P0159-O2 SENSOR 2/2 SLOW RESPONSE
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P0133-O2 SENSOR 1/1 SLOW
RESPONSE.
When Monitored and Set Condition:
P0133-O2 SENSOR 1/1 SLOW RESPONSE
When Monitored: Start and drive vehicle greater than 20 MPH and less than 55 MPH.
Throttle open for a minimum 120 seconds. Coolant Temp greater than 70°C (158°F).
Catalytic Converter Temperature greater than 600°C (1112°F)
Set Condition: The O2 sensor voltage switches less than 16 times for a 3.5L or 11 times
for 2.7L or less from rich to lean within 20 second during monitoring. Two Trip Fault.
P0139-O2 SENSOR 1/2 SLOW RESPONSE
When Monitored: Start and drive vehicle greater than 20 MPH and less than 60 MPH.
Throttle open for a minimum 120 seconds. Coolant Temp greater than 70°C (158°F). RPM
between 1200 to 2000. Vacuum between 56Kpa to 28 Kpa.
Set Condition: The O2 sensor voltage does not switch properly from lean to rich during
monitoring. Two Trip Fault.
P0153-O2 SENSOR 2/1 SLOW RESPONSE
When Monitored: Start and drive vehicle greater than 20 MPH and less than 55 MPH.
Throttle open for a minimum 120 seconds. Coolant Temp greater than 70°C (158°F)
Catalytic Converter Temperature greater than 600°C
Set Condition: The O2 sensor voltage switches only 16 times for a 3.5L or 11 times for
2.7L or less from lean to rich within 20 second during monitoring. Two Trip Fault.
P0159-O2 SENSOR 2/2 SLOW RESPONSE
When Monitored: Start and drive vehicle greater than 20 MPH and less than 55 MPH.
Throttle open for a minimum 120 seconds. Coolant Temp greater than 70°C (158°F)
Catalytic Converter Temperature greater than 600°C
Set Condition: The O2 sensor voltage switches properly from lean to rich during
monitoring. Two Trip Fault.
