Bad o2 after 2-300 miles?????

[Dhos1]

Take a look at my PLX wideband o2 sensor after no more than 300 miles. Im going to try to clean it because im getting a no sensor detected error on my gauge....i just installed this thing wtf...i ran a few tanks of a 93/xylene mixture...but nothing else really wierd.

No sensor detected usually is something other than the sensor itself....
Plug it in, turn it on.. Getting warm?
Did you check for power to it?

Agreed.

Look at the instructions that came with. There should be a callout for the circuits. Check the plug pins.

Okay...fired the car up with the O2 sensor removed and after about 25 secs..it started to heat up....im thinking the sensors good. Possibly bad gauge

Ill recheck the plug pins for looseness....its crazy because it just worked..then "BAM"

Check the pins, then turn it on, out of the pipe, Spray some carb cleaner on a rag, and wrap the sensor in it...Get a reading, on the ga? If not, hook the volt meter to the signal wire, and see if you get a reading, if so, the sensor is working, and the ga is fubar.
