In a Chevy Silverado, if you get the P0200 trouble code, it means the engine control module (ECM) found an issue in the fuel injector system. This system controls how much fuel is sprayed by the injectors to make the engine run. When the ECM notices that the sensor is not working right, it triggers the code, which might be due to voltage or resistance problems in the circuit. The ECM will then activate a protective "failsafe" mode to prevent damage. Potential causes of this issue include a faulty fuel injector, a wiring harness short, or a problematic ECM. To likely resolve this, you should consider replacing the fuel injectors and inspecting the wiring harness for any faults.
The code P0200 appearing on a Chevy Silverado indicates an issue within the fuel injector circuit.
