Thank you for your help. I have been getting conflicting reports about code P1135. I will try replacing the MAF and see if that solves my problem. Thank you. Don't replace it. You should clean it first by using some CRC Throttle Body Cleaner (the kind that comes in a spray can). Three or four blasts should be enough. Then reinstall it and clear the trouble code. Question - How do you clear or reset codes.

Hi, I recently purchased a 2003 rx 300 awd. a few days ago my VSC light & check engine light when on. I first check the gas cap as I heard that could be the problem. But lights are still on. I had it checked by a mechanic and it come up with a code 135. He said it was a bad oxygen sensor, bank 1, sensor 1. They want $203. at autozone for this sensor (bosch). I looked on line and they sell a DENSO one (not a direct fit) for 1/2 the price. Has anyone ever used this brand before? any problems? Has anyone have this problem before. Would this sensor cause both of those lights to go on? Car only has 47,000 miles on it. I also heard this would be covered under emissions warrany but lexus said no. Any help would be appreciated.
