CHECK HEATED OXYGEN SENSOR
CIRCUIT RESISTANCE
• Key off.
• PCM connected to vehicle harness.
• Connect suspected heated oxygen sensor
connector.
• NGS tester connected.
• Key on, engine off.
• Access correct heated oxygen sensor PID.
• 0 2S 13 (Rear)
Note
• Heated oxygen sensor displayed as
0 2S 13 (Rear) on NGS tester.
DTC: P0142, P1143 and P1144 (H 02S
(Rear))
Test Pins: 61 and 97
•
Is voltage greater than 1.5 volts?
Yes
Go to step 9.
No
Go to next step.
7
CHECK RESISTANCE OF HEATED OXYGEN
SENSOR GROUND CIRCUIT IN THE PCM
• Key off.
• PCM connected to breakout box. Vehicle
harness disconnected from breakout box.
• Measure resistance between Test Pin 91
and Test Pin 24 and 103 at breakout box.
• Is resistance reading less than 5.0
ohms?
Yes
REMOVE breakout box.
RECONNECT PCM.
Go to next step.
No
REPLACE PCM.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
8
APPLY 12 VOLTS TO SUSPECT HEATED
OXYGEN SENSOR CIRCUIT
• Key off.
• Heated oxygen sensor (Rear)
disconnected.
• Jumper power to heated oxygen sensor
signal circuit at the vehicle harness
connector.
• Key on.
• Access heated oxygen sensor PID and
monitor.
• 0 2 S 13 PID
•
Is PID voltage greater than 1.5 volts?
Yes
REPLACE heated oxygen sensor.
RECONNECT all components.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
No
RECONNECT all components.
Go to next step.
9
CHECK FOR OVER VOLTAGE ON THE
HEATED OXYGEN SENSOR CIRCUIT IN
THE PCM
• Key on.
• PCM connected to vehicle harness.
• Heated oxygen sensor disconnected.
• Inspect both ends of connect for damaged
or pushed out pins, moisture, corrosion,
loose pins, etc. and service as necessary.
• Measure the voltage between Test Pin 91
at the heated oxygen sensor vehicle
harness connector and battery negative
post.
• Measure the voltage between heated
oxygen sensor signal Test Pin at the
heated oxygen sensor vehicle harness
connector and battery negative post.
•
Are voltage readings greater than 1.5
volts?
Yes
REPLACE PCM.
RECONNECT all components.
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
No
REPLACE heated oxygen sensor.
RECONNECT all components.
RESET PCM to completely clear DTCs.
