Laymans terms

The car's computer is having trouble adjusting the fuel injector for cylinder 1, and it's reached its limit trying to fix it.

Explanation

The engine control module (ECM) is unable to adjust the fuel injector on cylinder 1 beyond its maximum limit to achieve the desired fuel mixture.

Technical description

This code indicates that the ECM has detected that the offset learning for the fuel injector B on cylinder 1 has reached its maximum limit. This means the ECM is unable to adjust the injector's performance to maintain optimal engine operation. The offset learning is a process where the ECM adjusts the injector's operation to compensate for variations in fuel delivery.

Symptoms

• Check engine light is on

• Poor engine performance

• Increased fuel consumption

Common Causes

• Faulty fuel injector

• Wiring issues in the injector circuit

• Fuel delivery problems

Glossary

ECM: Engine Control Module

Fuel Injector: A component that sprays fuel into the engine's cylinders

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for cylinder 1 fuel injector.

• Test the fuel injector for proper operation.

Repair procedures

• Replace the faulty fuel injector.

• Repair any damaged wiring or connectors.

• Clean the fuel injector if clogged.

Tools required
