Circuit Description

WARNING: This page is about a different variant/trim than selected.

PCM uses a calibrated resistor mounted internally in injection pump to determine fuel rates. Resistor value is stored in PCM memory. If PCM memory is disturbed or PCM is replaced, PCM will relearn resistor value on next ignition cycle.

DTC will set when the following conditions are present:

PCM currently does not have a valid resistor value.
PCM is unable to read resistor value.
