Can the GS4 still be driven if the emission system fails?

[MacMaverick]

Generally, if it's not a complete failure, the car can still run for a certain distance. However, if it's a complete failure, such as a blocked exhaust pipe, you should stop driving immediately and have it repaired. The engine trouble code needs to be checked with a computer. Based on the trouble code, the cause can be identified. When the engine is not working properly, the exhaust emissions will exceed the standard, and the oxygen sensor will detect abnormal fuel mixture and report a fault code for the emission system. The impacts include: 1. Affecting fuel consumption: Over the long term, poor combustion can lead to excessive carbon buildup, but there is no direct adverse effect on the engine in the short term. 2. Affecting safety: An emission system failure can affect the safety of the car while driving and reduce the engine's service life. 3. Other impacts: Due to fuel or lubricant issues, the catalytic converter may become poisoned or lose activity, affecting catalytic conversion efficiency. Sulfur and phosphorus compounds and deposits may form inside the three-way catalytic converter, leading to degraded car performance, reduced power, increased fuel consumption, and worsened emissions.
