Toyota RAV4. Check fuel tank and vent line


  1. Disconnect the vent line tube from the canister.
  2. Connect a pressure gauge to the vent line tube.
  3. Apply 4 kpa (41 kgf/cm2, 30 mmhg) of pressure to the vent line of the fuel tank.

Hint:

Perform this inspection with the fuel tank less than 90% full. When the fuel tank is full, the fuel cutoff valve closes and pressure is released through the 1.5 Mm orifice. As a result, when the fuel tank cap is removed, the pressure does not decrease smoothly.

  1. Check that the fuel tank pressure is maintained for some time, and does not decrease immediately.

Hint:

If the pressure decreases immediately, one of the following may be the cause:

  1. When the fuel tank cap is removed, check that pressure is released smoothly.

Hint:

  1. Disconnect the air inlet line hose from the charcoal canister.
  2. Check that air flows freely into the air inlet line.

Hint:

If air does not flow freely into the air inlet line, repair or replace it.
