If any of the following DTCs are recorded, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.
| DTC No. | Component | Fail-Safe Operation | Fail-Safe Deactivation Condition |
|---|---|---|---|
| P0112 and P0113 | Intake Air Temperature sensor | ECM assumes that IAT is 20°C (68°F) | Pass condition detected |
| P0117 and P0118 | Engine Coolant Temperature sensor | ECM performs engine control using estimated ECT calculated from IAT at time of engine start and intake air volume | Pass condition detected |
| P0121, P0122, P0123, P0221, P0222 or P0223 | Throttle Position sensor | ECM limits its accelerator pedal position sensor value to below 40%. | Pass condition detected and ignition switch off |
| P0301, P0302 and P0303 | Misfire detected | If misfire rate of cylinder exceeds catalytic damage misfire rate, fuel supply to that cylinder is suspended | Pass condition detected |
| P0327 | Knock sensor | ECM sets ignition timing to maximum retard | Pass condition detected |
| P0400 | Exhaust Gas Recirculation Flow | ECM assumes that EGR valve is closed, so that ignition angle is controlled with safety valve | Pass condition detected |
| P0403 | Exhaust Gas Recirculation Control Circuit | Pass condition detected | |
| P2111, P2101, P2102, P2103, P2118, P2129, P2109, P0606 | Throttle control system | Power source of throttle control motor shut down, and engine speed is limited by fuel cut. | Pass condition detected and ignition switch off |
| P2122, P2123, P2128, P2127 or P2138 | Accelerator position sensor | ECM limits its accelerator pedal position sensor value below 40%. | Pass condition detected and ignition switch off |
| "P2122 or P2123" and "P2128 or P2127 " | Accelerator position sensor | Drive with "First idle" condition | Pass condition detected and ignition switch off |
