CinergiH20 Posted May 10, 2019 Share Posted May 10, 2019 Hello! I have a 2010 Lexus IS250 and the P2195 – Heated Oxygen Sensor (H02S) Bank 1 Sensor 1 – Signal Stuck Lean Issue was detected with a diagnostic device from Auto Zone so I'm not sure how accurate it is. Does anybody know where this sensor is located? My last Lexus had one located at the top, easy access. Goodyear quoted $400.00. My neighbor changed the $40. part for me for nothing. How much is standard pricing to replace P2195? My battery was dead for 3 days and I replaced it with a new one and after that is when the maintenance light came on. Could that have something to do with it? or I do need to get the oil changed; I haven'y driven much for the last 6 month and it was sitting a lot. Any advise is appreciated. Thank you!

RX400h Posted May 6, 2022 Share Posted May 6, 2022 A word of advice. Always buy OEM, if possible. I tried buying a low-cost aftermarket O2 sensor but it simply did not function. Heated sensors tend to be fairly expensive. Quote Link to comment Share on other sites More sharing options...
