Trouble Area
When recognition the output
that more than nominal
threshold, malfunction of
sensing voltage.
When recognition the output
that more than nominal
threshold, malfunction of
sensing voltage.
When recognition the output
that not active the sensor etc.
When recognition the output
that no lean signal after
overrun fuel shut-off
When slow response of sensor
signal
When recognition the heating
circuit
When recognition the heating
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 2v)
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
