Conditions for Setting the DTC



P0133 or P0153



* The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is greater than a calibrated value.



* The DTCs set within 60 s when the above condition is met.



P013A or P013C



The ECM detects that the accumulated mass air flow monitored during rich-to-lean transitions between 450-150 mV is greater than 75 grams.



P013B or P013D



The ECM detects that the accumulated mass air flow monitored during lean-to-rich transitions between 350-650 mV is greater than 75 grams.



P013E or P014A



The ECM detects that the O2 sensor voltage has not decreased below 450 mV within 42 grams of accumulated air flow.



P013F or P014B



The ECM detects that the O2 sensor voltage has not increased above 350 mV within 200 grams of accumulated air flow.



P1133 or P1153



* The ECM detects that the HO2S 1 rich-to-lean counts, or the lean-to-rich counts are less than a calibrated value.



* The DTCs set within 60 s when the above condition is met.



Action Taken When the DTC Sets



DTCs P0133, P013A, P013B, P013C, P013D, P013E, P013F, P014A, P014B, P0153, P1133, and P1153 are Type B DTCs.



Conditions for Clearing the DTC



DTCs P0133, P013A, P013B, P013C, P013D, P013E, P013F, P014A, P014B, P0153, P1133, and P1153 are Type B DTCs.

Circuit/System Verification



1. Ignition ON, observe the DTC information with a scan tool. Verify no B52 HO2S heater DTCs are set.



瀚慖f a B52 HO2S heater DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code



Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).



2. Engine running, observe the appropriate scan tool B52 HO2S voltage parameter. The reading should be within the range of 50-1,050 mV.



3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
