P0373 MINI Code - Timing Reference High Resolution Signal 'A' Intermittent/Erratic Pulses
Quick Answer
The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. Common causes include Timing Reference Optical Sensor harness is open or shorted, Timing Reference Optical Sensor circuit poor electrical connection, Faulty Timing Reference Optical Sensor. 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.
