7 Engine Components That Directly Increase Fuel Consumption

Описание: In today’s video, we break down 7 critical components that can directly increase fuel consumption when they fail, along with how to diagnose each one accurately.
Modern engine management systems rely heavily on sensors and fuel control components to maintain the correct air-fuel ratio. When even one of these parts malfunctions, the ECU may enrich the mixture unnecessarily—leading to poor fuel economy, rough operation, and long-term engine damage.
In this video, you’ll learn:
•How faulty oxygen sensors affect fuel trims
•The role of MAF and MAP sensors in fuel calculation
•Why a bad engine coolant temperature sensor causes rich mixtures
•How a failed fuel pressure regulator increases injector flow
•The impact of fuel injector leakage or clogging
•How a stuck EVAP purge valve wastes fuel
•Why a failed thermostat keeps the engine in cold mode
Each component is explained clearly with real diagnostic logic, not guesswork—exactly how professional technicians approach fuel consumption problems.
If you’re struggling with high fuel usage, this video will help you pinpoint the real cause instead of replacing parts blindly.
