On-vehicle inspection

  1. Check fuel cut rpm

Toyota RAV4. Check fuel cut rpm


  1. Increase the engine speed to at least 3,500 rpm.
  2. Use a sound scope to check for injector operating noise.
  3. Check that the operating sounds stop momentarily and then resume when the throttle lever is released.

Hint:

Measure with the a/c off.

Fuel return rpm: 1,400 rpm

  1. Check for leaks

Toyota RAV4. Check for leaks


  1. Visually check that the hoses, connections and gaskets have no cracks, leaks or damage.

Notice:

If the result is not as specified, replace parts as necessary.

  1. Check line and connectors

  1. Visually check for loose connections, sharp bends or damage.
  1. Check fuel tank assembly

  1. Visually check for deformation, cracks or fuel leakage.
  1. Check fuel tank and vent line

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:

If the pressure does not drop, replace the fuel tank assembly.

  1. Reconnect the vent line tube to the canister.
  1. Check air inlet line

  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.

  1. Reconnect the air inlet line hose to the charcoal canister.
