P0010, P0020, P1023, P1360, P1361, P1362, P1363, P2614
| Camshaft timing control motor
| - Power to camshaft timing control motor is cut
- Valve timing of bank that is operating normally is fixed at maximum retard angle
| Pass condition detected and then engine switch turned off
|
P0011, P0012, P0021, P0022
| VVT system
| - Idling up (misfire prevention), or power to camshaft timing control motor is cut
- Valve timing of bank that is operating normally is fixed at maximum retard angle
| 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
| - Power to camshaft timing control motor is cut
- Valve timing of bank that is operating normally is fixed at maximum retard angle
| 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
|
P0097, P0098, P0112, P0113
| Intake Air Temperature (IAT) Sensor
| - If sensor on one side is malfunctioning, temperature detected by normal sensor is used for control
- If both sensors are malfunctioning, ECM estimates IAT to be 20°C (68°F)
| 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, P0607, P0657, 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
|
P0171, P0172, P0174, P0175
| Fuel trim
| Air-fuel ratio feedback control is stopped
| 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
| 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
