    • Thanks for providing your vehicle information. On a 2016 Chevrolet Colorado, the P268F code Cylinder 4 Injector Data Incompatible usually points to a problem with the injector itself, the injector calibration data, or the engine control module (ECM).

      Each injector has unique calibration data that must be programmed into the ECM. If an injector was replaced and the new calibration wasn't updated in the computer, or if there’s a software issue or wiring problem, it can trigger this code.

      Here are a few common causes to check:

      • The injector for cylinder 4 may be faulty or incorrectly installed.
      • The wiring harness to cylinder 4’s injector might be damaged, loose, or corroded.
      • The calibration code for the injector might not have been programmed into the ECM correctly.
      • There could be a software update available for the ECM that addresses injector data issues.

      If the truck is running rough, misfiring, or you recently had injector work done, it’s a good idea to double-check the injector installation and programming. Otherwise, a proper diagnosis with a scan tool that can read injector calibration info will be needed.

      Hope this helps point you in the right direction!
