Ryan Mior Posted March 11, 2012 Share Posted March 11, 2012 Hi there I am new to this forum but I am a long time Lexus owner. I recently brought my 08 rx350 in with all of these lights on and it was an air fuel sensor. I got it replaced. About two months later, maybe even less, the same lights came in and another air fuel sensor went. Apparently there are two separate ones. I have about 126000 Kilometers on my car. I am wondering if this is a common occurrence and are there any other problems I can expect at this mileage. I already replaced the battery and other than that these two fuel sensors are my other problems. Quote Link to comment Share on other sites More sharing options...
jaswood Posted March 11, 2012 Share Posted March 11, 2012 Oxygen sensors used as A/F mixture control ofte fail at that mileage level, both not far apart is not all that unusual. Quote Link to comment Share on other sites More sharing options...
