O2 Sensor Not Working Properly

[BOOZTJUNKEY]

as above got my consult cable sorted today very happy with the product although it has shown an issue with my o2 sensor ....

It's showing 0 volts at the o2 while idling and driving ?

Sometimes while driving it comes on but the reading is not stable it just surges back and forth ...

Any ideas why I'm not getting constant power?

My fuel economy seems ok still bout 500 to a tank while granny shifting

Only thing I have noticed is I have a got a slight ping in third but don't think it's the o2 sensor because it shouldn lean it that much correct so apart from that all seems normal apart from the 0 volts it shows on the consult?

Any help welcome

the o2 sensor is only working when at light load, and when it isn't working it should run richer, not leaner, so the ping shouldn't be related to it not working.

as for the o2 reading surging back and forth, that is what it is supposed to do. at light load it should fluctuate.

i'd start by checking the plug and the wiring. sometimes they get damaged if they touch the exhaust and melt a bit. if all the wiring is fine then look at getting a new o2 sensor.
