Ram 1500 engine light on, gas cap replacement did not resolve issue on Ram 1500

Some Ram 1500 owners report experiencing persistent check engine light issues even after replacing the gas cap. These problems can occur if the new gas cap is not securely tightened, as a loose cap can still trigger the light. Additionally, faulty sensors, such as the crankshaft position sensor, camshaft position sensor, and throttle position sensor, may malfunction and keep the check engine light illuminated. Furthermore, issues with the purge valve, which controls fuel vapors, can also contribute to this ongoing concern. If replacing the gas cap does not resolve the issue, it is advisable for owners to investigate these other potential causes to effectively address the problem.
