Need help - O2 Sensor

[Josh_MCE]

Hey guys,
Was having codes pop up for low voltage O2 sensor bank 2.. never had an issue with the O2 sensors, car has 105k/km so decided to change all 4 at the same time.. Bought 4x GOSS O2 Sensors ($450) from Auto Pro and replaced myself.. Im now getting stability control fault and vehicle goes completely sluggish - scanned the codes and now all 4 sensors are showing heating faults.. have I done something wrong installing? What could be the problem for all 4 to now be showing faults

All 4 wow! Are you sure you bought the right ones for your model?

Im starting to doubt I did.. They matched the sensors compatibilities through their computer to my rego - but for all 4 to be throwing the same code, it may be the issue.. GOSS seem to be a credible brand, so don't think they're just too cheap

Can you look them up on the net somehow?
The loom hasn't come unplugged somewhere has it?

 

[Josh_MCE]

Don't think its a loom problem - because all 4 are showing the same fault
