ON-VEHICLE INSPECTION
1. INSPECT FUEL CUT RPM
(a) Increase the engine speed to at least 3500 rpm.
(b) Use a sound scope to check for injector operating
sounds.
(c) Check that when the throttle lever is released,
injector operating sounds stop momentarily (at 2500
rpm) and then resume (at 1400 rpm).
Standard
2. CHECK AIR TIGHTNESS IN FUEL TANK AND FILLER
PIPE
(a) Disconnect the vent line hose from the fuel tank.
(b) Connect the pressure gauge to the fuel tank.
(c) Apply pressure to the fuel tank to create an internal
pressure of 4 kPa (41 gf/cm
2, 0.58 psi).
(d) Check that the internal pressure of the fuel tank is
maintained for 1 minute.
(e) Check the connected portions of each hose and
pipe.
(f) Check the installed parts on the fuel tank.
If any malfunctions, damage or other problems are
found, replace the fuel tank and filler pipe.
(g) Reconnect the vent line hose to the fuel tank.
3. INSPECT FUEL CUT OFF VALVE AND FUEL CHECK
VA LV E
(a) Disconnect the vent line hose from the fuel tank.
(b) Connect the pressure gauge to the fuel tank.
(c) Fill the fuel tank with fuel.
(d) Apply pressure of 4 kPa (41 gf/cm
2, 0.58 psi) to the
vent port of the fuel tank.
HINT:
Check the amount of fuel in the fuel tank. When the
fuel tank is full, the float valve of the fill check valve
is closed and no air can pass through.
(e) Remove the fuel tank cap, and check that the
pressure drops.
If the pressure does not drop, replace the fuel tank
assembly.
(f) Reconnect the vent line hose to the fuel tank.
Item Specified Condition
Fuel cut off rpm 2500 rpm
Fuel return rpm 1400 rpm

4. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal
canister.
(b) Check that air can flow freely into the air inlet line.
If air cannot flow freely into the air inlet line, repair or
replace it.
(c) Reconnect the air inlet line hose to the charcoal
canister.
5. VISUALLY INSPECT HOSES, CONNECTORS AND
GASKETS
(a) Check for cracks, leaks or damage.
HINT:
Removal or problems with the engine oil dipstick, oil
filler cap, PCV hose and other components may
cause the engine to run improperly. Disconnection,
looseness or cracks in the parts of the air induction
system between the throttle body and cylinder head
will allow air suction and cause the engine to run
improperly.
If necessary, replace any damaged parts.
