NOTE: Stop the actuation before continuing.
2.O2 HEATER ELEMENT
Turn the ignition off.
Disconnect the O2 Sensor harness connector.
Measure the resistance of the O2 Heater element at the O2 Sensor
connector (component side).
On a four O2 Sensor system the resistance value for 1/1 and 2/1 O2
Heater elements is between 3.3 and 4.1 ohms and the 1/2 and 2/2 O2
Heater elements is between 4.0 and 5.0 ohms at 70° F(21.1°C).
NOTE: The resistance value will increase with warmer tempera-
tures.
Is the resistance within the listed specifications?
