INSPECTION PROCEDURE

HINT

1. Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
2. The throttle actuator current (Throttle Motor Current) and the throttle actuator duty ratio (Throttle Motor Duty (Open) / Throttle Motor Duty (Close)) can be read using the Techstream. However, the ECM shuts off the throttle actuator current when the electronic throttle control system malfunctions.

Malfunctioning areas can be identified by performing the Control the Injection Volume for A/F Sensor function provided in the Active Test. The Control the Injection Volume for A/F Sensor function can help to determine whether the air fuel ratio sensor, heated oxygen sensor and other potential trouble areas are malfunctioning.

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P2195, P2196, 2197 OR P2198) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Read the DTCs.

B --> See step 18 A: Go to next step
2. READ VALUE USING TECHSTREAM (TEST VALUE OF AIR FUEL RATIO SENSOR) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear the DTCs. Refer to «DTC CHECK / CLEAR»(ref-394619-S02527777542011040800000). Allow the vehicle to drive in accordance with the driving pattern described in the Confirmation Driving Pattern. Enter the following menus: Powertrain / Engine / Monitor / O2 Sensor. Check that the status of O2 Sensor is Complete. If the status is still Incomplete, drive the vehicle according to the driving pattern again. Enter the following menus: Powertrain / Engine / Monitor / O2 Sensor / Details / RANGE B1S1 or RANG B2S1 / Details. Check the test value of the air fuel ratio sensor output current during fuel cut. Result Test Value Proceed to Within normal range (1.4 mA or more, and less than 3.6 mA) A Outside normal range (Less than 1.4 mA, or 3.6 mA or more) B B --> See step 15 A: Go to next step
3. READ VALUE USING TECHSTREAM (OUTPUT VOLTAGE OF AIR FUEL RATIO SENSOR) Connect the Techstream to the DLC3. Start the engine. Turn the Techstream on. Warm up the air fuel ratio sensor at an engine speed of 2500 rpm for 90 seconds. Enter the following menus: Powertrain / Engine / Data List / A/F Control System / AFS Voltage B1S1 or AFS Voltage B2S1 and Engine Speed. Check the air fuel ratio sensor voltage 3 times, when the engine is in each of the following conditions: While idling (check for at least 30 seconds) (Step "A") At an engine speed of approximately 2500 rpm (without any sudden changes in engine speed) (Step "B") Raise the engine speed to 4000 rpm and then the accelerator pedal is quickly released so that the throttle valve is fully closed (Step "C"). Standard Condition Air Fuel Ratio Sensor Voltage Variation Reference Step "A" and "B" Changes at approximately 3.3 V Between 3.1 V and 3.5 V Step "C" Increases to 3.8 V or more This occurs during engine deceleration (when fuel cut performed) HINT: For more information, see the diagrams below. If the output voltage of the air fuel ratio sensor remains at approximately 3.3 V (Scheme 330) under any conditions, including those above, the air fuel ratio sensor may have an open circuit. (This will also happen if the air fuel ratio sensor heater has an open circuit.) If the output voltage of the air fuel ratio sensor remains at either approximately 3.8 V or more, or 2.8 V or less (Scheme 330) under any conditions, including those above, the air fuel ratio sensor may have a short circuit. The ECM stops fuel injection (fuel cut) during engine deceleration. This causes a lean condition and results in a momentary increase in the air fuel ratio sensor output voltage. The ECM must establish a closed throttle valve position learning value to perform fuel cut. If the battery terminal has been reconnected, the vehicle must be driven over 10 mph (16 km/h) to allow the ECM to learn the closed throttle valve position. When the vehicle is driven: The output voltage of the air fuel ratio sensor may be below 2.8 V during fuel enrichment. For the vehicle, this translates to a sudden increase in speed with the accelerator pedal fully depressed when trying to overtake another vehicle. The air fuel ratio sensor is functioning normally. The air fuel ratio sensor is a current output element; therefore, the current is converted into a voltage inside the ECM. Measuring the voltage at the connectors of the air fuel ratio sensor or ECM will show a constant voltage result. NG --> See step 10 OK: Go to next step

1. DTC P2A00 or P2A03 may also be set when the air fuel ratio remains rich or lean.
2. A low air fuel ratio sensor voltage could be caused by a rich air fuel mixture. Check for conditions that would cause the engine to run rich.
3. A high air fuel ratio sensor voltage could be caused by a lean air fuel mixture. Check for conditions that would cause the engine to run lean.
4. Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

Note. Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Scheme 377

Scheme 378

1. PERFORM ACTIVE TEST USING TECHSTREAM (ACTIVATE THE VSV FOR AICS) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for AICS. Check the operation of the VSV when the VSV is operated using the Techstream. Standard Techstream Operation Specified Condition ON Air from port E flows out through port F OFF Air from port E flows out through the air filter NG --> See step 2 OK --> PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE
2. CHECK VACUUM SWITCHING VALVE (FOR AIR INTAKE CONTROL VALVE) Check the vacuum switching valve for air intake control valve. Refer to «ON-VEHICLE INSPECTION»(ref-394807-S40547566282011040800000) . NG --> REPLACE AIR CLEANER ASSEMBLY OK: Go to next step
3. CHECK HARNESS AND CONNECTOR (VSV FOR AIR INTAKE CONTROL VALVE POWER SOURCE) Disconnect the vacuum switching valve for air intake control valve connector. Turn the ignition switch to ON. Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Switch Condition Specified Condition A8-1 - Body ground Ignition switch ON 11 to 14 V TEXT IN ILLUSTRATION *1 Front view of wire harness connector (to Vacuum Switching Valve for Air Intake Control Valve) NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR (ENGINE ROOM JUNCTION BLOCK ASSEMBLY - VACUUM SWITCHING VALVE) OK: Go to next step
4. CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE FOR AIR INTAKE CONTROL VALVE - ECM) Disconnect the vacuum switching valve for air intake control valve connector. Disconnect the ECM connector. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition A8-2 - B39-61 (AICV) Always Below 1 ohms Standard Resistance (Check for Short) Tester Connection Condition Specified Condition A8-2 or B39-61 (AICV) - Body ground Always 10 kohms or higher Reconnect the ECM connector. Reconnect the vacuum switching valve for air intake control valve connector. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR (VACUUM SWITCHING VALVE FOR AIR INTAKE CONTROL VALVE - ECM) OK: Go to next step
5. INSPECT VACUUM SURGE TANK Inspect the vacuum surge tank. Refer to «ON-VEHICLE INSPECTION»(ref-394807-S18701682532011040800000) . NG --> REPAIR OR REPLACE AIR CLEANER CAP SUB-ASSEMBLY OK --> See step 6
6. REPLACE ECM. Refer to «REMOVAL»(ref-394792-S25581811582011040800000)
