Throwing same code after new sensor

[Graham Cole]

Hey guys! My 96 threw a code a couple weeks ago for the o2 sensor behind the cat. Changed the sensor and cleared the code but 20 mins of driving later and it's back, does anyone have any suggestions on how to fix? Thanks guys!

The converter is probably not efficient and that is causing the code, not the sensor.

That sensor monitors catalytic converter efficiency. If you replaced the sensor and still throwing the code, then it's a strong possibility the converter is bad. Or you have a crappy sensor. What brand did you use?

 

[Graham Cole]

It's saying the sensors inactive, like it's not plugged in

How's the wiring look?

 

[Graham Cole]

Good from what I can see but I'm gonna trace it all back

 

[jkeaton]

What is the actual code?

 

[Graham Cole]

I forget the actual term for it, a shop just says the sensor after the cat is in-active and to check my wiring

I need to really get myself a scanner

You can buy them cheap as dirt these days. Best tool you can have IMO.
