7 ELECTRONIC CONTROL SYSTEMS DIAGNOSTICS
DTC 332
ICP above specification with engine not running
•
DTC 332 is set by the ECM, if the voltage signal
from the ICP sensor is greater than expected with
the key-on engine-off. If the ECM sets DTC 332,
the ECM will ignore the ICP signal and operate the
IPR with fixed values based on engine operating
conditions.
•
DTC 332 can be caused by an open signal
ground, V
shorted to voltage source greater
REF
than 5.5 V, a biased circuit, a failed ICP sensor,
or a momentary loss of either the CMP or CKP
signal.
•
When DTC 332 is active the amber ENGINE lamp
is illuminated.
