Laymans terms

This code means that one of the parts that helps put fuel into the engine is stuck open, letting too much fuel in.

Explanation

The P3057 code indicates that the fuel injector for cylinder 11 is not closing properly, causing an excessive amount of fuel to enter the combustion chamber.

Technical description

Fuel injectors are responsible for delivering the correct amount of fuel to the engine's cylinders. When an injector is stuck open, it continuously allows fuel to flow, leading to a rich air/fuel mixture. This can cause poor engine performance, increased emissions, and potential engine damage if not addressed.

Symptoms

• Poor engine performance

• Increased fuel consumption

• Check Engine Light illuminated

Common Causes

• Faulty fuel injector

• Electrical issue in the injector circuit

• Contaminated fuel causing injector to stick

Glossary
