P1900 FORD, MERCURY, LINCOLN: OUTPUT SHAFT SPEED (OSS) SENSOR - CIRCUIT INTERMITTENT
The Output Shaft Speed Sensor (OSS) provides the PCM (Powertrain Control Module) with relevant data on the rotational speed of an output shaft. This module uses this information for the control and diagnosis of powertrain behavior. On some vehicle models, this sensor is also used as a speed source. The location of the OSS sensor varies from manufacturer to manufacturer. Its design is unique and depends on the powertrain control features used to generate the data.
The P1900 OBD2 fault code on Mercury, Ford, and Lincoln vehicles is set when the PCM detects that the signal received from the Output Shaft Speed Sensor is erratic or has been interrupted.
