Honda Check Engine Light Common Causes
Has your Honda Accord, Civic, or CR-V’s check engine light come on? When you notice an engine warning light on your dashboard for the first time, it might be unsettling. The “check engine” warning light may be activated by a broad variety of problems, some of which are more significant than others.
Thankfully, Engine Finder is available to assist you in determining what could be wrong and what to do next. We have included a list below that details the most typical reasons why a check engine light may come on.
Your petrol cap is either missing, damaged, or has become loose.
Problems with the petrol cap may lower fuel pressure and let fuel vapors escape, which will decrease fuel efficiency and increase dangerous emissions.
Failing Catalytic Converter
Over time, particularly with higher mileage cars, your catalytic converter may get clogged with debris. The catalytic converter, which eliminates harmful carbon monoxide, is an essential component of the emissions system. Fuel efficiency and vehicle performance may be significantly affected by a faulty or blocked catalytic converter.
Defective Spark Plugs and/or Spark Plug Wires
You will inevitably find that you need to replace either your spark plugs or your spark plug wires. Your engine is able to start and continue to operate because it has spark plugs that generate a hot spark that burns the air-and-fuel combination that is contained inside the cylinder. Your engine may misfire, resulting in decreased fuel efficiency, performance, or even total failure. Defective spark plugs and spark plug wires might even prohibit your engine from starting.
Faulty Oxygen Sensor
Your oxygen sensor may need to be replaced since it has been exposed to hot exhaust gas for a long time. The oxygen sensor gives the ECU crucial information about the air-fuel combination. Your car’s computer may over- or under-fuel the engine as a result of a damaged oxygen sensor. An engine that has too much gasoline will produce a lot of smoke and stench, while one that has too little fuel would likely completely fail.
Faulty Mass Air Flow Sensor
The Mass Air Flow (MAF) sensor may malfunction when exposed to soiled or particle-rich air. Like oxygen sensors, MAF sensors analyze engine air to maintain correct air-fuel combination. Your engine may misfire as a result of a bad MAF sensor, which will eventually result in poor fuel efficiency, poor performance, and maybe further needless engine damage.
