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 100 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 a calibrated value.

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 a calibrated value.

P013E or P014A 

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

P013F or P014B 

The ECM detects that the O2 sensor voltage has not increased above 350 mV within a calibrated value 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 100 s when the above condition is met.
