I'm getting a code: 0036 Bank 1 rear O2 sensor.

So, I need part 191412 REAR OXYGEN SENSOR.

Does anyone know what the Bosch equivalent would be? I'm curious if I need the Maserati/Ferrari sensor, or if there's another alternative? Obviously I'm not talking a universal one that needs to be wired. I'm talking one that will just plug in and has connector already.

Thanks for your help and expertise!

Ok, I found the Bosch 0258006486, but it costs more than the one on Maserati Parts USA, which is $133. Anyone know another alternative?

Hi,

For my 2009 QP S 4.7 L:

Bosch 17171 is the Upstream O2 ($82 at Rockauto)

Bosch 16196 is the Downstream O2 ($50 at Rockauto)

(someone had posted 17001 as upstream O2 but this did not fit my car (wrong connector))

I replaced all 4 of mine - no errors but 83K miles on the originals.

Hope this helps,

Mark

Yes very helpful.
Thanks for posting the part numbers.
Thank you.. I'm glad it helps.

BTW I've found the CarBit app does a good job for sensor monitoring. It's a bit non-intuitive at first but really powerful. I have used CarScanner and purchased EOBDFacile ($50) but CarBit is now the only one I use (with OBDLink MX+ BT dongle) Screen shots attached.
