How did you test it? You need to let it get hot. Make sure the heater in it working, (Getting voltage and drawing current). Connected to the ECU or not? With the ECU connected you will see about .5 to .6 volts from the input amp. When working the sensor will load this down to near 0 until it gets up to temperature and begins generating voltage on its own.

It’s putting out zero voltage.

Stuart,
Have you used a voltmeter to check the O2 sensor while the engine is running? Even if your DVM isn't fast enough to follow the voltage exactly, you can see if is going above and below half a volt and get an idea of how quickly.

Well, maybe I will leave it as is, this van is exempt from testing. I still have a cold running stumble, and a slight idle surging when warm (900-1000, up and down) after the temp 2 sensor replacement. I'm pretty much out of options now, but I'll look for a vacuum leak before I turn it over to a shop.

It's not the lift, but having the oxy acetylene torch and knowing how to use it. I last wasted money on the Map gas torch some 25 years ago. It is really limited to brazing soft materials. Need to get steel red hot fast, your need the real deal. Must be nice to live in an area where a shop will remove a catalyst. Without the cat you may not need the O2 sensor. The O2 sensor is there to make the cat do its job.

You can do that because you have a lift! I've given up. Tried MAP gas with an O2 sensor crow's foot tool and could only get it 1/8th turn. At least NAPA loans those tools, but 7/8" is too big, and rounded the corners.
If the treads are buggered, the shop can replace the cat with a pipe & bung, I don't need it.

I use a Stilson wrench and a four foot heavy pipe as a cheater.
