Service Engine light refuses to go off. Fault Code P0134, states O2 sensor CKT Inactive (Bank 1 Sensor 1). Had already replaced this sensor with a Bosch, mechanic cut off plug from harness and wired in per directions. Rewired in different combinations, light still on. Different opinions for solution: 1. Can only use a Mitsubishi part, Bosch won't work. Buy Mitsubishi, wire it in since plug gone. 2. Still wired incorrectly. Bosch should work. 3. Need Mitsubishi part AND plug. Won't pass inspection 'till this light stays off, what's with the O2 sensor? Could I just have a faulty one which needs to be replaced or is it the wiring or is it the product or what? No one seems to agree and I am feeling crazy at this point. Please HELP!

Is this how I thank csmock132? Will try your suggestion and no matter what, I really appreciate your help. Will report the outcome. Is this how I thank csmock132? Will try your suggestion and no matter what, I really appreciate your help. Will report the outcome.

Can't afford the OE one, told that universal one should work if it's wired correctly. Will get the wiring diagram and do it myself, I might need help understanding the directions. Since the Fault Code states O2 sensor CKT Inactive (Bank 1 Sensor 1), can this be translated to mean that the wires are not connecting somewhere? Is that what the "Inactive" means? Plan to call Bosch on Monday to double-check that the universal will work with this car so long as it's installed correctly and that the OE might be preferable but if it's not affordable, I should be able to make do with what I have. Love this site. Glad I have my radio code written down and happy to find out what that darn clicking noise was all about (one more things to fix). Thanks to all.
