Code P2696 Description

The P2696 diagnostic trouble code (DTC) refers to "Injector Data Incompatible." This code indicates that there is a discrepancy between the data being received by the engine control module (ECM) from the fuel injectors. Fuel injectors are responsible for delivering the precise amount of fuel into the engine cylinders for combustion. When the ECM detects that the injector data is incompatible, it means that the expected fuel delivery is not matching the actual fuel delivery, which can lead to a range of performance issues.
