CHECK HEATED OXYGEN SENSOR
HARNESS CIRCUIT FOR SHORT TO
POWER AND GROUND AND PCM GROUND
(BETWEEN PCM AND H 02S GROUND
CIRCUIT)
• Key off.
• Disconnect NGS tester from data link
connector.
• Disconnect PCM. Inspect both ends of
connector for damaged or pushed out pins,
moisture, corrosion and loose pins. Service
as necessary.
• Breakout box installed. Leave PCM
disconnected.
• Disconnect suspected heated oxygen
sensor.
• Measure resistance between heated
oxygen sensor signal Test Pin and PCM
ground Test Pin at breakout box.
• Measure resistance between heated
oxygen sensor signal Test Pin and power
and constant voltage Test Pin at breakout
box.
• Measure resistance between heated
oxygen sensor signal Test Pin and ground
Test Pin at breakout box.
• Heated oxygen sensor (Middle)=Test
Pin 35
• PCM ground=Test Pin 91
• Ground=Test Pins 24 and 103
• Power=Test Pin 71 and 97
• Constant voltage=Test Pin 90
•
Is resistance greater than 10,000 ohms?
Yes
Go to next step.
No
SERVICE short circuit in harness.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
c r After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.

CHECK RESISTANCE OF HEATED OXYGEN
SENSOR AND HEATED OXYGEN SENSOR
GROUND CIRCUIT
• Key off.
• Breakout box installed, PCM disconnected.
• Disconnect suspected heated oxygen
sensor.
• Measure resistance between heated
oxygen sensor signal Test Pin at breakout
box and heated oxygen sensor vehicle
harness connector. Record readings.
• Measure resistance between PCM ground
Test Pin at breakout box and heated
oxygen sensor PCM ground vehicle
harness connector. Record readings.
• Heated oxygen sensor (Middle)=Test
Pin 35
• PCM ground=Test Pin 91
•
Is resistance reading less than 5.0
ohms?
Yes
Go to next step.
No
SERVICE open circuit in harness.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
c r After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
