If any of the following DTCs are set, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.
| DTC | Component | Fail-safe Operation | Fail-safe Deactivation Condition |
|---|---|---|---|
| P0010, P0020, P1023, P1360, P1361, P1362, P1363, P2614 | Camshaft timing control motor |
|
Pass condition detected and then engine switch turned off |
| P0011, P0012, P0021, P0022 | VVT system |
|
Pass condition detected and then engine switch turned off |
| P0015, P0025 | Exhaust camshaft oil control valve | Idling up | Pass condition detected |
| P0016, P0017, P0018, P0019 | Valve timing deviation |
|
Pass condition detected and then engine switch turned off |
| P0031, P0032, P0051 and P0052 | Heated Oxygen Sensor (sensor 1) Heater | ECM turns off HO2 sensor heater | Engine switch off |
| P0037, P0038, P0057, P0058 | Heated Oxygen Sensor (sensor 2) Heater | ECM turns off HO2 sensor heater | Engine switch off |
| P0102, P0103, P010C, P010D | Mass Air Flow (MAF) Meter | ECM calculates ignition timing according to engine speed and throttle valve position | Pass condition detected |
| P00AC, P00AD, P0112, P0113 | Intake Air Temperature (IAT) Sensor |
|
Pass condition detected |
| P0115, P0117, P0118 | Engine Coolant Temperature (ECT) Sensor | ECM estimates ECT to be 80°C (176°F) | Pass condition detected |
| P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0604, P0606, P060A, P060B, P060D, P060E, P0657, P1607, P2102, P2103, P2111, P2112, P2118, P2119, P2135 | Electronic Throttle Control System (ETCS) | ECM cuts off throttle actuator current and throttle valve returns to 7° throttle position by return spring. ECM then adjusts engine output by controlling fuel injection (intermittent fuel-cut) and ignition timing in accordance with accelerator pedal opening angle to allow vehicle to continue at minimal speed*. | Pass condition detected and then engine switch turned off |
| P0327, P0328, P0332, P0333 P032C, P032D, P033C, P033D | Knock Sensor | ECM sets ignition timing to maximum retard. | Engine switch off |
| P0351 to P0358 | Igniter | ECM cuts fuel | Pass condition detected |
| P0504 | Stop light switch | Accelerator pedal angle is fixed | Pass condition detected |
| P2120, P2121, P2122, P2123, P2125, P2127, P2128, P2138 | Accelerator Pedal Position (APP) 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 |
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.
