Detailed information on troubleshooting and repairing a p0031 automotive trouble code which refers to an oxygen sensor heater circuit that is low. also includes links to relevant forum topics on the code., p0031 toyota meaning air-fuel ratio (a/f)sensor need to reach a minimum operating temperature of 1200 degrees f to produce an accurate voltage signal..

As vehicles grow older, there comes a point when the oxygen or air/fuel ratio sensor’s heater circuit will probably fail. when that happens, the easiest fix is to install a new sensor. but when the vehicle comes back two days later with the same heater code, what then? a local shop called me in on […], catalog: http://www.autodiagnosticsandpublishing.com/software_catalog.html o2 sensor heater quick-fix the oxygen sensor heater maintains a sensor temperature....

This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precicely controls the amount of oxygen concentration that flows into the diffusion layer to limit current flow. this sensor can easily be installed and ensures longevity.
