Hi, this is Bo, an auto expert on RepairPal's Car Genius team!
The codes you're dealing with—P0121 and P2102—relate to the throttle system.
- **P0121** refers to a problem with the **Throttle/Pedal Position Sensor/Switch A Circuit Range/Performance**. This typically means there's an issue with how the throttle position sensor is reading or communicating with the engine control module (ECM). It could be a faulty sensor, wiring issue, or a problem with the throttle body itself.
- **P2102** is related to the **Throttle Actuator Control Motor Circuit Range/Performance**. This suggests a problem with the motor that controls throttle movement, usually the throttle body actuator motor.
Together, these codes often point to an issue in the throttle control system, which can cause poor engine performance or stalling.
To fix it, you'd likely need to:
1. Inspect and potentially replace the throttle position sensor.
2. Check the wiring for any shorts, damage, or corrosion.
3. Clean or replace the throttle body if necessary.
4. If the throttle actuator motor is faulty, it may need to be replaced as well.
Clearing the codes without fixing the underlying issue won't resolve the problem. You can clear the codes after the repair to see if they come back.
