Does anyone what would be causing me to destroy the heaters in my o2 sensor. The original one that came with the motor broke. That got replaced with a bosch o2 sensor for a z32 tt, it's heater broke. Just replaced that one with a bosch o2 sensor for a z31. Does anyone have a clue why I am cooking heaters before a cook any more?

Any help would be greatly appreciated.

How many wires does your oxygen sensor have?

And, how do you know the heaters are going bad?

3 wire w/oval connector, heater resistance greater than 30 ohms
