  1. Start and idle engine. Open fuel filler cap. Using scan tool, read off fuel tank pressure value. If fuel tank pressure value is greater than 1000 kPa, go to next step. If fuel tank pressure value is not greater than 1000 kPa, remove fuel tank and replace fuel tank pressure sensor. Fuel tank pressure sensor is located on top of fuel tank in front of fuel pump.
  2. Disconnect hose between CP valve and EVAP canister from CP valve. Start and idle engine. Using scan tool, check whether EVAP valve is activated. If there is no vacuum in EVAP valve when valve is not activated, go to next step. If there is vacuum when valve is not activated, replace CP valve.
  3. Turn ignition off. Remove left front wheelwell. Ensure hose between EVAP canister and EVAP canister shut-off valve are not pinched or kinked. If hose appears okay, carefully disconnect it from EVAP canister and EVAP shut-off valve and check hose for blockage. Replace hose as necessary. If hose is okay, go to next step.
  4. Ensure ignition is off. Remove EVAP canister and let it hang by its hoses. Carefully disconnect hose to EVAP canister shut-off valve. Disconnect end of hose from EVAP canister. If EVAP canister shut-off valve connector in EVAP canister is blocked, replace EVAP canister. If EVAP canister shut-off valve connector in EVAP canister is not blocked, install new EVAP canister shut-off valve.
