1997 Toyota Corolla Q&A
1997 Toyota Corolla Question: When fueling my 97 Corolla cap is TIGHT,then extreme vapor vents out. Normal ?
Every time we fuel our 97 Corolla the cap is very difficult to remove and then as the seal breaks, it vents vapor for a long time (approx. 13 to 16 seconds). We do not quickly reove the cap due to the pressure, we are worried it may cause the cap to pop away from the vehicle. I understand that the fuel cap is supposed to have a good seal and vapor should vent through a line going from the tank to the purge canister, but is it normal for this vehicle to vent a large anount of vapor each time. When we refuel, we are not on empty. We usually refill at 1/2 to as low as 1/4 tank. My thinking is that there may be a problem with the evap canister purge solenoid. Does this vehicle have such a device and could it be the problem? We do not have any fault codes. This vehicle has done this since we bought it used two years ago. It just recently passed smog inspection in California even though it has this problem. - tfaulk13
vent solenoid is closed and should be open. get a shop to check it, verify and give you a bid. Roy - mastertech6371
