P1521 DODGE Description
Using the oil pressure, oil temperature and other vital engine inputs the Powertrain Control Module (PCM) can determine the engine oil viscosity. Incorrect viscosity will affect the operation of the MDS by delaying cylinder activation. The Diagnostic Trouble Code (DTC) will set when the PCM has detected an incorrect engine oil viscosity.
