currents that more or less than
set values (less than 0.2 A or
more than 2 A)
When recognition the heating
voltages than less than set
values (less than 2 v)
Maintenance Hint
•
Monitoring the actual output signal
through scan tool
•
Inspection the ECM pin 16, 17 about
short circuit or open with bad contact
•
Inspection the oxygen sensor
•
Inspection the ECM
•
Monitoring the heating status through
scan tool
•
Inspection the ECM pin 9 about short
circuit or open with bad contact
•
Inspection the heating power source
•
Inspection the heating circuit of oxygen
sensor
•
Inspection the ECM
