SES light Problem with my 2002 Chevy S-10 Blazer.
Engine size = V6 4.3L
Warning lights = Service Engine Soon
GM Computer codes = P0446 (evaporative emission system vent)
Repair work done prior = No recent work and also passed smog within this month.
Question = I just purchased this vehicle and it passed smog. I need to know what part needs to be
replaced to fix this problem please.
This code P0446 can be caused by a leak in the evaporative emissions system, but is usually caused
by a faulty vent solenoid.
The vent solenoid is located above the spare tire. The solenoid is about $45
Have also had a few bad pressure sensors on top of the fuel tank, but P0446 is usually caused by a
sticking / faulty vent solenoid
|every thing on my 2001 blazer works perfect,light comes off and on abs light, it is
like new or better. help.
