ISSUE:
The Malfunction Indicator Lamp (MIL) may illuminate and set Diagnostic Trouble Code(s) (DTC) P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, or P0308 on some vehicles. This may be due to the pulse ring of the crankshaft pulley and damper assembly being removed, replaced or reinstalled. This causes an incompatibility with the profile correction, or "learning", data stored within the Powertrain Control Module (PCM), which will illuminate the MIL when the engine is started

ACTION:
Remove the negative battery cable for at least 5 minutes to erase the original profile correction memory when removing, replacing, or reinstalling a pulse ring.
