Read P0058 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P0058 closes out the heater family: bank 2 downstream, circuit high. If several heater codes from different corners of the exhaust arrived together, resist the urge to price four sensors - shared fuses and relays explain simultaneous failures far more often than coincidence does.
If this one arrived alone, the standard sequence settles it: verify the fuse, measure heater resistance at the sensor connector, then check for supply voltage with the key on. Three measurements, one answer, no guesswork.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.
