O2 Sensor Bank 2

[AlSalas131]

Just got an engine light related to the O2 sensor bank 2. Should I clear the error of getting these measures or the sensor needs to be replaced?
Thanks in advance for insight!

Not saying you have to replace it, but i just ordered spare O2 sensors and DP temp sensor. Was surprised how relatively inexpensive they were (compared to Alfa Romeo OEM parts)

I'm surprised they were readily available. Getting parts from Lotus seems to be a hit or miss situation at best.

Are they Toyota parts?

Are they Toyota parts?

docron has the AMG version, not the Toyota V6.

docron has the AMG version, not the Toyota V6.

I was about to say I remeber looking into these and they were like $300 a pop for the v6 ones

I had one replaced via warranty last year and have the EML light again - different code. Going in again under warranty on 7th July. Frustrating as have reduced acceleration, 4k red line limit and poorer fuel economy. Cancelling light just brings it back on the next time it’s started. First replacement seemed to sort it for 8 months until this EML issue.

Can you get a graph of the two O2 Sensor Voltages please, like 1 minute in idle. Don't touch the gas.
If your app doesn’t support it, use "CarScanner" from the appstore. Blue background, white engine symbol.

Here is how you debug whether you need new O2 sensors, or if your catalyst failed:

P0420 simple?

I've popped a P0420 code that has returned each day. I've read through many posts regarding trouble keeping the code away. I'm hoping I simply have a bad O2 sensor. QUESTION: Has anyone experienced the P0420 pop and simply changed the 02 sensor, ultimately fixing the problem?!?

Your pre-cat O2 sensor being 0.0V is suspicious, but only if it's flat-lining at 0.0. Like @Kimmax said, log your pre-cat and post-cat O2 voltages over time, once the car is up to normal operating temperature.

I had codes P0161, P0158 and P0116. I cleared them and had the o2 sensors replaced under warranty a couple months after I got these codes. If you are planning to go to the dealer soon, I would not clear the codes so they can easily see the codes.
