Conditions for Setting the DTC
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.
P0130
- The ECM detects that the Loop Status parameter is open.
- DTC P0130 sets within 50 seconds when the above condition is met.
P0131 Lean Test
- The ECM detects that the HO2S 1 Voltage parameter is less than 50 mV.
- DTC P0131 sets within 2 seconds during the lean test when the above condition is met.
P0132 Rich Test
- The ECM detects that the HO2S 1 parameter is more than 1,000 mV.
- DTC P0132 sets within 2 seconds during the rich test when the above condition is met.
P0133
- The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is more than 0.1 second.
- DTC P0133 sets within 3 seconds when the above condition is met.
P2195
- The ECM detects that the HO2S 1 signal is biased lean.
- DTC P2195 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when met cumulatively.
P2196
- The ECM detects that the HO2S 1 signal is biased rich.
- DTC P2196 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when met cumulatively.
P2297
- The ECM detects that the HO2S 1 signal voltage is more than a calibrated value but is not out of range.
- DTC P2231 sets within 4 seconds when the above condition is met continuously, or 50 seconds when the above condition is met cumulatively.
