What Does the DTC Code P0223 Mean?
The Diagnostic Trouble Code (DTC) P0223 signals a high voltage input from the Throttle/Pedal Position Sensor/Switch ‘B’ Circuit. This code is triggered when the Engine Control Module (ECM) detects that the voltage from the throttle position sensor exceeds the manufacturer’s specified range.
How Serious Is the DTC Code P0223?
The severity of the P0223 code can vary. While it might not be immediately critical, it can lead to significant drivability issues such as limited acceleration or engine stalling. If ignored, it can escalate into more severe problems. Therefore, prompt diagnosis and repair are advisable.
Is It Safe to Drive with the DTC Code P0223?
Driving with the P0223 code is generally not recommended. The vehicle may enter “limp mode,” severely limiting engine performance and creating potentially dangerous driving conditions. Immediate attention is required to prevent further damage and ensure safe vehicle operation.

- Throttle Position Sensor: $100 – $300
- Throttle Body: $200 – $600
- Wiring Repairs: $50 – $200
- Engine Control Module: $500 – $1,500
Labor costs can add an additional $100 – $200, depending on the complexity of the repair and local labor rates.
How to Reset the DTC Code P0223
Yes, you can reset the P0223 code yourself using an OBD-II scanner. Here’s how:
- Connect the Scanner: Plug the OBD-II scanner into the vehicle’s diagnostic port.
- Read Codes: Turn on the ignition and use the scanner to read the stored codes.
- Clear Codes: Follow the scanner’s instructions to clear the codes from the ECM.
However, resetting the code without addressing the underlying issue will likely result in the code reappearing.
