Hi

Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.

If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.

Very best regards

SOURCE: 2002 kia optima wont pass

Reseting the cpu will clear the check engine code however it will not fix the problem that caused the check engine light to come on. The most common cause of failing emissions is the O2 Sensor. This sensor will trigger the check engine light when it is failing. The good news is that the Oxygen senser is pretty cheap and is mounted on your exhuast so it is fairly easy to replace yourself. I suggest replacing your O2 sensor the clear the computer by disconnecting the negative battery terminal and leave it disconnected for a few moments, hook up the negative again and it's all clear. Take your car back threw emmisions and you should be all set.

Hope this helps

SOURCE: 2004 KIA Optima LX timing belt/water pump

The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.

Car dies when driving,check engine light comes on.


There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.
