5 Commonest Check Engine Light Issues

 

For any diligent car owner, a check engine light could be extremely intimidating. However, it is most likely that it could be a minor issue which could be resolved by a free check engine light diagnosis from your end. 

According to a centre conducting engine diagnostic service in California, once a check engine light illuminates on your dashboard, the possibilities are that one of the following five things may have occurred, which are the commonest causes of the fateful check engine light (CEL).

1. Petrol Cap Becomes Loose- This is possibly the most convenient check engine light to fix. If you forget to put your fuel filler cap back on, it can certainly precipitate a CEL, as the vehicle identifies the inaccurate pressure within the tank.

2. Issues With Spark Plug or Coil- According to a team performing smog service in Rancho Cucamonga, spark plugs may also trigger a check engine light. Defective spark plugs can lead to misfires or even cylinders to stop running completely. The coil packs situated on top of the plugs may produce the same symptoms when it malfunctions.

3. Flawed Oxygen Sensor- A leading check engine light diagnostics in California claims that this is apparently the commonest cause of all. The function of an oxygen sensor or 02 sensor is to estimate levels of oxygen in the exhaust and providing a piece of proper information to the ECU as feedback. The ECU will then fiddle with the fuel/air mixture as required.

If the sensor isn’t functioning, expect your car to squander more of your money by burning more fuel. Accordingly, this will pose serious threats to the other components like the spark plugs.

4. Catalytic Converter Issues- The honeycomb formation seen within a catalytic converter, captures all sorts of nasty pollutants and evades them from being spat out of the tailpipe. What if it becomes clogged or even crumble over time? If there is any serious challenge posed by the catalyst converter, you can observe an adversely affected performance and a sulphur smell originating from the exhaust.

5. Mass Airflow Sensor Damage- While explaining the faulty oxygen sensor, we mentioned about the fuel/air mixture earlier. The MAF or mass airflow sensor plays an important role in this procedure, assessing how much air is going into the engine. If there’s any challenge regarding it, your engine may start running more roughly than before and there’ll be a check engine light lit up on your dashboard.

It is crucial that you find the cause of a check engine light as early as possible. Else there are professionals in abundance from whom you can get expert consultations about the same.
