If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.
| DTC No. | Component | Fail-Safe Operation | Fail-Safe Deactivation Condition |
|---|---|---|---|
| P0100, P0102 and P0103 | Mass Air Flow (MAF) Meter | The ECM calculates ignition timing according to the engine speed and throttle valve position. | Pass condition detected |
| P0110, P0112 and P0113 | Intake Air Temperature (IAT) Sensor | The ECM estimates the IAT to be 20°C (68°F). | Pass condition detected |
| P0115, P0117 and P0118 | Engine Coolant Temperature (ECT) Sensor | The ECM estimates the ECT to be 80°C (176°F). | Pass condition detected |
| P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0604, P0606, P0607, P0657, P2102, P2103, P2111, P2112, P2118, P2119 and P2135 | Electronic Throttle Control System (ETCS) | The ECM cuts off throttle actuator current 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 fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal position to allow the vehicle to continue at minimal speed*. |
Pass condition detected and then engine switch turned off |
| P0327 and P0328 | Knock Sensor | The ECM sets the ignition timing to maximum retard. | Engine switch off |
| P0351, P0352, P0353 and P0354 | Igniter | The ECM cuts the fuel. | Pass condition detected |
| P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138 | Accelerator Pedal Position (APP) Sensor | The APP sensor has 2 sensor circuits: Main and Sub. If either circuit malfunctions, the ECM controls the engine using the other circuit. 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 |
Note
*: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly. If the accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.
