i10 illuminated1.2 engine 3 years old ca 30000miles. Malfunction

i10 illuminated1.2 engine 3 years old ca 30000miles. Malfunction light on. What gives?

let me explain the function of the check engine light.


When driving your car and suddenly you notice that the check engine light is "ON", then this means the management system (ECM) has encountered a malfunction within the emission system .

In some cases you will not notice any difference in the driving quality.
Or you may notice the engine power has dropped or its starting to misfire ...

If the light is flashing then this will be a misfire code and i would suggest you get this checked and repaired asap, as a misfiring engine will cause catalytic converter damage.

Now if you don't notice any difference in the driving quality, then you are okay to keep on driving until you have time to get to a shop.

Ones at the shop they will hook up a diagnostic scan tool(OBDII) to check for malfunction codes .

Once you have the codes then you will know what has malfunctioned and what has to be done to rectify this problem..

Check engine light "ON" means you could have any of 100reds of problems..

For example the MAP sensor is 1 of many that will trip off the check engine light.

The Yellow wire could be your issue. check and see if you can find the other connector to this wire , if you find the wire then connect and disconnect the battery ,this will clear the malfunction codes and switch of the check engine light .if this was the problem then the light will stay OFF of not then you will need to be hooked up and the system checked for codes,

Need further assistance then please get back to me with the reply box and not the poor or bad service button .
