Code P050B Dodge Description

Spark adjustment during a cold start is intended to provide a quick response to idle speed variations. The Powertrain Control Module (PCM) monitors spark advance on a cold start over a period, then compares the average spark advance to a threshold. The Diagnostic Trouble Code (DTC) will set when the PCM detects that engine speed is 50 RPM or more (depending on vehicle specifications) below target idle speed for more than 3 seconds, and the average spark advance is above the failure threshold for more than the specified limit. Two trip fault. Three good trips to turn off the MIL.
