Morris Car owners should take immediate note when the check engine light activates, as it serves as a critical warning indicator powered by the onboard diagnostics system. This light signals that key engine data--ranging from emissions and fuel injection to ignition timing--has deviated from optimal parameters, suggesting potential issues that require prompt attention. Prioritizing a diagnostic scan to retrieve fault codes and assess sensor performance is essential for preventing larger system failures and ensuring both efficient engine operation and long-term vehicle reliability. By addressing these alerts quickly and aligning with manufacturer service recommendations, drivers can maintain peak performance and extend the lifespan of their Morris Car.
