Hello I am new on this forum but I have been reading and searching on it for sometime. I have a 1999 Lexux RX 300 and a few months ago my check engine light came on. I searched the forum and followed instructions to get it off. The main code on this problem is P1133 Fuel/Air metering I also have a P0446 code.
I have performed the following : reset the system, removed the EFI #13 fuse, cleaned the sensor that goes into the air filter cannister and replaced the air filter, replaced the gasket on my gas cap, and the damn thing is still on. It will go off after re-setting the 13 fuse or taking the bat cable off but it will always come back on in a hundred miles or so.
Nothing seems to be wrong with my vehicle other than that damn light and now just yesterday my "BRAKE" light came on and stayed on. The emergency brake is released properly the brake fluid is full (maybe a bit too much) the "Brake" light will go off if I unhook the sensor at the brake fluid cannister. It comes back on when I plug it back in. I am so stressed.....at these lights with nothing seemingly wrong with the running of the vehicle. The truck as 110,000 miles and runs great, the lights just bug the hell out of me and I do not feel like getting "screwed" at some Lexus Dealership. I found a bulletin on the P1133 Code http://www.clublexus.com/index.php/article/view/1944/1/115 and also
http://www.clublexus.com/index.php/article...view/267/1/115/ for code P0446
but my vehicle is not under warranty. Can someone please help me? I like things to be right and at the rate my lights keep coming on my dash will soon look like a christmas tree.
