This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the electrical circuit that controls a valve in the fuel pump. It's like a switch that isn't working right, and it could affect how the car uses fuel.
The P2A87 code indicates an issue with the circuit that controls the compression stroke valve for the alternative fuel pump. This could mean an open circuit or a failure in the control mechanism.
The P2A87 code is triggered when the Engine Control Module (ECM) detects a malfunction in the circuit controlling the compression stroke valve of the alternative fuel pump C. This could be due to an open circuit, a short, or a failure in the control valve itself.
• Check Engine Light is on

Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving long distances until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on fuel system components.
This code has been associated with vehicles using alternative fuel systems, particularly those with complex fuel management systems.
Moderate – Addressing this issue promptly can prevent further engine performance problems.
Driving with a malfunctioning fuel system can lead to increased emissions and potential safety risks.
• Engine running
• Vehicle stationary
The alternative fuel pump is typically located near the fuel tank or engine compartment.
Q: Can I drive my car with a P2A87 code?
A: It's not recommended to drive for long distances as it might affect fuel efficiency and engine performance.
Q: How do I clear a P2A87 code?
A: After repairs, you can clear the code using an OBD-II scanner. However, if the issue persists, the code will reappear.
