Check engine lights are a constant hassle in any vehicle you buy. If you have checked the motor out and all the fluids are topped off, take it over to an Auto Zone and or Checker, and have them test other things such as your starter, alternator, battery. If these are all in good shape and no one can give you any idea, then it's most likely just in the wiring... sometimes the check engine light will throw even when nothing is wrong... if your car is running smoothly... no worries.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

i have a 90 chevy 2500 2wd 350ci.when i go to start my truck the key turns hard in the ignition,the check engine light and brake light come on the heater dont work,and the transmission will shift from 1-2 at real high rpm and shift hard,no 3-od.this comes and goes,but all happens at the same time.some times it last for 10 min,sometimes its days.what is going on?
Have the computer scanned if you want a quick scan have Auto Zone or the like scan it for free , they also will give you a printout of the problem code, if any, that may be stored in the computer system.
Trans. fluid is only checked on a running in park warm engine, if it is not running the fluid will read too high on the stick showing an overfilled condition, use only recommended fluid, should have the type requirements stamped on the transmision dip stick.
When filling do it slowly and add only half a quart at a time checking the level each time as to not over fill.
The trans. fluid and filter should be changed every 30,000 miles as preventive maintenance proceedures.
Hope this helps, good luck!!
probably, the check engine light could come on for so many reasons that i wouldnt have space here to list them, if it the first time its come on, then your probably ok, i have friends who continually drive with the check engine light and thier car seems just fine....
I have a 2000 Tacoma Extra Cab Pre Runner. When I put on my camper shell my check engine light comes on. Oil levels and tires are fine. I took my shell off and light goes off. I hauled alot of wood and the light did not come on. Why would the camper shell be trip-en my light? Ofcourse I am gunna get the code checked next week.
There is an ABS sensor on each wheel. Check each one and make sure they are plugged in first. If they all are plugged in, then you may need to replace one or more of them. You can usually see if they are bad. Hope this helps.
The check engine light will come on for more than just a engine problem but usually something else on the car isn't functioning properly. I had a car with a low fluid level in the transmission that would not read but the check engine light came on.
It is a warning and if it doesn't scan check the rest of the car for what isn't functioning since for sure it is connected.
50% of the time a check engine light comes on it is a loose or bad gas cap. Check that first. The oxygen sensor is next but it will read on your reader.
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you will need to have the car diagnosed and repaired. Most of the time this is not fluid level related. Take it to a service center you trust and they can tell you what the solution is.
