"check sensor, found open circuit" - what was 'open' - is that an assumption based on the code or did they test something?
once cleared - how long before the check engine light comes back on again?
how long has it been on?
has the engine ever been removed or any major engine service done (headgaskets, clutch, etc?)?
if you replaced the front O2 sensor and the code still reappears I would suspect the wiring has a short in it somewhere - which is more likely if there's been any major work to the vehicle. a connector or wire got crushed/compromised somewhere.
