Hi .

If the engine light came on then you have a injection system malfunction .

Let me explain what the engine light means just incase you are not sure what to do
then get back to me if needed.

The check engine light is yellow, meaning you don't have a great problem, this comes on when the management system (ECM), encounters a malfunction within the engine and transmission system.

Unless you have noticed the engine is misfiring,which means this should be checked asap due to the fact a misfiring engine will damage the catalytic converter's.

Now if the engine is running well ,then you don't have to get to the garage asap but when you have the time.

What i suggest you do is find a good local garage that has a diagnostic scan tool (shops computer engine tester).

Once the scan tool is connected it will be able to read a stored code or codes
(A code will be stored due to a malfunction of a part or sensor, it will turn the light ON)

The found code or codes will let you know what has malfunctioned and the testing technician will then let you know what has to be done to repair this issue .

Once the repair has been done the the codes will have to be cleared, which will switch off the check engine light, if the repair has been done correctly then the check engine light should stay off.
