Corrective Action
 Check the ECM leads.
 Check for sensor shorts for
sensors using 5 V sensor power
supply by disconnecting all
sensors and then connecting
back one at a time.
 Isolate a defective sensor. While
monitoring the sensor power
supply with a scan tool or
voltmeter, disconnect all sensors
powered from the sensor
reference voltage C power
supply. When the defective
sensor is plugged back in, the
voltage will fall.
 Replace the ECM. Refer to
Section 5.4.
 Check for exhaust leaks before or
near the HEGO sensor.
 Check for intake manifold leaks.
 Verify that the HEGO sensor is
installed securely.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
 Check for exhaust leaks before or
near the HEGO sensor.
 Check for intake manifold leaks.
 Verify that the HEGO sensor is
installed securely.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
to Section 5.7.
 Check for excessive exhaust
temperatures.
 Troubleshoot the HEGO sensor
for bad leads. Refer to
Section 4.7.
 Replace the HEGO sensor. Refer
