P2274 - 02 Sensor Lean Bank 1 Sensor 3 - Code reset
MIL light came on on 2016 Range Rover Sport V8 and I checked the codes. Received a P2274 02 Sensor Signal Stuck Lean - Bank 1, Sensor 3
Replaced the downstream 02 Sensor (post cat) on the driver side. Verified the 02 voltages are fluctuating on the sensor 3 for both Driver + Passenger. There's a bit of variance between the driver + passenger side voltage still but it seems like it should be within spec.
I've reset the MIL and the code is coming back. Both of my reader tools indicate this code is a Permanent Code and even though I can successful clear the stored code.
Has anyone run into this code before? Do you need the dealer to perform the reset or should the reset tool be sufficient to clear the code?
