Help with wideband O2 sensor

[Rippinstock]

My cousin gave me his wideband off his part out two years ago. He had trouble getting it to work bc he cut some of the wires. Now i have pieced the wiring back together and tested them all and they work, but still nothing is reading, is there anyway i can check to see if the sensor itself is still working bc if so i would love to replace that? Any suggestions?

Install it and it should read ~ 14.7 at idle. If not, you have the bung already added to your exhaust for another sensor setup.

You can also check the reading in plain air, I am just not sure of the value that it would be. I know with my LC-1 that is how you calibrate the sensor. You remvoe it from the exhaust and in the open air press the calibration button. It compares the sensors readings against a predefined air constant value and from that comparision it changes its offsets and parameters to be more accurate based upon how the sensor is performing.

if it is reading nothing though

Maybe the sensor or harness are damaged

When you apply power the heater should warm the tip. Does that happen? Also what WB is it that you are using?

it was just given to me a few days ago, he told me fix it and its your. he installed it after he bought it new, but to install it he cut it (like an idiot) im looking to test it without installing it. Mainly bc im running stock exhaust and plan to upgrade in the near future. the wireharness i believe was tested and was good, but i need to sit him down again.

Which unit do you have?

 

[Rippinstock]

just found out it is a denso unit

When we ask what unit, we mean the manufactorer of the kit. You do realize that you need a WB controller for the WB sensor to translate its readings into something tangible and to drive the sensor. Then you take the controller's out put and you log that to get your O2 readings. You cannot just remove an NB O2 sensor and wire in the WB sensor in its place, it won't produce a usable value as the out puts of the WB usually range from 0-5V while the NB is 0-1V.

That is why we are asking for more info. You aren't explaining what you have.

Sorry to bring this thread back from the dead, but I have a ZT-2 Wideband which using the Bosch LSU o2 sensor.

I need to know how to test or verify the sensor without buying a new one.

I already emailed the Zeitronix guys, just waiting on a response, so I figured I would try here as shot out is coming up fast.
