Bank 1 Sensor 1 Located in the rearward bank exhaust manifold.
It is recommended using Denso sensors, as they are the original equipment.

The search engine above, using the Pxxxx error codes, should give you a little more explanation.

palaka,

If you still get issues after trying to solve it let me know, though what Tammy mentioned is what we have discussed together as a group in this forum.

thanks guys

Ok guys, could this two codes, if used for an undetermed ammount of time, can it lead to the pre-cat failure?

Mine went boom!

Tammy

This sensor seems to affect the fuel-air mixture for the bank of cylinders.

The newer design of three stage catalysis aren't as durable as the older (bead type) catalysis. Much better functionally, just not as durable. They are known to catch fire if the fuel mixture is incorrect. I would imagine a boom is also possible.

You may need to replace the sensor and the catalytic converter..

In my case, the precat got clogged and I am sure it was overheating even though it was not red hot...but I had to drive it really slow.

Regarding the codes...there is from my reading a sort of default (not necessarily limp) mode with the ECM when these issues occur on the RX300 where you can keep driving it, not that you necessarily want to continue driving it.

Thus, as I mentioned in another post, I do not think this is what caused the problem with the precat. Bad fuel did me in.

So, my check engine light came on in my 2000 RX300 the other day. I check the codes and search the CL forums and find out the problem is the O2 sensor (upstream, near the firewall). I get online to find a replacement O2 sensor and find some Denso O2 sensors ($160) that will work, but being the busy and impatient person that I am. I wanted my O2 sensors today. I call the Lexus dealership and they wanted $280 for an O2 sensor. I thought for a minute and decided to see if a Toyota Sienna O2 sensor would work, since it is the same engine. I called the Toyota dealership and it was only $140. So I bought it. During the installation I realized that the plug is slightly different. The plugs were the same shape but the Toyota one had an extra tab on the plug that wouldn’t allow it to fit in. So to fix the problem I just cut the plug off and soldered the Lexus plug on the wires. They are the same colors, I just matched the colors and soldered. So far it has worked and no check engine light, it has been 4 days. You could modify the Toyota plug to fit, but I found it to be easier to just replace it with the Lexus plug.

I was worried about damage to my catalytic converter when my check engine light came on and I ended up going about 1,500 miles with it on because I was on a road trip and then had to order the part. When it came on during my trip I thought it was something else because I had large elevation changes (figured that may have been the thing that tripped it) and because my car ran the same and the mileage did not change when it came on.

I don't know how much the engine management system can actually change things when it comes to the mixture (how rich it can make it), but even if it does not cause a fire, it can certainly shorten the life of and effectiveness of your spark plugs and converter.

I can tell you from experience making trips out to Veracruz and up to the U.S. border, where there is a 7,000+ foot elevation drop...P0171 error codes will light up...even when my RX was still stock engine wise.

Went to the STealer and ended up couching up $1,500 for the second pre-cat. If I wasn't in to much of a hurry to get the wife rolling again, I would have gone to the states to pick one up for less but then again, I would have to add the plane ticket.

Any quotes for that Pre-Cat section from the dealers up there?

Hope it didn't send fragments to the main cas as I was quoted close to two grand for it!

Lexmex

Wow...those prices are high. I am not sure what the precats are going for up in the U.S., but my imported Magnaflow cat went for under $300 USD installed down here in Mexico Cit.
