P2690Cylinder 5 Injector Data Incompatible

P2690 means the engine control module (ECM) has received injector data from the cylinder 5 injector that does not match the expected values stored in its memory. The ECM compares the injector's calibration or identification data against what it expects for that cylinder, and when the two do not agree, it flags the circuit as incompatible.
