P2260 Mercury Code - Secondary Air Injection System Control 'B' Circuit High
Quick Answer
The P2260 diagnostic trouble code (DTC) for Mercury vehicles refers to an issue with the Secondary Air Injection System Control 'B' Circuit High. Common causes include Faulty Secondary Air Injection Pump: A malfunctioning secondary air injection pump can cause the control circuit to detect high voltage signals, Defective Air Injection Solenoid: Issues with the air injection solenoid can also trigger the P2260 code, Wiring Issues: Damaged or corroded wiring connections related to the secondary air injection system can lead to circuit high voltage problems. 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 P2260 Mercury Description
The P2260 diagnostic trouble code (DTC) for Mercury vehicles refers to an issue with the Secondary Air Injection System Control 'B' Circuit High. The secondary air injection system plays a crucial role in reducing harmful emissions by injecting fresh air into the exhaust system during certain driving conditions. This helps in burning any unburned fuel in the exhaust gases before they are released into the atmosphere.
Common Causes of P2260 Mercury
- Faulty Secondary Air Injection Pump: A malfunctioning secondary air injection pump can cause the control circuit to detect high voltage signals.
- Defective Air Injection Solenoid: Issues with the air injection solenoid can also trigger the P2260 code.
- Wiring Issues: Damaged or corroded wiring connections related to the secondary air injection system can lead to circuit high voltage problems.
- Vacuum Leaks: Vacuum leaks in the system can disrupt the proper functioning of the secondary air injection system and trigger the code.
- PCM/ECU Malfunction: A malfunction in the powertrain control module (PCM) or engine control unit (ECU) could also be a possible cause for the code.
Symptoms of P2260 Mercury
- Check Engine Light: The most common symptom associated with the P2260 code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: A rough or unstable idle may occur due to improper air-fuel mixture caused by the malfunctioning secondary air injection system.
- Decreased Performance: The vehicle may experience a decrease in performance, such as reduced acceleration or power output.
- Increased Emissions: High emissions levels may be detected during emissions testing, indicating a problem with the secondary air injection system.
- Engine Misfires: Misfires or hesitation during acceleration can also be a symptom of this issue.
How to Fix P2260 Mercury
- Diagnostic Check: Begin by performing a thorough diagnostic check to pinpoint the exact cause of the P2260 code.
- Inspect Components: Inspect the secondary air injection pump, air injection solenoid, and wiring connections for any signs of damage or malfunction.
- Repair or Replace Parts: Depending on the findings, repair or replace any faulty components such as the pump, solenoid, or wiring.
- Clear Codes: After the repairs have been made, clear the diagnostic trouble codes and reset the vehicle's engine control module.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that no further symptoms are present.
Cost to Fix P2260 Mercury
