P0723 1999 Ford F150 Code - Output Shaft Speed Sensor Circuit Intermittent Failure
Quick Answer
The Output Shaft Speed (OSS) Sensor provides the Powertrain Control Module (PCM) with information about the rotational speed of an output shaft. Common causes include Faulty Output Speed Sensor (OSS), Output Speed Sensor harness is open or shorted, Output Speed Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
