FAIL-SAFE

When any of these DTCs as well as other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator and the throttle valve is returned to a 6.5° opening angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal position to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

The ECM continues operating in fail-safe mode until a pass condition is detected and the ignition switch is turned off.

HINT: The Control the Injection Volume for A/F sensor operation lowers the fuel injection volume by 12.5% or increases the injection volume by 25%. Each sensor reacts in accordance with increases and decreases in the fuel injection volume. Standard Tester Display (Sensor) Injection Volume Status Voltage AFS Voltage B1S1 (Air fuel ratio sensor) +25% Rich Below 3.1 V AFS Voltage B1S1 (Air fuel ratio sensor) -12.5% Lean Higher than 3.4 V O2S B1S2 (Heated oxygen sensor) +25% Rich Higher than 0.55 V O2S B1S2 (Heated oxygen sensor) -12.5% Lean Below 0.4 V RESULT Status of AFS Voltage B1S1 Status of O2S B1S2 A/F Condition and A/F and HO2 Sensor Condition Misfire Main Suspected Trouble Area Proceed to Lean/Rich Lean/Rich Normal - Three Way Catalytic Converter (TWC) Gas leak from exhaust system A Lean Lean/Rich Air fuel ratio sensor malfunction - Air fuel ratio sensor B Rich Lean/Rich Air fuel ratio sensor malfunction - Air fuel ratio sensor Lean/Rich Lean Heated oxygen sensor malfunction - Heated oxygen sensor Gas leak from exhaust system C Lean/Rich Rich Heated oxygen sensor malfunction - Heated oxygen sensor Gas leak from exhaust system Lean Lean Actual air fuel ratio lean May occur Extremely rich or lean actual air fuel ratio Gas leak from exhaust system D Rich Rich Actual air fuel ratio rich - Extremely rich or lean actual air fuel ratio Gas leak from exhaust system Lean: During Control the Injection Volume for A/F sensor, the air fuel ratio sensor output voltage (AFS) is consistently higher than 3.4 V, and the heated oxygen sensor output voltage (O2S) is consistently below 0.4 V. Rich: During Control the Injection Volume for A/F sensor, the AFS voltage is consistently below 3.1 V, and the O2S voltage is consistently higher than 0.55 V. Lean/Rich: During Control the Injection Volume for A/F sensor of the Active Test, the output voltages of the air fuel ratio sensor and heated oxygen sensor alternate correctly.

3. INSPECT FOR EXHAUST GAS LEAK Inspect for exhaust gas leakage. OK No gas leakage. NG --> REPAIR OR REPLACE EXHAUST GAS LEAK POINT OK: Go to next step
4. REPLACE FRONT EXHAUST PIPE ASSEMBLY (TWC: FRONT CATALYST AND REAR CATALYST) Replace the front exhaust pipe assembly, refer to «REMOVAL»(ref-422105-S03173197242011092600000) . NEXT: Go to next step
5. CHECK WHETHER DTC OUTPUT RECURS Connect the Techstream to the DLC3. Turn the ignition switch to ON and turn the Techstream on. Clear the DTCs, refer to «DTC CHECK / CLEAR»(ref-421953-S17634125332011092600000) . Drive the vehicle at a speed between 64 km/h and 113 km/h (40 mph and 70 mph) for at least 10 minutes. Enter the following menus: Powertrain / Engine / DTC. Read the DTCs (Pending DTCs). Result Pending DTC is not output NEXT --> END
6. GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-421953-S08108164442011092600000)
7. REPLACE AIR FUEL RATIO SENSOR. Refer to «REMOVAL»(ref-421955-S25491508152011092600000)
8. CHECK EXTREMELY RICH OR LEAN ACTUAL AIR FUEL RATIO, REPAIR CAUSE AND GO TO STEP 3. Refer to «DTC P0171: System Too Lean (Bank 1); DTC P0172: System Too Rich (Bank 1)»(ref-422141-S29714303582011092600000)
9. INSPECT FOR EXHAUST GAS LEAK Inspect for exhaust gas leakage. OK No gas leakage. NG --> REPAIR OR REPLACE EXHAUST GAS LEAK POINT OK --> See step 10
10. REPLACE HEATED OXYGEN SENSOR. Refer to «REMOVAL»(ref-421955-S02330336742011092600000)
