Symptom List:
P0133-O2 SENSOR 1/1 SLOW RESPONSE
P0139-O2 SENSOR 1/2 SLOW RESPONSE
P0153-O2 SENSOR 2/1 SLOW RESPONSE
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: With ECT greater than 147°F, after reaching a vehicle speed of 10 mph,
and the throttle remaining open (off idle) for 2 minutes, bring the vehicle to a stop and
allow the engine to idle with the transmission in DRIVE.
Set Condition: The oxygen sensor signal voltage is switching from below 0.27 of a volt to
above 0.62 of a volt and back fewer times than required.
P0139-O2 SENSOR 1/2 SLOW RESPONSE
When Monitored: Start engine. Allow engine to idle. For 1st part of test, if limits are
exceeded, test passes. If not, 2nd part of test runs. amb/batt temp >44°F, Baro >22.13
H2O, battery >10.5 volts, MAP >11.79 & <18.15 H2O, RPM >1350 & <2200 and vss >50
and <65.
Set Condition: The oxygen sensor signal voltage is switching from below 0.39 of a volt to
above 0.58 of a volt and back fewer times than required.
P0153-O2 SENSOR 2/1 SLOW RESPONSE
When Monitored: With ECT greater than 147°F, after reaching a vehicle speed of 10 mph,
and the throttle remaining open (off idle) for 2 minutes, bring the vehicle to a stop and
allow the engine to idle with the transmission in DRIVE.
Set Condition: The oxygen sensor signal voltage is switching from below 0.27 of a volt to
above 0.62 of a volt and back fewer times than required.
P0159-O2 SENSOR 2/2 SLOW RESPONSE
When Monitored: Start engine. Allow engine to idle. For 1st part of test, if limits are
exceeded, test passes. If not, 2nd part of test runs. amb/batt temp >44°F, Baro >22.13
H2O, battery >10.5 volts, MAP >11.79 & <18.15 H2O, RPM >1350 & <2200 and vss >50
and <65.
Set Condition: The oxygen sensor signal voltage is switching from below 0.39 of a volt to
above 0.58 of a volt and back fewer times than required.
