Got a 2001 jeep Cherokee sport with California emissions. Got a P0432 code for a bank 2 sensor. I replaced all 4 sensors about 50,000 miles ago so I'm guessing it's time for a new one or two. Jeep also stated shaking a bit while in idle. The current O2 sensors I got are from auto zone which are Bosch. Does anyone know where I can get new ones online for cheaper or maybe a better brand? Unfortunately the O2 sensors are warranty for only 1 year. I'm only looking for the bank 2 sensors for now.

Go here and get NTK(NGK) O2 sensors. Look under emissions:

Here's your NTK Sensors.


Get rid of the Bosch.

Are NTK the same as NGK?

If so, I just paid $150 for the same sensor I could have gotten at NAPA for $50.

Afeared so:
