Tire pressure sensor
2008 LS460 with 200k+ miles. Alarm saying to check tire pressure monitoring system. Is there a relatively simple fix for this, or could this get expensive

It's most likely your TPMS transmitters need replacement. Including spare tire. Most tire dealers can test and replace for you.

If the warning is to have the "tire pressure monitor system checked by a dealer" typically that means that one or more of the 5 tire pressure sensors my not be reporting, This may mean that one or more tire sensors is defective but may mean there is another problem.
The advice from swfla in post above is excellent. TPMS problems are most cost effectively addressed at tire dealers and not car dealerships.
The TPMS is one of the most reliable features on the LS460s, only requiring occasional benchmarking and sensors replacements typically once every 7-10 years. The TPMS enhances your safety, improves tire life and gas mileage. It provides the most benefit when it is benchmarked correctly and tire pressures are seasonly adjusted.

Who quoted you $800? A Lexus dealer?

Funny that this thread just started as a couple days ago I got the check the TPMS system warning. It is reading 4 of the 5 tires.
My car was built in May, 2007, and these are the original sensors, so they lasted almost 17 years!
I have to bring it to my independent mechanic, but I know it will significantly less than $800 if I have all 5 replaced.

Wow, 17 years is a long time.

Ouch, my local tire shop will do them for like $35-40 each. I have one that is out, so it's giving the "light". I have replaced 3 so far.
Normally don't need to replace all of them, they can check to see what one is no longer reporting and change that one...

I got mine replaced (5) when purchasing new tires at Costco. I remember paying about $140 installed including the sensors (aftermarket popular brand sensors.) Cheaper when buying new tires.That was several years ago and have never had any problems.

My Lexus dealer quoted $1250 a couple of years ago for all 5! I got them done at Discount Tire for around $50 plus $300 for the sensors from Bell Lexus (online).
Cold weather can reduce the voltage of the sensor batteries so its not surprising people are seeing issue this week.

The problem for many is that the cold reduces the tire pressures. Proper inflation and benchmarking will solve most of the problems.

I'll probably only replace the one that is out. I just had new tires put on last fall. If the sensor had failed then, it would have been the ideal time to change them all.

Yes, I was thinking cold weather might have something to do with it. Since the one sensor failed the low temp has been 6 and the high about 19. Today it finally got above freezing, but only barely, 36.

Oh, and just as an aside, I remember being on here when my car was about 5 years old and this topic came up. The consensus was the batteries would last 5 to 7 years. Around that time I was having new tires put on and was thinking maybe I should just have the sensors replaced. I guess that would have been a little premature!
