1995 240SX SE - Is this the O2 Sensor? Looks like 1 Wire???

[gtd65]

The O2 sensor has failed following Error code 33 given at Autozone.

It appears that the 3 wire sensor may have been replaced with a 1 wire variety in the past?

See this pic and please confirm if this is indeed the O2 sensor?

That's your primary O2. You can get a Bosch replacement for ~$17.

Thanks for the quick reply

The part has a Boshe & a number on it.. "a24 620 033...." something more but can't see right now.

So does this mean the sensor has been converted from the original 3-wire type or did the early '95s have single as standard?

I'm assuming the black tape around the silver tubing is where it was modified?

If it just requires the $17 part thats good enough for me

Like this one?
