DTC
| Component
| Fail-Safe Operation
| Fail Safe Deactivation Condition
|
P0031, P0032, P0051 and P0052
| Air-Fuel Ratio (A/F) Sensor Heater
| ECM turns off A/F sensor heater
| Engine switch off
|
P0037, P0038, P0057 and P0058
| Heated Oxygen Sensor (HO2S) Heater
| ECM turns off HO2 sensor heater
| Engine switch off
|
P0087, P0088
| High Pressure Side Fuel Pump
| - Stop the high pressure side fuel pump
- Limit the engine speed to 2,000 rpm or less
| Pass condition detected
|
P0100, P0102 and P0103
| Mass Air Flow (MAF) Meter
| ECM calculates ignition timing according to engine speed and throttle valve position
| Pass condition detected
|
P0110, P0112 and P0113
| Intake Air Temperature (IAT) Sensor
| ECM estimates IAT to be 20°C (68°F)
| Pass condition detected
|
P0115, P0117 and 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, P0607, P0657, P2102, P2103, P2111, P2112, P2118, P2119 and P2135
| Electronic Throttle Control System (ETCS)
| ECM cuts off throttle actuator current and throttle valve returns to 6.5° 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
|
P0190, P0192, P0193
| Fuel pressure sensor
| - Stop the high side fuel pump
- Limit the engine speed to 2,000 rpm or less
| Pass condition detected and then engine switch turned off
|
P0200, P0201, P0202, P0203, P0204, P0205, P0206, P12FF
| Injector
| - Stop fuel injection for an abnormal cylinder and related other cylinders
- Limit the engine speed to 3,000 rpm or less
| Pass condition detected and then engine switch turned off
|
P0327, P0328, P0332 and P0333
| Knock Sensor
| ECM sets ignition timing to maximum retard.
| Engine switch off
|
P0351 to P0356
| Ignition Coil
| ECM cuts fuel
| Pass condition detected
|
P1235
| High Pressure Side Fuel Pump (spill valve)
| - Stop the high side fuel pump
- Limit the engine speed to 2,000 rpm or less
| Pass condition detected
|
P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138
| Accelerator Pedal Position (APP) Sensor
| APP sensor has 2 sensor circuits: Main and Sub. If either of circuit malfunctions, ECM controls engine using other circuit. If both of circuit malfunction, ECM regards accelerator pedal as being released. As a result, throttle valve is closed and engine idles.
| Pass condition detected and then engine switch turned off
|
