Oxygen Sensor Heater Resistance
Connections: W lead [C] ←→ W lead [D]
Standard: 6.7 
10.5 Ω at 20° (68°F)
If the reading is out of the standard, replace the sensor.
If the reading is within the standard, check the power source voltage (see Oxygen Sensor Heater Power Source Voltage Inspection).

Armature Inspection
Using the × 1 Ω hand tester range, measure the resistance
between any two commutator segments [A].
Special Tool - Hand Tester: 57001-1394
If there is a high resistance or no reading (∞) between any
two segments, a winding is open and the starter motor
must be replaced.
