Fuel Volume Regulator Solenoid Supply Voltage Control Circuit High

Descripción

This code indicates that the voltage in the electrical circuit for the fuel volume regulator solenoid is too high. This excessive voltage can damage the solenoid or prevent it from functioning correctly, impacting the amount of fuel delivered to the engine.

Pasos de reparación

1. 1 Inspect the wiring and connectors leading to the fuel volume regulator solenoid for damage, chafing, corrosion, or loose connections.
2. 2 Check the supply voltage at the fuel volume regulator solenoid connector using a multimeter to confirm the voltage is reading higher than specification.
3. 3 Inspect the voltage regulator circuit for signs of failure, overheating, or damaged components.
4. 4 Test the fuel volume regulator solenoid resistance and operation to determine if it has failed internally.
5. 5 Repair or replace any damaged wiring or connectors in the fuel volume regulator solenoid supply circuit.
6. 6 Replace the faulty voltage regulator if supply voltage is confirmed out of range.
7. 7 Replace the fuel volume regulator solenoid if it has failed or is not responding correctly to commanded signals.
8. 8 Have the engine control module (ECM) tested and reprogrammed or replaced if all other components test within specification.
