Customer arrived with check engine light on.  Complaint was loss of fuel economy at the same time the light came on.

Ran Snap-On Modis diagnostics to determine problems. Found Oxygen sensor heater circuit to have malfunctioned. Checked integrity of circuit, tested good.  Tested sensor, failed.  Replaced sensor, reset PCM. Back on the road.
