Laymans terms

This code means that the car's computer has detected a problem with the fuel pump that helps deliver fuel to the engine. It's like if the pump is pushing too much fuel, which can cause the engine to not run right.

Explanation

The code indicates that the fuel injection pump is delivering more fuel than expected, which can affect engine performance.

Technical description

The P2A19 code is triggered when the Engine Control Module (ECM) detects that the fuel metering control for the injection pump is operating at a higher level than specified. This can be due to issues with the cam, rotor, or injector components, which are responsible for controlling the amount of fuel delivered to the engine.

Symptoms

• Check Engine Light is on

• Poor fuel economy

• Engine misfires or runs rough

Common Causes

• Faulty fuel injection pump

• Defective fuel injector

• Issues with the fuel pump cam or rotor
