Code P050B Lincoln Description

The cold start ignition timing performance has a functional response test of actual spark timing angle actual versus commanded spark timing in the Powertrain Control Module (PCM). The monitor compares commanded spark timing to the spark timing desired by the PCM. When the difference between desired and commanded spark timing exceeds the calibrated threshold, the DTC sets.
