PART AND SYSTEM NAME LIST
This reference list indicates the part names used in this article along with their definitions.
PART AND SYSTEM REFERENCE TABLE
malfunctions per driving cycle. "Once per driving
cycle" means that the ECM detects malfunction
only one time during a single driving cycle.
"Continuous" means that the ECM detects
malfunction every time when enabling condition is
met.
DurationThe minimum time that the ECM must sense a
continuous deviation in the monitored value(s)
before setting a DTC. This timing begins after the
"typical enabling conditions" are met.
Malfunction thresholdsBeyond this value, the ECM will conclude that
there is a malfunction and set a DTC.
MIL operationMIL illumination timing after a defect is detected.
"Immediately" means that the ECM illuminates
MIL the instant the ECM determines that there is a
malfunction. "2 driving cycle" means that the ECM
illuminates MIL if the same malfunction is detected
again in the 2nd driving cycle.
Component operating rangeNormal operation range of sensors and solenoids
under normal driving conditions. Use these ranges
as a reference. They cannot be used to judge if a
sensor or solenoid is defective or not.
