P1214 BUICK Meaning
The Powertrain Control Module (PCM) monitors the crankshaft position through the Crankshaft Position Sensor (CKP). CKP information is used to determine the amount of injection timing offset required for proper operation. This code will be set if the TDC offset is greater than +2.46 degrees or less than -2.46 degrees. It seems you need to perform a TDC offset learning procedure.
