Fuel Volume Regulator Solenoid Supply Voltage Control Circuit Low

Descripción

This code means the voltage in the electrical circuit for the fuel volume regulator solenoid is too low. This can prevent the solenoid from working correctly, leading to improper fuel delivery and potentially affecting engine performance.

Pasos de reparación

1. 1 Check battery voltage and ensure it is within specification (12.4V+ with engine off, 13.5-14.5V with engine running); charge or replace the battery if low.
2. 2 Inspect the electrical connector at the fuel volume regulator solenoid for corrosion, loose pins, or damage; clean and reseat the connector.
3. 3 Check the wiring harness between the ECM and the fuel volume regulator solenoid for chafed, broken, or shorted wires; repair any damaged wiring.
4. 4 Measure the supply voltage at the fuel volume regulator solenoid connector with a multimeter to confirm low voltage condition and isolate the source of the voltage drop.
5. 5 Inspect the ground connections related to the fuel volume regulator circuit; clean and tighten any corroded or loose grounds.
6. 6 Replace the fuel volume regulator solenoid if the wiring and connections test good but the circuit still reads low voltage.
7. 7 Have the engine control module (ECM) tested and reprogrammed or replaced if all other components and wiring in the circuit test normal.
