Conditions for Setting the DTC

WARNING: This page is about a different car, the 2017 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.

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 HO2S 2 average response time during the rich to lean transition is greater than a calculated value.

P013B or P013D

The ECM detects that the HO2S 2 average response time during the lean to rich transition is greater than a calculated value.

P013E or P014A

The ECM detects that the HO2S 2 sensor cannot achieve voltage below 450 mV within a calibrated time.

P013F or P014B

The ECM detects that the HO2S sensor cannot achieve voltage above 350 mV within a calibrated time.

P015A or P015C

The ECM detects that the length of time to change from rich to lean is greater than a calibrated value.

P015B or P015D

The ECM detects that the length of time to change from lean to rich is greater than a calibrated value.

P2270 or P2272

The ECM detects that the HO2S 2 sensor cannot achieve a voltage greater than 800 mV within a calibrated time.

P2271 or P2273

The ECM detects that the HO2S 2 sensor cannot achieve a voltage less than 100 mV within a calibrated time.
