DTC Related Item
| DTC No. | Detected items | Engine operating condition in fail-safe mode | |
|---|---|---|---|
| P0011 P0021 |
Intake valve timing control | The signal is not energized to the intake valve timing control solenoid valve and the valve control does not function. | |
| P0101 P0102 P0103 |
Mass air flow sensor circuit | Engine speed will not rise more than 2, 400 RPM due to the fuel cut. | |
| P0117 P0118 |
Engine coolant temperature sensor circuit | Engine coolant temperature will be determined by ECM based on the following condition. CONSULT displays the engine coolant temperature decided by ECM. | |
| Condition | Engine coolant temperature decided (CONSULT display) | ||
| Just as ignition switch is turned ON or START | 40°C (104°F) | ||
| Approx 4 minutes or more after engine starting | 80°C (176°F) | ||
| Except as shown above | 40 - 80°C (104 - 176°F) (Depends on the time) | ||
| When the fail-safe system for engine coolant temperature sensor is activated, the cooling fan operates while engine is running. | |||
| P0122 P0123 P0222 P0223 P2135 |
Throttle position sensor | The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. Therefore, the acceleration will be poor. |
|
| P0196 P0197 P0198 |
Engine oil temperature sensor | Intake valve timing control does not function. | |
| P0500 | Vehicle speed sensor | The cooling fan operates (Highest) while engine is running. | |
| P0524 | Engine oil pressure |
|
|
| P0605 | ECM | (When ECM calculation function is malfunctioning:) ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. ECM deactivates ASCD operation. |
|
| P0643 | Sensor power supply | ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. | |
| P1805 | Brake switch | ECM controls the electric throttle control actuator by regulating the throttle opening to a small range. Therefore, acceleration will be poor. |
|
| Vehicle condition | Driving condition | ||
| When engine is idling | Normal | ||
| When accelerating | Poor acceleration | ||
| P2100 P2103 |
Throttle control motor relay | ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. | |
| P2101 | Electric throttle control function | ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. | |
| P2118 | Throttle control motor | ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. | |
| P2119 | Electric throttle control actuator | (When electric throttle control actuator does not function properly due to the return spring malfunction:) ECM controls the electric throttle actuator by regulating the throttle opening around the idle position. The engine speed will not rise more than 2, 000 RPM. |
|
| (When throttle valve opening angle in fail-safe mode is not in specified range:) ECM controls the electric throttle control actuator by regulating the throttle opening to 20 degrees or less. |
|||
| (When ECM detects the throttle valve is stuck open:) While the vehicle is being driven, it slows down gradually because of fuel cut. After the vehicle stops, the engine stalls. The engine can restart in the N or P position, and engine speed will not exceed 1, 000 RPM or more. |

| P0102 P0103 P0121 P0121 P1631 |
Accelerator pedal position sensor | The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. Therefore, the acceleration will be poor. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
