The sensor element in the oxygen sensor cannot be
tested effectively with static tests. The heater circuit
element in the sensor however, can be tested with an
ohmmeter.
MEASUREMENT
Oxygen Sensor Heater Element Resistance
15.8–18.6 Ohms
NOTICE
This test MUST be performed with the sensor at room
temperature.
First, verify if there are any stored codes for the oxygen
sensor.
NOTICE
The ECU must first run though the O2 sensor time
delay before a trouble code will be set. This may take
several minutes at idle to occur.
Short drive cycles and cold temperatures will both affect
the delay time of the O2 sensor (increases the delay).
The delay time ensures the oxygen sensor heater has
run long enough to provide accurate data.
