not set.
* The ignition 1 voltage is between 10-32 V.
* The learned heater resistance is valid.
* The fuel level is greater than 10 %.
* The engine run time is equal to or greater than 5 minutes.
* The DTCs run once per ignition cycle when the above conditions are met.
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 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 100 s when the above condition is met.
