When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the fault code P1443.

This code indicates a problem with the Evaporative Emission Control System. It specifically points to a malfunction in the Purge Control Solenoid Valve. The Purge Control Solenoid Valve is responsible for controlling the flow of fuel vapor from the charcoal canister to the engine intake manifold.

When this valve malfunctions, it can lead to issues with the fuel vapor management system, causing the Engine Light to illuminate. If you encounter the P1443 fault code, it is important to address it promptly. Ignoring this issue can result in decreased fuel efficiency and increased emissions. To fix this problem, you will need to inspect the Purge Control Solenoid Valve and its associated wiring for any signs of damage or disconnection.

Replacing the faulty valve or repairing the wiring should resolve the issue and turn off the Engine Light.

Remember, addressing this fault code promptly will help maintain the optimal performance of your vehicle.
