Fuel Injector Insufficient Flow - Forced Limited Power

Descripción

This code indicates that one or more fuel injectors are not delivering enough fuel to the engine. The engine's computer is forcing it to limit power to protect itself from damage.

Pasos de reparación

1. 1 Check for other related diagnostic trouble codes (DTCs) such as misfire codes or fuel pressure codes that may help pinpoint the affected cylinder(s) or system.
2. 2 Inspect fuel injector electrical connectors and wiring for damage, corrosion, or loose connections.
3. 3 Check fuel pressure using a fuel pressure gauge to verify it meets manufacturer specifications; low pressure may indicate a fuel pump or fuel filter issue.
4. 4 Add a professional-grade fuel injector cleaner to the fuel tank and drive for a full tank cycle to attempt clearing minor injector deposits.
5. 5 Inspect and replace the fuel filter if it is clogged or has not been replaced per the maintenance schedule.
6. 6 Test fuel injectors individually using a noid light or injector pulse tester to identify any that are not firing or flowing properly.
7. 7 Have the fuel injectors professionally cleaned using an ultrasonic cleaning service or on-car pressurized cleaning system.
8. 8 Replace any faulty or clogged fuel injectors that do not respond to cleaning.
9. 9 Test and replace the fuel pump if fuel pressure is consistently below specification and the fuel filter has been ruled out.
