Begin with the lowest code number first.

The dash indicator circuit is not controlled by the cruise control module.

Basic checks- make sure diaphragm of control is not ruptured- it might be if you have had a difficult to locate "lean" engine fault code. You can manually apply vacuum to the diaghram to make sure it is not binding.

There is an electrical interlock with the brake pedal- it interupts power to module when brakes are applied. This is located near the pivot. There is also a vacuum dump valve actualted by the brake pedal as well.

If the tilt feature of the steering column is used often, there is a chance wires may have broken over time, or abraided and are shorting out. The steering wheel buttons all have a circular track they contact underneath the steering wheel itself- a brush may have broken, worn away, or accumulated conductive dust from the other brushes.

There is also a magnetic speed sensor which should be located on the same billet transmission insert that the speedometer gear is mounted in- the magnet may have fallen off, lost flux or the hall effect sensor portion failed.- it tests much like a transistor, but the bias to allow current to flow through it is by way of magnetic field.

I had a similar problem on a similar Pontiac, with a broken wire going to the temperature sensor connector. The temp. sensor will keep it from running, if the computer does not see it. If the check engine light is on when its runs, then you have a fault. Get a code reader and get the code Otherwise it could be the temp. sensor, a broken wire for the temp. sensor or a dirty bulkhead connector at the firewall.

Do you have a service engine light on or does the smog station tell you that the monitors are set?
A drive cycle won't clear a service engine light if the reason for it was not fixed. Normally a drive cycle or a 25 or so mile drive will be enough for the PCM to run through its test, and if all is well, clear the monitors.
Now some shop scanners and code readers can clear the monitors. Actron is one of the code readers that I know of that will clear monitors (the newer models. older ones did not). They are about $75 for the basic code reader and may be a worthwhile investment for the do it yourselfer.
Auto Zones also have code readers and if theirs is capable may do it for you. Though if you're in California I have heard they don't do that any longer due to people getting codes cleared just before a smog test without fixing the issue first.

You need to find out the error codes being generated when the light came on. These codes will stay in memory until being reset by a code reader. The reader plugs into the OBD II port under the dash, near the steering wheel. (OBD stands for On Board Diagnostics). You can buy or rent these readers for not to much money now a days. Costco has a basic one for about $40. http://www.kiatechinfo.com/index.asp This is Kia's tech website. You, or anybody else, can register there and get loads of information about your car, including what the error codes mean, for free. Good luck!

Check engine light


This could be anything from a bad sensor, to a bad ECM.

The cars computer turns that light on when it detects something isn't right. Your car is always running a diagnostics on itself to ensure nothing is wrong. You can either take the car to a shop and they'll put it on a computer to diagnose what the engine code is. OR you can run over to you local Auto store and pick up a "Code Reader" for about 25 Dollars. It comes with a book that will tell you what the code means, the code reader (which you plug into the car) and instructions (to show you how to plug it into the car)

Other than that, I can't really help until you find out which error code the car is giving you.
