What does this mean?OBD Code
P0371 refers to the optical sensor which
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.
