The evaporative emission (EVAP) system may illuminate the vehicle's Check Engine Light due to intermittent failure of the charcoal canister purge control solenoid valve or canister failure. Upon failure of the charcoal canister, debris may circulate around the EVAP system causing other emission control problems.

My situation seems to be almost textbook "average" situation. 1. VSC lights + Check engine lights appear, triggered by idle or slow RPM situation. 2. Tried "fixing" with tightening gas cap, taking neg. terminal off battery for 15 minutes + pulling fuse to reset system. 3. Seemed to work. Went for a couple weeks without lights. 4. Lights returned. 5. Took to repair (dealer) for diagnostics, quoted "bad charcoal canister and/or sensor". 6. Quote: $110 for diagnostics + $500 for part (canister) + $200 labor = $800. (this is at Elmhurst Toyota near Chicago).

Check engine light on and trac control disabled. Gas mileage terrible when code P0440 is set. First tried gas cap from dealer. Nope. Code returns. Smoke test reveals bad charcoal vapor canister. $485 at dealer plus $150 labor to install. I am going to pull canister and look for leak myself before spending that kind of cash.

Check engine light came on which also triggers lights for Traction Ctrl. Diagnostic shows code 0440. Replaced charcoal canister

Check engine light on as well as vsc,trac lights. Dealer pressure tested the evap system and told me it was my charcoal canister. 435.00 for canister and 150.00 labor. I did not fix and have been driving it for about 6 months now. I might pull it out and check and replace rubber o rings, and reset the check engine lights to see if that fixes problem first.

I have read a lot about this problem. Have had the two valves under the hood replaced and replaced the fuel tank. I am smelling gas fumes from under the car and the fuel tank is not holding pressure. I am guessing it is the canister...

saw the check engine light was on as well as one other light (can't remember the name) but at the SMOG check spot, the results showed "P0440 EVAP CTRL System Malfunction"

Same issue with Check Engine + VSC Lights stay on. I discounted the battery and the light went OFF, but they came back on after I put 3K mile on the truck.

check engine lights come on, trac control system disabled, Mechanic reset engine lights and it ran great. Now less than a week later it is on again. The mechanic said they need to replace the valves and canister.
