P0223 Honda Code - Throttle Position Sensor 'B' Circuit High Voltage
Quick Answer
The P0223 code for Honda vehicles indicates an issue with the Throttle Position Sensor (TPS) 'B' circuit registering high voltage. Common causes include Faulty TPS: A malfunctioning TPS can send incorrect voltage readings to the ECM, triggering the P0223 code, Wiring or connector issues: Damaged or loose wiring or connectors in the TPS circuit can disrupt the signal transmission, leading to high voltage readings, ECM malfunction: An issue with the engine control module can also result in erroneous TPS readings. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0223 Honda Description
The P0223 code for Honda vehicles indicates an issue with the Throttle Position Sensor (TPS) 'B' circuit registering high voltage. The TPS is a crucial component of the vehicle's engine management system, as it helps to monitor the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to adjust the air-fuel mixture and ignition timing for optimal engine performance.
Common Causes of P0223 Honda
- Faulty TPS: A malfunctioning TPS can send incorrect voltage readings to the ECM, triggering the P0223 code.
- Wiring or connector issues: Damaged or loose wiring or connectors in the TPS circuit can disrupt the signal transmission, leading to high voltage readings.
- ECM malfunction: An issue with the engine control module can also result in erroneous TPS readings.
- Throttle body problems: If there are underlying issues with the throttle body, it can affect the TPS readings and trigger the P0223 code.
Symptoms of P0223 Honda
- Loss of power or acceleration: The high voltage reading from the TPS can lead to incorrect fuel delivery, causing a decrease in engine power and acceleration.
- Rough idling or stalling: The ECM may struggle to adjust the air-fuel mixture properly, resulting in rough idling or stalling when the vehicle is at a stop.
- Increased fuel consumption: A faulty TPS can cause the engine to run inefficiently, leading to higher fuel consumption than usual.
- Check Engine Light: The illumination of the Check Engine Light is a common symptom associated with the P0223 code, indicating a problem with the TPS 'B' circuit.
How to Fix P0223 Honda
- Diagnose the issue: Use a diagnostic scanner to confirm the P0223 code and perform further testing to pinpoint the exact cause of the problem.
- Inspect TPS and wiring: Check the TPS for any signs of damage or wear, and inspect the wiring and connectors for any issues.
- Replace TPS: If the TPS is faulty, replace it with a new one following the manufacturer's guidelines.
- Repair wiring or connectors: Repair or replace any damaged wiring or connectors in the TPS circuit to ensure a proper connection.
- Clear codes and test drive: Clear the fault codes from the ECM, and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P0223 Honda
The typical repair costs for addressing a P0223 code on a Honda vehicle can range from $150 to $300, depending on the specific cause of the issue and the cost of parts and labor in your area. It's essential to factor in the diagnosis time and labor rates at local auto repair shops, as these can vary significantly. Keep in mind that rates at dealerships or in metropolitan areas may be higher, while independent shops may offer more competitive prices. To get a precise estimate, it's advisable to contact a few local auto repair shops for quotes.
