What does the p0031 code on an oxygen sensor mean?
P0031 Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The P0031 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit

What does the code p0131 mean on an engine?
What Does P0131 Mean? Code P0131 is a result of the oxygen A/F sensor incorrectly detecting the air to fuel ratio of the exhaust. This ratio is sent to the ECM which uses this data, along with comparisons to the outside air, to regulate the air to fuel ratio needed by the engine.
