malfunction indicator light on - 95 nissan altima?

Question

Hello gurus,

My car runs fine but last night the MIL turned on. My mechanic is busy for a few days and i am anxious to find out what it is. I checked the obvious and these are what i find -

1) gas cap is tightly shut
2) checked the exhaust - its clear
3) there is no loss of power at any speed
4) there is no ticking / knocking sound from the engine.
5) the radiator neck has a few drops of coolant around it - i donno if its a leak
6) the engine doesnt overheat (i.e. the temperature needle always stays at 50%)
7) i got an oil change 1 month ago.
8) the transmission is fine

If anyone could help me in guessing what it could be it ( or atleast tell me if it could be serious), it would be highly appreciated. I dont trust the other mechanics around my town and therefore hesitate to go to them.

thanks in advance!

Take your car to the workshop

Answer 2

There are many components that work together in the engine to maintain optimal engine performance and economy.
A service engine soon, or check engine light indicates that there is a sensor that is reading a condition that is "out of range".
Simply resetting the light does not solve the initial cause of the problem.
Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money.
The simplest, and most economical way to alleviate your issue, is to have the computer codes checked by a reputable shop to determine what caused the computer to signal you to begin with.

That being said, if per-chance you feel the need to reset the light in the hopes that it was a "glitch" of some kind, you could disconnect the negative battery terminal for a couple of minutes to clear the check engine light.
