe it was just a fluke. The code reappeared in less than 5 miles.
I know the code points to the vent solenoid, but I also understand that there are other issues that can set this code also. Rather than throwing parts at it, I would like to do testing.
Could you provide me with the testing procedures for this code? The vehicle is a station wagon, if that matters, and engine VIN U.
Thank you in advance for your reply!
