My CEL came on in my 98 Forester, P0141, O2 sensor Heater Circuit Malfunction, Bank 1 Sensor 2.....Easy fix? Can I do it myself? Anything I need to know about before I start?

Bad sensor, pretty straight forward, unplug-->unscrew (or rip off if corroded as I did in my case)-->replace with new and add anti seize.

Should be easy. Make sure the heater element is the problem (check resistance) and not a damaged wire or connector. Universal Denso O2 sensors are <$50 at Rockauto.

You will need to elevate the car on jack stands or front ramps to reach.

good luck

CEL came on today and this code was thrown. Since I plan on keeping the car for a long while do you think it's a smart idea to replace both original O2 sensors now?
