Is this is the correct part?

I bought a denso 234 - 4162 up stream AFR sensor (left in the pic).

The removed sensor from my truck is on the right. They look different but both has 4 wires in each.

Should I go ahead and use the new sensor? It will mount.

Yes, go ahead and use the new denso. The truck will run better than with the old one in.

Thanks... its raining here, but I am going to do it now!
Do I have to reset the ECU by unplugging the ground?

Thanks Drcoffee!!!!

 

[nissanh]

It truly runs smoother now.
The new denso says " toyota 89465- 04030" If anyone wants to know the what's on it.

Going to hit the road in few minutes

That one you replaced looks like some bobo sensor. I've never pulledoneoit of a T4R that looked like that.

Yeah, the one you pulled off is the "incorrect" cheapo sensor.

Thanks. My truck came with it. Someone probably replaced it with a cheap unit. Truck did 21 and within an year MPG dropped to 17.
Thanks!!!
