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.
Timing is controlled by the PCM .
Timing is done by the PCM. No manual timing can be done with out a new PCM
To the right of the glove box.
Idle is computer controlled by the pcm (computer)-not adjustable.
You don't - its all done by the PCM (computer). Eric
don t know thats why i am asking
PCM B fues in the underhood junction box
It is used by the PCM to determines fuel and spark timing
Refer to the link below
PCM, Relays, Power locks, wiring
The PCM is inside the dashboard, to the right of the glove box.
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.
