Conditions for Setting the DTC: P013A
WARNING: This page is about a different car, the 2008 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
The ECM detects that the time for the sensor voltage to transition from 0.4 to 0.2 volt exceeds 0.4 second.
P013E
- The ECM detects that more than 4 seconds are required from the beginning of DFCO for the sensor voltage to fall below 0.14 volt.
OR
- The ECM detects that more than 4 grams of integrated air mass have passed through the system since the beginning of DFCO and the sensor voltage remains above 0.14 volt.
P0140
- The ECM detects that the HO2S 2 voltage parameter is between 0.401-0.519 volt, or that the HO2S 2 internal resistance is more than 40,000 ohms while the calculated exhaust temperature is more than 600°C (1,112°F).
- DTC P0140 sets within 4 seconds when the above condition is met for 60 seconds.
P2232
- The ECM detects that the HO2S 2 voltage and the HO2S 2 heater voltage changes are synchronous.
- DTC P2232 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.
P2270
- The ECM detects that the HO2S 2 voltage oscillations are slower than a calibrated value.
- DTC P2270 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.
P2271
- The ECM detects that the HO2S 2 voltage oscillations are faster than a calibrated value.
- DTC P2271 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.
