DIAGNOSIS ITEM
Valve position control failure - DC
motor out of range, functional
(EGR actuator over temp warn-
ing level)
Controller high temperature
(EGR actuator over temp severe
level)
Controller store data error (EGR
actuator abnormal information
reading)
EGR controller power supply
open circuit (EGR actuator power
supply open circuit)
Battery voltage (high)
(EGR actuator power supply too
high)
Battery voltage (low) (EGR actu-
ator power supply too low)
EGR valve controller tempera-
ture sensor 1 (Signal too low)
(EGR actuator temp. sensor 1
signal too low)
EGR valve controller tempera-
ture sensor 1 (Signal too high)
(EGR actuator temp. sensor 1
signal too high)
EGR valve controller tempera-
ture sensor 2 (Signal too low)
(EGR actuator temp. sensor 2
signal too low)
EGR valve controller tempera-
ture sensor 2 (Signal too high)
(EGR actuator temp. sensor 2
signal too high)
EGR valve controller tempera-
ture sensor 1, 2 - rationality
(EGR actuator temp. sensor 1
performance invalid)
