Q: What does code P268D mean?

Cylinder 2 Injector Data Incompatible. P268D indicates that the engine control module (ECM) has detected incompatible data from the fuel injector circuit for cylinder 2, meaning the injector's electrical or performance feedback does not match expected values. The ECM compares commanded injector operation with actual response and flags this code when the data falls outside the acceptable range, often due to a faulty injector, wiring issue, or connector problem.
