Lexus GX 2004-09 :: TPMS Light Came On Steady
Oct 3, 2014
I had new tires put on last week. Two days after the TPMS light came on steady. All tires including the spare had 32 psi in them. That's what is listed on the door sill. I added a little more to 35 psi. Same result. I finally bumped it up to 40 psi. 4 shy of the max. It's been 2 days and no change. Since it's was a couple of days after the change is this a coincidence or is there some reset. I hate to disable it since its my wife's car. Also checked the switch under the dash.

I did the blue wire cut-mod 20 minutes ago. I had a consistent blinking TPMS light. I cut the correct, blue, wire and grounded to a stud behind the kick panel. The light is now steadily lit. Was I supposed to disconnect the battery first?

I have a 2009 Camry LE and I just got oem 2010 SE wheels for it. Upon start up, the TPMS light flashes for a minute then goes steady and stays on.
I know there is a reset switch in the glovebox but would that fix it? I went from 16" steel wheels w/ hubcaps to 17" oem SE wheels.

The issue is: when I start the Prius, the TPMS light blinks for about a minute before remaining steady. I have tried to reset the TPMS via the button below the steering wheel (knee-or-so height), but have not been successful (tried with the ignition in "ON" status, tried with "ACC", and as last resort tried in "READY")
My question is the following: Since I do not know all the history of the vehicle, how can i tell if its a sensor, the button, or something in the TPMS or ECU that's at fault? When I picked it up, all of the tires were a little flat (about 25 PSI).

Today I drove about 250 miles, round trip. About 75 miles from home, my TPMS warning light started flashing, then came on steady. I also received the Blue Link message about problems with the TPMS system. We pulled off the interstate at the next service station (about 3 miles) and checked all of the tires. All 4 read exactly 33 psi.
Restarted the car and continued on. After about a mile, the light turned off. About 10 miles later, the light started flashing again. It flashed for about 2 minutes then shut off again. We continued home without seeing anything more from the light.
The only thing at all out of the ordinary, is that the temperature has changed from a high of 35F earlier in the week to 70F today. There is a lot of moisture on the ground. Is it possible condensation may have affected a sensor? I have a 2013 GLS with 2800 miles on it.

I have had my 07 now for a few months. The other day during a trip, I noticed my TPMS light began to blink, and then stayed constantly on. I checked my pressures at the end of the day and they were all right where they should be, including the spare. When I start the car, the TPMS light will blink for some time, and then it will go steady and stay illuminated.
Took the car to a tire shop and they hooked the tpms scan tool up to the car and told me I had a bad sensor. I did some reading online today and it seems like a lot of people say the sensors that come from the factory for these cars only last for about 5 years until the internal battery dies.
For what it costs to get one sensor replaced, knowing that the car is 5 years old and the other 3 sensors are prone to fail, I see some people are making little PVC canisters and putting all 4 sensors in the canister and pressurizing it to make the light go away. But my sensors are broke, and if I bought new ones I do not have a tool to program them.
Is there anything that can be unplugged, or a wire that can be cut or grounded to make this stupid, pointless light go away or am I pretty much at the mercy of the tire shop/dealer to replace the sensor and make the light go away?

A couple of days ago the TPMS light started flashing on my 2004 GX. This morning I took it to a trusted tire shop. They checked each sensor, including the spare, and found they were all sending a signal. At 11 years old, and they are original as far as I know (I've owned it about 7 years), the tech said the signal may be too weak for the ECU to pick up. He didn't want to start changing sensors in the event it is an ECU issue. Not sure what to do for now, other than leave it alone. Is there a way to confirm the ECU is good? Do the scanners tell how strong the signal is?

TPMS light was on. It was the spare , added more air. Then checked the other tires, one was low too and added air. Now TPMS light stays off no matter what position the TPMS switch is in. The light used to come on when switch was in the 'wrong' position.

2005 GX470... Long time Toyota owner, first time Lexus with tpms. Light is flashing meaning a bad sensor from what I've read. Lexus wants $ to check and repair one wheel. Discount tire had a hand held checker and it found two bad sensors.

About four days ago my TPMS warning light started blinking. Same tires and sensors have been on there for quite some time. The service book says to take it to the dealer, but I instead stopped by Discount Tire (where I purchased the tires) to see if they could look and figure out which sensor was acting up.
When he ran his sensor, none of my four sensors showed up as broadcasting at all! Now I know that all four of my sensors did not just randomly go out at the same time.

Flashing TPMS for 1 minute, then steady = TPMS malfunction. The problem seems to be that the TPMS controller somehow resets itself wrong at some random point and begins looking for 5.5 bar (~88psi) instead of 2.6 bar (~37psi).
Here's the instructions for the fix:
I went into the adaptation I found in the Ross Tech wiki here : [URL] ....
All I did was enter the security access code (01503) then changed the values for each channel to 2.6 which equates to about 38psi. Once all of them were set to 2.6 bar, I saved and exited. Started the car and now I no longer have the TPMS error.
YES, the security code works for the 2010 GTI.

My 2004 RX330 which has gone many years without a problem suddenly has instrument panel gremlins.
I started the car a couple of days ago (it had rained during the day), and the airbag light did not turn off. Then the TPMS warning light came on, the water temperature gauge dropped to zero. The AC controls stopped responding. Since I needed to get home, and the car seemed otherwise fine, I drove home, after a few minutes the transmission "D" drive light went blank and the instrument back-light went to full brightness.
A few minutes later, all the warning lights went off and the back-light went back to normal. The AC controls still seemed to be off. A few minutes later the airbag warning light came back on, followed by the TPMS light and the back-light went to full brightness again. This cycle kept happening all the way home.
The next morning, hoping the problem had been some errant water getting into something, I started the car, opened the driver's door to get something and got back into the car, closing the door. The light showing the door was open stayed on. I put the car into reverse, the doors did not automatically lock as they usually do. I turned off the engine and restarted it, most of the other lights were off, the doors would lock; airbag & TPMS light came back on.
It has stayed that way, except I also get the A/T temperature warning light coming on periodically, and after some cycle it goes off.
I borrowed a car code reader, it does not seem to show any error codes. In reading some other postings it has been suggested that the Brake light switch is the cause, but the brake lights come on/off without any problem.

2-3 times a month the yellow TPMS light with exclamation point comes on, blinks about 10 times, and stays on steady. It's been doing this pretty consistently since I got the car, with one exception. I have a separate set of wheels & snow tires for winter and those have their own sensors. When I had those on the car for 2 months, I never saw the TPMS light. As soon as I put the OEM wheels back on, it lit again.
So finally I went to the dealer today. I figured it was a bad sensor. Naturally the light wasn't on when I got there. They scanned it and saw in the history a communication failure with all four wheels. They called Hyundai, then came back and told me that electronic equipment that I'm driving past can set it off. They mentioned banks & cell towers, among other things.
I don't think this is my issue. I travel the same route every day. The light comes on intermittently, sometimes when I'm on a rural highway away from any electronics. And I drive by plenty of banks and cell towers without it coming on.
So they didn't do anything for me. I'm at 43K. My concern is once I hit 60K and the warranty is done, if the TPMS brain croaks, I'll be on the hook for it.

Many threads on this subject, however my lights are a little different
When it first happened, on start up, I got all 4, which went away after about 1/4 mile of driving
Next start up I only have the ABS, VSC steady on and the TPS blinking. No "E brake light" lit like before and as others have mentioned.
The dash lights stay on all the time, even when shutting down and re starting. My rear brake lights work normally. Disconnecting the battery for about 30m didn't reset them either.
Lastly, I hooked up my scanner (Actron) and no codes were returned. Have the same symptoms and it still turned out to be the switch??

My 07 GS350 has SRS warning light on steady. I had my dash removed to fix dash rattle few months back maybe something was disconnected? I really didn't notice warning light until now since I rarely drive car.

GX 08 ABS making noise and comes and goes with steady interval during the drive. I did some searching and was not sure whether any other problems were related.
I think ever since we got new break pads installs it feels that ABS started to make noise with intervals non stop during the drive, I don't remember this ever being so obvious until the last couple of months.
The brakes feel fine, however when pressing break pedal when the noise comes up you can feel it in the brakes.

Thursday driving home from work, the thing started dinging and all sorts of lights started flashing at me. I looked in the manual and (finally) found that it is the TPMS. The orange light on the left side blinks for 1 minute and then stays on steady. I also see "Check System" in the display under the speedometer and there is a red light with an explanation point (!) on the right side. Checked all tire pressure. All were at 30 PSI. Checked spare, it was good. Manual says if it blinks and stays steady, contact your dealer. Called...they can't look at it until Feb. 12. I drive 40 miles a day on average. Not a lot, but by 2/12 that is several hundred miles. what could be wrong and if i should still be driving this car?

Today I spent an eventful day at the dealership getting oil changes on my IS300 and my GS430. After leaving with my gs430, my Tpms light came on. So I went back to the dealer and they ran a check to confirm it is the Tpms. My service guy didn't tell me which tire went out but I'm planning on getting rims in a couple of months. Should I just order order a new set of tpm sensors or just find out which needs to be replaced and replace it

So I recently got an '11 GS350 awd. No issues with the TPMS until today. In anticipation of next winter I went out and got a set of winter wheels with tpms. Yesterday I decided to hook up my new Techstream and program the second set of sensor IDs. When my wife drove the car today the tpms light came on flashing. I thought that meant that one or more senders was bad. Techstream showed four unique pressure readings for set 1 but had an error code for a bad sensor. Holding the learn button under the dash does nothing.

So I was running stock Lexus 17' rims on my 2008 c350 RWD. The time came to replace the tires and I thought- instead of shelling out hundreds of dollars, why not use my brother's set for free (his stock 17' rims from his 2006 GS300 RWD were just lying in the garage taking up space). They were also 17's. So, I swapped all 4 out, stock rims included. Drove around for a bit and noticed the TPMS warning light came on.
Not the low pressure light, but the actual warning light. This happens every day. The car is fine driving the first 15-20 miles but after that, the light always eventually goes on..then it's magically reset when I start the car the next day.
