Can You Still Drive When the Exhaust Malfunction Light Is On?
1 Answers
When the exhaust malfunction light is on, you can still continue driving. Not all exhaust malfunction lights indicate that the vehicle cannot be driven. If the engine malfunction light is on, there are no abnormal noises in the engine compartment, no other abnormal warnings on the dashboard, the vehicle's power is unaffected, and the transmission shifts normally, you can continue driving to a 4S shop for further diagnosis. Issues such as intake or exhaust problems may trigger the engine malfunction light. Introduction: This commonly referred to exhaust malfunction light is also known as the fuel injection system malfunction light. As long as there are no unusual changes in engine power or sound, you can continue driving. This is because the ECU (Engine Control Unit) has a fault substitution program. If any sensor among the many sensors fails, the ECU will use pre-set backup parameters to replace the faulty sensor's data to prevent the vehicle from stalling. For example, if the coolant temperature sensor fails, the ECU will use a backup value of 80 degrees Celsius as the control parameter for fuel injection and ignition. Therefore, while driving is possible, timely repairs are still necessary. If not addressed promptly, the following issues may arise: Deterioration in exhaust gas quality, leading to environmental pollution; increased fuel consumption; elevated combustion chamber temperature and accelerated wear, causing faster engine deterioration; increased engine noise, affecting driving and passenger comfort.
