P2258 Code - Secondary Air Injection System Control 'A' Circuit High
Quick Answer
The diagnostic trouble code P2258 indicates that there is a problem with the Secondary Air Injection System Control 'A' Circuit being too high. Common causes include Faulty Air Injection Pump: A malfunctioning air injection pump can cause the control circuit to register a high voltage condition, Malfunctioning Air Injection Control Valve: If the control valve is not functioning correctly, it can lead to issues with the circuit, Wiring or Connector Damage: Damaged wiring or connectors in the control circuit can disrupt the flow of electricity and trigger the code. 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 P2258 Description
The diagnostic trouble code P2258 indicates that there is a problem with the Secondary Air Injection System Control 'A' Circuit being too high. The secondary air injection system is responsible for introducing fresh air into the exhaust system to help reduce emissions. When this code is triggered, it means that the control circuit for this system is experiencing a high voltage condition, which can lead to issues with the overall performance of the vehicle.
Common Causes of P2258
- Faulty Air Injection Pump: A malfunctioning air injection pump can cause the control circuit to register a high voltage condition.
- Malfunctioning Air Injection Control Valve: If the control valve is not functioning correctly, it can lead to issues with the circuit.
- Wiring or Connector Damage: Damaged wiring or connectors in the control circuit can disrupt the flow of electricity and trigger the code.
- ECM Malfunction: A problem with the engine control module (ECM) can also cause the circuit to register a high voltage condition.
Symptoms of P2258
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and overall performance.
- Increased Emissions: The vehicle may fail emissions tests or emit excessive pollutants from the exhaust.
- Rough Idle: The engine may idle rough or inconsistently, indicating a potential issue with the air injection system.
- Fuel Efficiency: Reduced fuel efficiency may be observed as a result of the secondary air injection system not functioning properly.
How to Fix P2258
- Diagnostic Check: Begin by performing a thorough diagnostic check to identify the specific cause of the high voltage condition.
- Replace Air Injection Components: Replace any faulty air injection pump, control valve, or damaged wiring or connectors in the circuit.
- Clear Codes: Clear the diagnostic trouble codes from the vehicle's ECM to reset the system.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the check engine light does not reappear.
- Emissions Test: Consider performing an emissions test to verify that the secondary air injection system is functioning correctly and that emissions levels are within acceptable limits.
Cost to Fix P2258
The typical repair costs for addressing the P2258 code can vary depending on the specific cause of the issue and the make and model of the vehicle. On average, the repair costs for this issue can range from $200 to $500, including parts and labor.
