evap code PO0443

[dynabill]

i wish i know which system you have, 1 or 2 evap.? yes me too, lol. I know my way around these pretty good, but this is new territory.I checked b chapter and I dont have three hoses coming off of the evap canister. this is the only difference i could see in them. although I do have a nipple on the bottom of the evap canister that has no hose for it to connect. I am pretty sure, my 95 had a hose that it connected to.

1 solenoid or 3.?

there are lots of tests, on EVAP2 , way more. lots of things can fail.
1: the tank, all hose, all parts. related, leaks, or bad vacuum lines, or bad VSVs (up to 3) bad reg, bad gas cap. or ECU controls dead or stuck.

let me know how you do.

to correct the FSM.
1: Do not blow or suck with mouth or lips, any fuel parts (benzene is a known carcinogen) Keep in mind the EVAP canister is Benzene trap, it saves up this nasty solvent, one of the worst)
2: but do use a mityvac or HF clone hand vacuum tool , it can do wonders. I have one of these and will check all hoses



IF Evap 1, ?
i try first to see if the ECU is finding NO AIR flow, or too much. knowing what it finds, is the best clue to the solution. in every case. (but can be hard to discover this) will the scan tool tell me this? Is this where I will have the option for a freeze frame from the scan tool. these are also new territory for me. hahaha

thanks Jerry I will let you know what I find. Bill
