Many auto parts stores like Advanced Auto/ Auto Zone etc, will read the error codes off your PCM for free. A Saturn Dealer was charging me $41, but they also check that part that the error code suggests is faulty to see if it is indeed responsible for the error code. I would suggest buying a repair manual at the same time you have your error codes read. I own a 1997 Saturn SL and I purchased a Haynes repair manual from Advanced Auto. They use an OBDII hand held scanner. If Saturn has not improved their product since I purchase mine, that SES light will be going off again and again, as one part or another either looses it't ground due to corrosion, sticks due to cabon deposits, or wears out. Let me know if this has helped.

There is a web site called Saturn Forum/ for Saturn enthusiasts. It is very helpful because it categorizes the different Saturn cars and it is all about car problems and finding resolutions to the problems. Just reading the conversations gave me the above information.

hello..
I am working on 1998 saturn s series 4dr auto w air...I just replaced the trans which had serious transaxel damage.Broken case.... pinion gears came through case ect...I thought that damage was due to abuse from young driver.However I replaced transmission(used)Previous trans I had rebuilt.I had had problems with the nut on the hub for clutch pack backing off.The donor trans worked fine for about 3-4blocks...shifted fine thru gears..then check engine light appeared...car abrubtly shifted into 1st gear and would not shift out of 1st..no slipage but no shift...took home and placed on scanner..got codes for for improper gear ratios.I cleared codes and test drove agian..with same reasuts(shifted fine at first then down shift agian...then would not shift i cleared codes agian ...same results the book for what trans will work call for 95 thru 02 I took trans from 96 The symptoms made me think that the origional damage may not of been thru young driver abuse but from pcm being faulty and car shifting to low gear all at once at a good rate of speed.I replaced the pcm from the car trans came from and trans worked fine shifting gears and all...however the car ran rough and low fuel light stayed on and gas gauge would not work.I did more research and found that only pcm from 1998 would work,which i purchased and installed.which upon testing agian made the car do the same thing agian...after this i replaced all of the selonoids ,valvebody all the sensors all electronics on the trans...trans still will not shift has anyone got a clue as to what may be the problem ????...I am goin nuts!!!!Is it possible that i got a bad pcm???

Found cause of problem.....trans 95-02 will work ...problem is that they make 2 models for each year one for single overhead cam one for double.Thats why when I used the pcm from the doner car that the trans shifted and worked but the engine ran rough because pcm was sending info for single overhead engine!Feel so stupid but learned valuable lesson for future.Also that the pcms for saturn still need to be flashed,when changing them.I thought that I would leave this info in case any one else encounters this problem....Cause it sure had me baffled.

My daughter's SC1 was over heating. After trouble shooting, I found it was a faulty temperature sending unit causing the problem. As it turns out the factory sending unit has the probe made of plastic which was cracked thus giving a false reading.

Or, you can get the free little Autozone booklet "What It Means When Your Check Engine Light Comes On" and the free "key" to insert in your diagnostic connector and do it yourself.

I am the proud owner of a 1997 4dr SL. I have replace the thermostate, radiator, water pump, and heater coil. Still, I overheat per the gauge 3 or 4 times in a 25 mile stretch. The gauge reads in the read a while and then theres some noise and it cools down. I also do not have heat. Yes, again I have change the thermostate twice. I am good on my antifreez. I am out of ideas.PLEASE HELP.

This section is for modifying your car, not repairing it, you might want to repost this in the maintenance and repair section.
