Hi
I have a Zeitronix WBO2 sensor which has been working butifuly. But starting the car the other day it was stuck at 21.0 and not moving. I am sure it has nothing to do with the air/fuel mix, but rather that someting is wrong with the wiring or the sensor it self.
Has someone experienced something like this? Is it a faulty sensor or might it be a faulty wire?
Here is the car in question. Running realy strong at the moment![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

It's probably the lead. They're pretty delicate and brittle. I've had this happen twice. May also be a faulty O2 sensor, but unlikely.

Right could be either -- disconnected/broken/melted harness wire, or the sensor is shot. Both have happened to me.
When my sensor(s) burned out, they got sticky/sluggish before they burned out for good.

Thanks guys,
I will check the cables before I order a new one...
Wheels are boxster 2001 wheels. These are actualy a hidden gem: As far as I understand these are the lightest original porsche wheels around in 17" They are 7.5 AND 8.5 with Toyo R888 225 front and 255 rear.
Not many run these on the 944
