Code P0222 2004 Toyota Prius Description
The P0222 diagnostic trouble code (DTC) for a 2004 Toyota Prius indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit, specifically a low input signal. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve, which regulates the amount of air entering the engine. The TPS sends this information to the engine control module (ECM), allowing it to adjust fuel delivery and ignition timing accordingly.
Common Causes of P0222 2004 Toyota Prius
- Faulty throttle position sensor
- Wiring issues or poor electrical connections
- ECM software malfunction
- Throttle body problems
- Environmental factors such as moisture or corrosion

- Rough idling or stalling
- Poor acceleration or hesitation
- Reduced engine power
- Engine misfires
- Limp mode activation
How to Fix P0222 2004 Toyota Prius
- Begin by conducting a thorough inspection of the throttle position sensor and its wiring harness for any visible damage or corrosion.
- Test the TPS using a multimeter to check for proper voltage output at various throttle positions.
- If the TPS is faulty, replace it with a new sensor following the manufacturer's guidelines.
- Check and repair any damaged wiring or connectors in the TPS circuit.
- Clear the DTC using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
