Sfi System -- 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.
| DTC | Component | Fail-Safe Operation | Fail-Safe Deactivation Condition |
| P0011, P0021, P0015 and P0025 | Camshaft oil control valve (OCV) |
| Engine switch off |
| P0031, P0032, P0051 and P0052 | Air Fuel Ratio Sensor Heater | ECM turns off the air fuel ratio sensor heater. | Engine switch off |
| P0037, P0038, P0057 and P0058 | Heated Oxygen Sensor Heater | ECM turns off the heated oxygen sensor heater. | Engine switch off |
| P0102 and P0103 | Mass Air Flow Meter Assembly | ECM calculates the ignition timing according to the engine speed and throttle valve position. | Pass condition detected |
| P0112 and P0113 | Intake Air Temperature Sensor | ECM estimates the intake air temperature to be 20°C (68°F). | Pass condition detected |
| P0115, P0117 and P0118 | Engine Coolant Temperature Sensor | ECM estimates the engine coolant temperature to be 80°C (176°F). | Pass condition detected |
| P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0604, P0606, P060A, P060B, P060D, P060E, P0657, P2102, P2103, P2111, P2112, P2118, P2119 and P2135 | Electronic Throttle Control System (ETCS) | ECM cuts off the throttle actuator current and the throttle valve returns to a throttle position of 7° 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 minimal speed.* | Pass condition detected and then engine switch turned off |
| P0327, P0328, P032C, P032D, P0332, P0333, P033C and P033D | Knock Sensor | ECM sets the ignition timing to maximum retard. | Engine switch off |
| P0351 to P0358 | Igniter | ECM cuts the fuel. | Pass condition detected |
| P0504 | Stop Light Switch Assembly | The accelerator pedal opening angle is fixed when there is a accelerator pedal malfunction or history of a malfunction. | Pass condition detected |
| P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138 | Accelerator Pedal Position Sensor Assembly | 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 |
| P2237, P2238, P2239, P2240, P2241, P2242, P2252, P2253, P2255, P2256 | Air Fuel Ratio Sensor |
| Pass condition detected and then engine switch turned off |
| P2432, P2433, P2437 and P2438 | Secondary Air Injection System | Throttle valve opening angle control is performed. | Pass condition detected |
| P2440, P2442, and P2445 | Secondary Air Injection System | Throttle valve opening angle control is performed. | Pass condition detected |
- HINT:
- *: 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.
