Symptom List: P0133-1/1 O2 SENSOR SLOW RESPONSE Test Note: All symptoms listed above are diagnosed using the same tests. The title for the tests will be P0133-1/1 O2 SENSOR SLOW When Monitored and Set Condition: P0133-1/1 O2 SENSOR 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 Set Condition: The oxygen sensor signal voltage is switching from below 0.27 volts to above 0.62 volts and back fewer times than required. P0139-1/2 O2 SENSOR 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 9 H2O, battery >10.5 volts, MAP >11.79 & <18.15 9 H2O, RPM >1350 & <2200 and vss >50 and <65. Set Condition: The oxygen sensor signal voltage is switching from below 0.39 volts to above 0.58 volts and back fewer times than required. P0153-2/1 O2 SENSOR 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 Set Condition: The oxygen sensor signal voltage is switching from below 0.27 volts to above 0.62 volts and back fewer times than required. P0159-2/2 O2 SENSOR SLOW RESPONSE When Monitored: Start engine. Allow engine to idle. For 1st part of test, if limits are exceeded, test passes.
