After I installed my VI I got 2 CEL codes can anyone tell me how to fix them?
The Codes are:
0903- EVAP canister vent control valve circuit fault
0705- EVAP system leak

Thanks alot

The evaporative canister collects fumes from your gas tank and then "purges" them into the intake when you start the engine. Your codes could just be a loose gas cap as that causes a leak to be detected.

 

loose gas cap, or evap canister purge valve stuck.

just behind rear driver's side wheel, you'll see a black plastic box. That's evap canister. take it out and shake it.
if there's some water-ish substance, turn it upside down and let the water out.

If the valve is stuck, you have to clean it and put it back.

 

how do u clean the valve if it is stuck?

 

mind you, I have one of the first 4th gens (made in 94!)

mine was like those of the 3rd genners... right beneath the brake master cylinder.

I cut the glue that was holding the valve cover, then opened the whole thing with a screw (-) driver.

But you can just clean the valve by putting air through the hose connected to it, like blowing with your mouth (hmm, the good old way) or compressed air.

 

ill give it a shot tommerow and see how it goes, thanks alot!
