10 Possible Car Repairs To Be Done If Your Check Engine Light Is On

Most of the time you simply assume your car can still hold up, so you skip on few of the car maintenance. But once you see your check engine light is on, you shouldn’t delay anymore. Here are the possible reasons why it may be on.

1. Oxygen Sensor Replacement
O2 sensors can fail prematurely for a variety of reasons like engine contamination from internal coolant leaks or ignoring oil changes.  When this happens your check engine light will surely go off.

2. Catalytic Converter Replacement
This is rarely the reason that would trigger your check engine light. But it does happen when you ignore a faulty spark plug, ignition coil, or engine mechanical problem.

3. Ignition Coil(S) And Spark Plug(S) Replacement
This ranked as the third most common check engine light repair in 2015. Always check and replace them when necessary to avoid more serious issues.

4. Tighten Or Replace Fuel Cap
Although this is a cheap fix, do not underestimate it. Make sure you take your vehicle to car servicing in case of missing or damaged fuel caps. Otherwise it could cause reduced fuel economy and harm the environment.

5. Replace Thermostat
The thermostat is responsible for regulating the engine coolant temperature to warm and cool to ideal “operating temperature.” When it fails it illuminates your check engine light. Make sure you get it replaced at recommended mileage intervals.  

6. Ignition Coil(S) Replacement
Faulty spark plugs, high engine bay temperature and age are some of the reason your ignition coils may fail. This then turns your check engine light. When this happens pay special attention before it causes damaged catalytic converter.

7. Change Mass Air Flow Sensor
When the mass air flow sensor is malfunctioning, fuel economy can drop anywhere from 10 percent to 25 percent. Definitely not good, change your mass air flow sensor right away.

8. Change Spark Plug Wire(S) And Spark Plug(S)
In areas with cold weather, fuel doesn’t vaporize as easily, so droplets can form and foul a spark plug. Good thing this is relatively cheap if you do it yourself.

9. Evaporative Emissions (EVAP) Purge Control Valve Replacement

If the purge flow is monitored as more or less than expected by the engine’s computer, the check engine light will come on. The purge valves can also get stuck, causing a need to be replaced. 

10. Replace Evaporative Emissions (Evap) Purge Solenoid
This particular repair can be a bit pricey, but once the need for it to be replaced arises you should take it to the car servicing at once. The purge solenoid is controlled by the engine control module or power train control module and operates on a duty cycle and could be partially left open.
