Details of the Ford p02e9 OBD Code
The fault code P02E9 on a Ford indicates an issue with the fuel injector.
Ford OBD code P02E9 means that the fuel injector B supply control circuit is low.
This code is triggered by the Engine Control Module (ECM) when it detects a low voltage condition in the fuel injector B supply circuit.
This circuit is responsible for providing power to the fuel injector B, which controls the fuel delivery to the engine.
When the voltage in this circuit drops below a specified threshold, the ECM sets code P02E9 to indicate a potential issue with the fuel injector B supply circuit.
Mechanic’s Tech Notes
