Thanks. Is it hard to remove the gauge cluster? I found a diagram for the instrument panel of RX300. There is only one bulb there in the diagram. The other warning lights are working properly. Does it have one bulb for each warning or one for all of them? Jason

I just noticed that the open door warning light on my 2000 RX 300 is never on even the vehicle doors are actually open. This is quiet dangerous. Is it fixable by myself? Your suggestions are appreciated. Thanks, Jason

Thanks. Can you please elaborate where to find and how to reset the plug? I'm novice but eager to learn. BTW, the ECL has not come on for two days. Jason- When you open the hood look straight down on the front exhaust. You will find what looks like a spark plug with a 4 wire lead on it and a plug at the end of that lead. That is your front A/F ratio sensor. (the one that triggered the P1150 code) Refer to my last post as to how to "reset" the plug. The plug I'm referring to is the plug on the end of that 4 wire lead. Thank you for your help. The CEL is off for 2 weeks now.

Many thanks to everyone for your help. In my original post, I mistakenly said o2 sensor was bad. I've edited the post. Jason

Dear Experts, My 2000 Lexus RX300 has only 93K. I replaced the alternator with OEM part in an independent shop that specializes in BMW but also do some Lexus work. The alternator was making noises and the noise was gone after the replacement. However, my engine light is on with code P1150 the day after the alternator is replaced. The code means front bank air/fuel ratio sensor needs to be replaced. Today(two days after the alternator work) the engine light is off. How often is this code rechecked? Do I expect it to come on and off? Can I drive this car for a 600 miles trip tomorrow? If the sensor is indeed bad, will the engine be damaged if I keep driving it for short or long distance? Could it possibly be related to the alternator work that was just completed? They quoted me $275 to have the sensor replaced but I'm not sure I can still trust them. The shop did touch the air filter as they told me it needs to be replaced. I examined the air filter after wards but has not yet replaced it. Could it be possible that my repositioning of the air filter actually fixed the problem since the engine check light went off not long after I touched the air filter? Thanks for any help in advance.
