Conditions for Setting the DTC
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
P0133
- The ECM detects that the HO2S 1 average response time is more than a calculated value.
- DTC P0133 sets within 60 s when the above condition is met.
P013A
The ECM detects that the accumulated mass air flow monitored during rich to lean transitions between 150-450 mV is more than 6 g.
P013B
The ECM detects that the accumulated mass air flow monitored during rich to lean transitions between 335-650 mV is more than 25 g.
P013E
The ECM detects that the Post O2 sensor voltage is greater than 450 mV and the accumulated mass air flow monitored during the delayed Response Test is greater than 20 g.
P013F
The ECM detects that the Post O2 sensor voltage is less than 350 mV and the accumulated mass air flow monitored during the delayed Response Test is greater than 70 g.
P0140

P2270
- The ECM detects that the heated oxygen sensor (HO2S) 2 sensor cannot achieve voltage equal to or less than 775 mV.
and
- The ECM detects that the accumulated mass air flow monitored during the Stuck Lean Voltage Test is more than 38 g.
P2271
