There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.


Can a check engine light indicate a bad thermostat?

Many vehicles will trigger a check engine code if the engine never reaches its designated operating temperature (Such as if a thermostat was stuck open). However, there are hundreds of other reasons a check engine light can come on. Putting in a thermostat solely because the check engine light came on is a very bad idea. Any time that light comes on you should have the vehicle scanned by a trained proffessional (The guy at Napa doesn't count). A good service technician can use the information given by the engine computer to determine what is wrong with the vehicle.

What is wrong when check Eng light is on and mechanics scanner lists rear wiper and also undocumented code wiper works fine on 1999 Grand Caravan?

This is ridiculous. Find a new mechanic and have the computer scanned again. The rear wiper has nothing to do with the Check Engine light and would never come up on a scanner code. The Check Engine light comes on when their is a problem with the emissions system.

Could a flashing cruise control light set off the check engine light or do you have two issues?

Hmmm, never heard of a flashing cruise control light. To answer your question: well, sort of. Could be the same problem causing both symptoms. Auto Zone and other auto parts stores will read your check engine code and let you know what the code means. They don't usually charge anything for this service. According to a dealer, whenever the check engine light comes on it inactivates the cruise control, resulting in both the check engine light being on and the cruise light flashing. Although this is possible, I had a '96 Outback with a nearly constant check engine light that I threw literally thousands of dollars at and never fixed and my current 2000 Forester that lost the head gasket causing a check engine light with several faults and my cruise always worked. Guess it depends on the fault. Go get it checked out. Cheap to find out just what the trouble code is. --Ken

How can I turn off my engine light. It is constantly on. Never shuts off. I have a 2002 kia sportage.?

check the codes to determine why it is lighting up. Then fix the problem, reset the code and the light should go off. A "check engine" light comes on when the computer has detected a "fault". That's typically caused by a problem with one or more sensors. Use a code scanner to read the fault code, fix the problem and the light will go out.


Can you run a 1998 Dodge Durango without a thermostat?

Only in an emergency. The computer will turn on the check engine light if the temp never reaches normal. A cold running engine is also more prone to oil sludge problems.Only in an emergency.
