What Causes the Engine Light to Illuminate in a Newly Purchased Car?
1 Answers
Newly purchased car engine light illumination is caused by: unclean fuel leading to contamination or blockage of the fuel supply system. Currently, some vehicles are equipped with exhaust emission monitoring systems. As these control systems can very sensitively detect vehicle exhaust emissions and fuel cleanliness conditions, the use of unclean fuel can cause contamination in the fuel supply, ignition, and emission systems, leading to the engine malfunction indicator light illuminating and varying degrees of engine vibration. An effective solution is: after thoroughly cleaning the contaminated system, consistently add gasoline with stable performance indicators and a quantitative amount of fuel system cleaner, and the situation will improve.
