1. INSPECT AIR-FUEL RATIO COMPENSATION SYSTEM
(a) Measure the voltage between the terminals of the ECM connectors.
Standard:
NOTICE: Connect test leads to the connector's backside. The connectors should not be disconnected from the ECM.
HINT: Voltage between the terminals of the ECM is kept constant regardless of the voltage of the A/F sensor.
(b) Connect the hand-held tester to the DLC3.
(c) Select "DATA MONITOR". Then select "A/FS B1 S1", "A/FS B2 S1" and "O2S B1 S2" to display the monitors.
(d) Warm up the A/F sensor with the engine speed at 2,500 rpm for approximately 2 minutes.
(e) Keep the engine speed at 2,500 rpm and confirm that the displays of "A/FS B1 S1" and "A/FS B2 S1" are as shown in the illustration.
HINT:
(f) Confirm that the display of "O2S B1 S2" changes between 0 to 1 V with the engine speed at 2,500 rpm.
2. INSPECT FUEL CUT OFF/RESTART RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for the injector operating noise.
(c) When the accelerator pedal is released, injector operating noise stops momentarily and then resumes.
Standard:
If the result is not as specified, check for DTCs. If a DTC is present, follow the repair procedures according to the DTC.
3. VISUALLY INSPECT HOSES, CONNECTIONS 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.
Be sure to check the areas indicated by the arrow marks.
If necessary, replace any damage parts.
4. Using hand-held tester: INSPECT EVAP SYSTEM LINE
(a) Warm up and stop the engine.
(b) Install a vacuum gauge (EVAP control system test equipment vacuum gauge) to the EVAP service port on the purge line.
(c) Connect the hand-held tester to the DLC3.
(d) Start the engine.
(e) Turn the hand-held tester main switch ON.
(f) Use the ACTIVE TEST mode on the hand-held tester to operate the VSV for EVAP.
(g) Check the vacuum while the engine is idling.
Standard: Maintain at 0.368 to 19.713 in.Hg (5 to 268 in.Aq) for over 5 seconds.
HINT: If the vacuum does not change, the hose connecting the VSV to the service port has come loose or is blocked, or the VSV is malfunctioning.
(h) Stop the engine.
(i) Disconnect the hand-held tester from the DLC3.
(j) Disconnect the vacuum gauge from the EVAP service port on the purge line.
(k) Connect a pressure gauge to the EVAP service port on the purge line.
(l) Connect the hand-held tester to the DLC3.
(m) Turn the ignition switch ON.
(n) Turn the hand-held tester main switch ON.
(o) Use the ACTIVE TEST mode on the hand-held tester to operate the VSV for CCV.
NOTICE: In step (m), the ignition switch should be ON, but the engine should not be running.
HINT: If the check is not completed within 10 minutes, the VSV for CCV will be reset and close automatically.
(p) Check the pressure.
Standard: 2 minutes after the pressure is added, the gauge should still read over 7.7 to 8.8 in.Aq.
HINT: If you cannot add pressure, the hose connecting the VSV for EVAP canister fuel tank has become disconnected or the VSV is open.
HINT: If the pressure does not decrease when the fuel tank cap is removed, the hose connecting the service port to the fuel tank is blocked.
(q) Turn the ignition switch OFF.
(r) Disconnect the hand-held tester from the DLC3.
5. Not using hand-held tester: INSPECT EVAP SYSTEM LINE
(a) Warm up and stop the engine.
(b) Install a vacuum gauge (EVAP control system test equipment vacuum gauge) to the EVAP service port on the purge line.
(c) Disconnect the VSV connector for EVAP.
(d) Connect the battery's positive (+) and negative (-) leads to the VSV terminals for EVAP.
(e) Start the engine.
(f) Check the vacuum while the engine is idling.
Standard: Maintain at 0.368 to 19.713 in.Hg (5 to 268 in.Aq) for over 5 seconds.
HINT: If the vacuum does not change, the hose connecting the VSV to the service port has come loose or is blocked, or the VSV is malfunctioning.
(g) Stop the engine.
(h) Disconnect the battery's positive (+) and negative (-) leads from the VSV terminals for EVAP.
(i) Reconnect the VSV connector for EVAP.
(j) Disconnect the vacuum gauge from the EVAP service port on the purge line.
(k) Connect a pressure gauge to the EVAP service port on the purge line.
(l) Disconnect the VSV connector for CCV.
(m) Connect the battery's positive (+) and negative (-) leads to the VSV terminals for CCV.
NOTICE: Incorrect electrode connection causes damage to the VSV.
Pay due attention when connecting the lead wire.
(n) Check the pressure.
Standard: 2 minutes after the pressure is added, the gauge should still read over 7.7 to 8.8 in.Aq.
HINT: If you cannot add pressure, the hose connecting the VSV for EVAP canister fuel tank has become disconnected or the VSV is open.
HINT: If the pressure does not decrease when the fuel tank cap is removed, the hose connecting the service port to the fuel tank is blocked.
(o) Disconnect the battery's positive (+) and negative (-) leads from the VSV terminals for CCV.

(c) Apply pressure to the fuel tank to create an internal pressure of 4 kPa (41 gf/cm2, 0.58 psi).
(d) Check that the internal pressure of the fuel tank is maintained for 1 minute.
v (e) Check the connected portions of each hose and pipe.
(f) Check the installed parts on the fuel tank.

(c) Fill the fuel tank with fuel.
(d) Apply pressure of 4 kPa (41 gf/cm2, 0.58 psi) to the vent port of the fuel tank.
HINT: It is necessary to 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 pressure drops.
If pressure does not drop, replace the fuel tank assembly.
(f) Reconnect the vent line hose to the fuel tank.
8. CHECK AIR INLET LINE
