O2 Sensor Help
Hey Ladies & Gents
Currently own a MY2010 IS250.
Been having some Rear O2 sensor problems. My Bank 1 Sensor 2 has not been reading properly (passenger side; LHD car)
I just replaced the sensor today and looking at my readings, the ECM is not reading any value out of B1S2. Making sure about readiness, I checked B2S2 and the ECM is getting readings and passes readiness with the same O2 spacers. No exhaust leaks. No physical reading out of B1S2 at all.
I am catless and have rear O2 Sensor spacers but that is not the issue as Ive checked to make sure theres no blockage.
Anyone able to assist with why I'm not getting any readings out of Bank 1 Sensor 2 after replacing with a new one?

I assume you inspected for damage and double checked for secure electrical connection.
If the wire length on both sensors allow.......I would swap sensors and see if the situation follows the sensor.
If it follows, exchange the faulty sensor with another new one of different manufacturer...... sometimes a new part from particular manufacturers wont function properly on some vehicles.
