the ect sensor and gauge are seperate that's why the gauge still works. check the wires at the ect sensor plug they may have broken. that's what happened on my car. you're better off putting a good o2 sensor in and letting that take care of closed loop for you. and tune wot ( unless you take somewhere and have it tuned). or if you have v3 just have that simulate a narrowband signal for the o2 and just use your wideband
