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
| Ignition switch off
|
P0037, P0038, P0057 and P0058
| Heated Oxygen Sensor (HO2S) Heater
| ECM turns off HO2 sensor heater
| Ignition switch off
|
P0087, P0088
| High pressure side fuel pump
| - Stop the high 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

| Electronic Throttle Control System (ECTS)
| 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
|
