dlawall Posted August 14, 2007 Share Posted August 14, 2007 I have a check engine light with a code that gives a mass air sensor problem. The car has less than 70,000 miles on it and the mass air sensor was replaced at less than 40,000 miles. Could this be a bogus code caused by something else? The check engine light has been on for months and there is no difference in performance or gas mileage. Actually I don't think that there was anything wrong with it the first time when the dealer replaced it. Quote Link to comment Share on other sites More sharing options...
00RX300 Posted August 16, 2007 Share Posted August 16, 2007 It looks like you have been waiting too long for a reply or advice... Here's my experience with my 2000 RX300: If the code was for the MAF, I'd try cleaning it and deleting the code(s). If they come back, it might be something else or the MAF is faulty again. There are excellent directions on cleaning that sensor on this forum. At around 65K, I had to clean my MAF and the code did not come back for a couple of years (at which time I cleaned it again). I'd also search this forum for your code number. You may find other possible causes (like maybe one of the O2 sensors). Good luck, Bob Quote Link to comment Share on other sites More sharing options...
