O2 Sensor Gone

[james-rav4]

Just some info :

engine light on

DTC was P1155 A/F sensor heater circuit fault B2-S1

Fitted a Denso which matched 89467-42020 from eBay. £74.50

Light has now gone out so looks like its fixed it.

should I disconnect the Battery to clear everything or will it be ok ?

Yes pull the Battery to clear the adaptations. It's not the end of the world if you don't do it. It should learn within 100 miles, but starting from a clean sheet is always best if convenient.

I changed 2 sensors on mine a while back and after pulling the Battery it drove really rough, almost stalling at lights for while until the computer started building its data back up. So don't worry too much if you experience a similar thing for the first few days
