I don't know what kind of Saturn you have but it probably is in the right kick panel by the pass right foot. The PCM is located inside the passenger compartment under the dashboard tucked into the corner near the ABS module on the driver's side. The PCM is easily distinguished by the aluminum fins attached to the bottom of the module. BUT on a 1992 Saturn it is on the DRIVERS side. Look up under the dash to door side. You'll see it. 3 wire harnesses attached. ONE phillips-head-type bolt holds in it. About a half a twist on it and tug a little and it should drop right down. cheers If your Saturn is an S-Series (SC, SC1, SC2, SL, SL2, SL2, SW1 or SW2), its not on the passenger side. No Saturn S-Series had them on the passenger side. If its a 1991-1999, its just as described above. If its a 2000-2002, its just behind the battery. And a little FYI, the Saturn PCM's rarely fail. You have a better chance of getting struck by lightning in a cave 1000 feet under ground than having your PCM fail.

How do you reset 1999 Saturn pcm?
To reset the PCM (Powertrain Control Module) on a 1999 Saturn, disconnect the negative battery cable and leave it disconnected for about 15 minutes. This allows the PCM to clear any stored trouble codes and resets its adaptive memory. After that, reconnect the battery cable, and your PCM will be reset. It's also a good idea to drive the vehicle for a while to allow the PCM to relearn its parameters.

Is a 1995 Saturn PCM Computer compatible with a 1994 Saturn SL1?
I just did the engine in my 94 and wanted to do a 96 engine. The only computers that will be compatible in a 94 is a 91 0r 92.95 PCM Computer in a 94 Saturn S SeriesNo it is not compatible. The amount of teeth on the 94's timing wheel do not match what the PCM Computer is programmed for in the 95. It will run the engine, but it will always run lean and you will have a drastic reduction in horse power.
