What does this mean?

OBD Code P0380refers to

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. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.

Symptoms

Possible sumptoms of OBD code P0380

- Engine Light ON (or Service Engine Soon Warning Light)

Causes

Possible causes of OBD code P0380

- Open or short in the optical sensor circuit - Optical sensor connector - Damaged optical sensor - Damaged PCM or ECM The Error code is generally activated on detection of the following conditions: Some high resolution pulses are missing from the optical sensor to the PCM

Possible Solutions

- If damage, repair optical sensor circuit - Replaced optical sensor - Replaced PCM or ECM""



hi all, anyone know what the above translates into?
