Lexus GX 2004-09 :: TPMS Light Started Flashing
Nov 28, 2015
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?

I have an 09 ES 350 that I decided to put some very nice subwoofers and amp in. When I found out that I needed more power, I took out my spare tire and mounted a second battery in where the tire is supposed to go.
We'll sure enough when I drove the car later the TPMS light came on and started flashing. The system has to be able to read all 5 TPMS sensors. 4 tires and the spare. So when I took the spare tire out, the system thought there was something wrong with that sensor and turned the light on.
So what I did was I took a piece of PVC pipe and 2 PVC caps, drilled a hole in one of the caps, inserted a new TPMS sensor into the cap, then glued everything together.
After it dried I pressurized it to 35 psi, mounted it in my trunk next to the jack, and reset the TPMS system so the light would go off. Now the TPMS system thinks the spare tire is back and there are no more problems.

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.

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.

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.

Friday I pulled my steel gn 3 horse trailer about an hour each way. with the horses it weighs right at 7000 pounds. no issues. Saturday morning I drove to town, no issues. Saturday evening, I got in it to run down the road and about 2 miles from the house, the check engine light came on and the tow haul light started flashing and the temp gauge is dead. drives and shifts normal, tow haul button still functions. Truck is stock except for an EGR delete. No tuner, FICM was rebuilt. I had it on a battery minder before I left and was thinking about pulling the batteries and letting it sit for a while to see if it clears. Scan Gauge II shows no codes.
Sunday: So I let it sit all night, batteries connected and it was completely normal this morning. will see what happens when I drive it to work tomorrow
Later Sunday evening: So I just took it out for a test drive, went a couple miles down the road, shifting normal for a cold start. Temp gauge is working, just as I am almost back home. 5 miles at the most, temp is coming up to normal, gauge goes dead and check gauge light comes on and tow haul starts flashing. I think it might be the sensor.
This morning: I got about 6 or 7 miles from home, trans just got up to temp, pulling up a hill, it shifted out of overdrive, tft gauge went dead, check gauge light came on and the tow haul light started flashing. still shifts like it always has and the tow haul button still functions.
I am thinking it is just the temp sensor. Truck has 159k on it.

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?

My 2007 ES350 had a problem with the TPMS where it would flash for the first minute and then stay solid. After checking all 5 tire pressures and resetting the system by using the button under the drivers side dash, I determined that it was probably a bad sensor. Seeing as how they are 7 years old, this seemed reasonable. (I also checked to make sure the passenger side button for the second set of tires was not pushed).
I just had new tires installed at Costco, and brought 5 new sensors for them to install. They supposedly did whatever sensor registration magic is required, but I am still having the same issue. The light blinks for the first minute then goes solid.
What is interesting is that when I try to reset using the button, the light flashes slower (about 1 per second) 3 times, then goes faster (about every half second or so) for the rest of the minute. Is this some code that the system is trying to display?
Also, is there any trick to getting this system re-initialized that I can pass on to the Costco techs when I take it back up there?

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.

So today I upgraded to a set of 18" interlagos from 17" denvers. My TPMS light is flashing then stays on (malfunction). Do I just need to reset settings via vagcom?

A customer brought in their 07 Camry XLE with a flashing low tire light. I retrieved two codes, one for sensor 1 and one for sensor 2. Tire pressures normal.
Codes are
DTC C2121/21 No Signal from Transmitter ID1 in Main Mode
DTC C2122/22 No Signal from Transmitter ID2 in Main Mode
The other things I noticed were that the two bad sensors were showing a temp of -40F while the two good sensors were within 5 degrees of actual ambient temp. Another fault was that the battery in #4 was low. I ordered 2 new sensors from Toyota and after writing down their code, I swapped them out. I had already written down the codes for the other 2 sensors. Going into the data, now sensor #4 is reading -40F too and the battery says OVER.
The only good one is on the left front. I cannot believe that I had two bad sensors this morning and another failed this afternoon. I've been wrenching long enough to know that these things are rare. The customer made the appointment yesterday and dropped off the car last night. She called right when the light came on and only drove it about 30 miles from then to when she dropped it off. Before I left, I ordered two more sensors. BTW, the tires look relatively new, but we did not put them on. The two sensors I removed looked fine.

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%
[Code].....

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.

So I was driving my 2004 6.0 auto on the freeway today when the tow haul light randomly started flashing, nothing felt wrong until I stopped, then when I went to pull away it wouldn't shift down from 5th according to my livewire ts says under the commanded gear gauge. It shifts into 6 and overdrive fine. I turned the truck off, the light went off but as soon as I put it in drive it jumped around from 1-2-5 and back down until it locked in 5 again and the light started flashing again. What this could be?

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.

This will be my first winter using a dedicated set of winter tires and wheels on my 09 Camry. The set doesn't have TPMS sensors. Will the TPMS light constantly flash or just stay lit when the system doesn't detect the sensors? I could live with the light always lit but if it flashes it will be annoying.

Okay, so after 42k miles, I had to bite the bullet 4 months before my lease is up and put yet another set of tires on my T2. Done today at reputable shop, and the TPMS is not yet registering the monitors on all four wheels. Driven about 8 miles since and they are still not registering. The indicator light is flashing for 60 seconds to indicate no signal. Should this rectify itself with some driving, as other systems on the Treg do, or is it something else. They were working immediately prior to them mounting the new tires.

I have an Avalon 2009 with the TMPS indicator blinking for 30 seconds when the car is started and won't go off.
I think this might indicate an issue with the sensor? How do I know which one and how to replace it?
Also, I cannot release the trunk from the button in the car (by my knee) or the trunk release button from the remote.
Does the TMPS light blinking and staying on has anything to do with that?
In the past, when I had a rear signal bulb went out, I couldn't scroll down my window either. Once I replaced it, I was able to.
I wonder if the trunk being locked from automatic release methods is the result of the TMPS light being on.

Maintenance light is Flashing on and off after initial startup, could it be that its trying to tell me its time to change oil or could it be something else. It is time to change my oil based on the mileage that it was last changed.
