Computer Relearn Procedures -> Saturn -> Auto Learn Method -> Crankshaft Learn Procedure -> Crankshaft Relearn Procedure -> Passlock Theft Deterrent Relearn Procedure -> PCM/ECM Learning Procedure -> Remote Keyless Entry Synchronization -> Seed & Key Method
Vehicle: 1994 Saturn SL Series 1.9 L4 GAS
Crankshaft Learn Procedure
The PCM uses crankshaft velocity calculations to determine engine misfire and to run misfire self-diagnostics. The PCM must know precisely the variability in crankshaft notches for this function. The PCM has a notch learn process that learns the variability between notches which must be reset if the crankshaft has been replaced. Using a suitable scan tool, the "Crankshaft Learn Procedure" can be set to "Relearn."
Crankshaft Relearn Procedure
Any time a PCM or crankshaft position sensor is replaced the PCM must relearn the crankshaft notches. ...
