FAIL-SAFE CHART
If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily or stops fuel injection.
DTC Code | Component | Fail-Safe Operation | Fail-Safe Deactivation Condition |
---|---|---|---|
P001100 P001107 P001500 P002100 P002107 P002500 | VVT system |
| Pass condition detected |
P003012 P003013 P005012 P005013 P101A9E P103A9E | Air fuel ratio sensor heater | The ECM turns off the air fuel ratio sensor heater. | Engine switch off |
P003612 P003614 P005612 P005614 P102A9E P105A9E | Heated oxygen sensor heater | The ECM turns off the heated oxygen sensor heater. | Engine switch off |
P008700 P008800 P123513 | Fuel pump assembly (for high pressure side) |
| Engine switch off |
P010012 P010014 | Mass air flow meter sub-assembly | The ECM calculates fuel injection volume according to the engine speed and throttle valve position. | Pass condition detected |
P011011 P011015 | Intake air temperature sensor | The ECM estimates the intake air temperature to be 20°C (68°F). | Pass condition detected and then engine switch turned off |
P011511 P011515 | Engine coolant temperature sensor | The ECM estimates the engine coolant temperature to be 80°C (176°F). | Pass condition detected |
P012011 P012015 P01201C P022011 P022015 P060444 P060604 P060629 P060647 P060A47 P060B49 P060D49 P060E49 P061E49 P065714 P06579E P160700 P210014 P210015 P211172 P211173 P211900 P211904 P211977 P21352B | Electronic throttle control system | The ECM cuts off throttle actuator current and the throttle valve is returned to a 7° throttle position by the return spring. The ECM then adjusts the engine output by controlling fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal angle to allow the vehicle to be driven at a low speed*1. | Pass condition detected and then engine switch turned off |
P019011 P019015 | Fuel pressure sensor (for high pressure) |
| Pass condition detected and then engine switch turned off |
P020113 P020213 P020313 P020413 P020513 P020613 P062D13 | ECM (injector driver) | The ECM performs fuel-cut when the engine speed is 2500 rpm or more. | Pass condition detected and then engine switch turned off |
P030000 P030027 P030085 P030100 P030200 P030300 P030400 P030500 P030600 *2 |
| When a catalyst-damaging misfire occurs (MIL blinking), the following fail-safe operation is performed for catalyst overheat malfunction prevention.
| Pass condition detected and then engine switch turned off |
P032511 P032515 P033011 P033015 | Knock control sensor | The ECM sets the ignition timing to maximum retard. | Engine switch off |
P035113 P035213 P035313 P035413 P035513 P035613 | Ignition coil assembly | The ECM cuts the fuel injection. | Pass condition detected |
P05042B | Stop light switch assembly | The accelerator pedal opening angle is fixed when there is an accelerator pedal malfunction or history of a malfunction. | Pass condition detected and then engine switch turned off |
P056014 | ECM +B circuit | Generator command is maintained. | Pass condition detected and then engine switch turned off |
P107A11 P107A15 | Fuel pressure sensor (for low pressure side) |
| Pass condition detected and then engine switch turned off |
P21CF13 P21D013 P21D113 P21D213 P21D313 P21D413 | Port fuel injector assembly | The ECM performs fuel-cut when the engine speed is 2500 rpm or more. | Pass condition detected and then engine switch turned off |
P212012 P212014 P21201C P21201F P212099 P212512 P212514 P21251F P21382B | Accelerator pedal position sensor | The accelerator pedal position sensor has 2 sensor circuits: Main and Sub. If either circuit malfunctions, the ECM limits the engine output. If both circuits malfunction, the ECM regards the accelerator pedal as being released. As a result, the throttle valve is closed and the engine idles. | Pass condition detected and then engine switch turned off |
P223711 P223712 P223713 P223716 P223717 P22371B P224011 P224012 P224013 P224016 P224017 P22401B P225111 P225112 P225411 P225412 | Air fuel ratio sensor | Air fuel ratio feedback control is stopped | Pass condition detected and then engine switch turned off |
