On-Vehicle Inspection

2GR-FSE EMISSION CONTROL: EMISSION CONTROL SYSTEM: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. VISUALLY CHECK HOSES, CONNECTORS, AND GASKETS






(a) Check that there are no cracks, leaks or damage.
- Detachment or other problems with the engine oil dipstick, 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 an engine failure or engine malfunctions.
If the result is not as specified, replace parts as necessary.
2. CHECK FUEL CUT RPM
(a) Start and warm up the engine.
(b) Open the throttle valve and keep the engine speed at 3,000 rpm.
(c) Use a sound scope to check for injector operating noise.
(d) Check that when the accelerator pedal is released, injector operation noise stops momentarily and then resumes.
If the result is not specified, check the injectors, wiring and ECM.
3. CHECK LINE AND CONNECTORS
(a) Visually check for loose connections, sharp bends or damage.
4. CHECK FUEL TANK ASSEMBLY
(a) Visually check for deformation, cracks or fuel leakage.
5. INSPECT AIRTIGHTNESS IN FUEL TANK AND FILLER PIPE






(a) Press the lid switch to release the pressure in the fuel tank.
(b) Check that the lid is opened.






(c) Disconnect the vent line hose from the fuel vapor containment valve.
(1) Pinch the retainer and then raise it.
NOTICE:
- Do not use any tools in this procedure.
- Check for any dirt and foreign matter contamination in the valve and around the connector. Clean if necessary. Foreign matter may damage the O-rings or cause leaks in the seal between the valve and connector.
HINT: Do not remove the retainer.





(d) Connect the pressure gauge to the vent line hose.
(e) Apply pressure to the fuel tank to create an internal pressure of 4 kPa (41 gf/cm2, 0.58 psi).
(f) Check that the internal pressure of the fuel tank is maintained for 1 minute.
(g) Check the connected portions of each hose and pipe.
(h) Check the installed parts on the fuel tank.
If any malfunctions, damage or other problems are found, replace the fuel tank and filler pipe.






(i) Reconnect the vent line hose to the fuel vapor containment valve.
(1) Push the vent hose into the fuel vapor containment valve port and push the retainer to lock it.
NOTICE:
- Check for damage or foreign objects on the connected part.
- After connecting, check that the vent hose and the valve are securely connected by pulling on them.

6. CHECK FUEL CUTOFF VALVE AND FILL CHECK VALVE






(a) Press the lid switch to release the pressure in the fuel tank.
(b) Check that the lid is opened.
(c) Disconnect the vent line hose from the fuel vapor containment valve.





(d) Connect the pressure gauge to the vent line hose.
(e) Fill the fuel tank with fuel.
(f) Apply pressure of 4 kPa (41 gf/cm2, 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.

(g) Remove the fuel tank cap, and check that the pressure drops.
If the pressure does not drop, replace the fuel tank assembly.
(h) Reconnect the vent line hose to the fuel vapor containment valve.
7. CHECK AIR INLET LINE






(a) Remove floor under cover.
(b) Disconnect the air inlet line hose from the charcoal canister.
(1) Push the hose firmly toward the canister side.
(2) Pinch the hose (portion A) as shown in the illustration.
(3) Pull out the hose.
NOTICE:
- Do not use any tools in this procedure.
- Check for any dirt and foreign matter contamination in the canister and around the hose. Clean if necessary. Foreign matter may damage the O-rings or cause leaks in the seal between the canister and hose.

(c) 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.

(d) Reconnect the air inlet line hose to the charcoal canister.
NOTICE:
- Check for damage or foreign objects on the connected part.
- After connecting, check that the vent hose and the valve are securely connected by pulling on them.

(e) Reinstall the floor under cover.
