This code means there's a problem with a part in your car that helps control how air is mixed with fuel in the engine. It's like when a toy's battery connection is loose, and it doesn't work right.
The P1287 code indicates an electrical issue with the solenoid that controls the air injection valves on the second bank of the engine.
The P1287 code is triggered when the Engine Control Module (ECM) detects a malfunction in the electrical circuit of the switching solenoid responsible for controlling the air-assisted injection valves on Bank 2. This solenoid helps manage the air-fuel mixture for optimal combustion efficiency.
• Check Engine Light is on
• Decreased engine performance
• Poor fuel economy
• Faulty switching solenoid
• Damaged wiring or connectors
• ECM malfunction
Solenoid: An electromechanical device that controls a valve or switch.
ECM: Engine Control Module, the computer that manages engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the solenoid for proper operation.
• Replace the faulty solenoid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Engine Performance
• Address the issue promptly to avoid further damage.
• Consult a professional mechanic if unsure.
Check with your vehicle manufacturer for specific warranty coverage related to emissions components.
This code has been associated with vehicles that have complex air-fuel management systems, particularly in models with advanced emission controls.
Moderate – Addressing this issue can prevent further engine performance problems.
Driving with this code may lead to increased emissions, which could be against local regulations.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The solenoid is typically located near the intake manifold on the engine's Bank 2.
Q: Can I drive with a P1287 code?
A: It's possible, but not recommended as it may lead to further engine issues.
Q: How do I reset the P1287 code?
A: After repairs, use an OBD-II scanner to clear the code.
