Fuel Volume Regulator Solenoid Supply Voltage Control Circuit/Open

Descripción

This code signifies an issue with the electrical circuit of the fuel volume regulator solenoid, specifically an open circuit. This solenoid is crucial for controlling the amount of fuel delivered to the engine, and an open circuit means it's not receiving power.

Pasos de reparación

1. 1 Check the fuse related to the fuel volume regulator solenoid circuit and replace if blown.
2. 2 Inspect the electrical connector at the fuel volume regulator solenoid for looseness, corrosion, or damage, and clean or reseat as needed.
3. 3 Inspect the wiring harness between the ECM and the fuel volume regulator solenoid for open circuits, chafing, or damaged wires, and repair as necessary.
4. 4 Test the fuel volume regulator solenoid supply voltage with a multimeter to verify proper voltage is reaching the solenoid.
5. 5 Replace the fuel volume regulator solenoid if testing confirms it has failed or has excessive resistance.
6. 6 Have the engine control module (ECM) professionally diagnosed and replaced if all wiring, connectors, and the solenoid test normal.
