Camry :: 2007 XLE TPMS - Flashing Low Tire Light
Oct 30, 2013
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.

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 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.

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.

What is the tire pressure that will trigger the TPMS to activate the warning light on the dash? I had 31psi in my left front and got no warning?

My Tire pressure indicator light starts FLASHING after driving for 15-30 minutes. It does not stay on but continues to flash every 3 seconds. I stop to check tire pressure and my tires are fine. After a couple weeks of this, I took it to the Subaru Service who checked the tire pressure indicators and it said all 4 of them were bad. They reset them versus replacing them and 20 minutes after I left the subaru service center, the flashing started again.
Subaru says that it is unusual for all 4 to be back at the same exact time and recalibrating them should have fixed it. Now they would like to replace each of them for about $150 parts&labor EACH. That seems crazy. Is there something else wrong? Something else they can fix? Is this a legitimate repair? My subaru is the Limited LL Bean version, 6 cylinder, has 60K miles on it and is in top condition. Had new tires put on 10,000 miles ago.

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?

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?

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 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?

I was wondering if the spare tire could cause the TMPS to go off because i checked all four wheels and they are at 39 psi just to be safe and still its on.

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?

So tonight I'm driving on I-80 and all of a sudden I hear a thud, the TPMS light comes on and a warning of low tire pressure. I get out to take a lot and the rear left tire is practically flat. Changing the tire was pretty easy once I figured out where everything was in the tray.
So now I'm in the market for a replacement tire as there was a huge hole in tread. I have a about 3000 miles on the car. Would you get a replacement tire that is the same make/model as the rest of the tires, or would you simply get a cheaper replacement? Once I am ready to replace the rest of the tires, I'm not sure if I would replace them with the OEM make/model anyway. At the same time I'm not sure how long the OEM's will last.

So I feel like this is more of vent than anything but anyways, it all started yesterday when I noticed one of my tires had the TPMS light pop up. I went to the gas station on my way home and put some air in it and everything was good. This morning I get in my car and its the same tire but now at 7 psi so I have a leaking tire. I bring it to costco to see if they can do a quick tire repair instead I find out my alignments been screwed up and it has worn down all 4 of my tires on the inside. I saw it for myself and its been worn down on them pretty bad. I'm in the process of getting the Michelin Pilot Sports by tomorrow and will need to get an alignment.
Lexus dealership didn't catch this when I brought it in last month for an oil change and they did their so called "inspection." Maybe they don't check for alignment issues but wouldn't they have noticed the uneven wear on my tires??? Also my IS350 is all stock and isn't dropped or anything. Why my alignment would've been messed up?

I was driving doen the road and and all of a sudden I get a message to check the tires and the TPMS light was on. So I pulled over looked at the tires none looked flat. So I continued to a gas station to check the pressure. The pressures were fine, I had just installed my steel wheels and winter tires on Friday. What could have caused this and how do I reset it?

I just got st coils and apr stg1 software put in my car and love it. the question i have is the other day my tpms light came on, so when the guys installed my software (today) the tried to set the pressures and clear the light and it wont go off i want to take it to the dealer but I don't want them to give me a hard time about the mods.

First cold day of the year today and naturally my TPMS light came on. Checked the pressures with my own gauge, all at 34 psi. Inflated them all to 38psi and the TPMS light is still on. Drove a little ways - still on. Checked pressures again - still 38psi. I had this happen once before in mid-winter two years ago and I can't remember what I had to do to reset the TPMS light. Mine isn't one of the ABS/ESP systems so I don't have a reset button - I need to do something with the VAGCOM but I don't recall what.
What's weird is that the TPMS threshold should be 7psi per wheel shouldn't it? And my light came on when it was only 4psi down. Is there somewhere I can check and find out what the ECU thinks the threshold is - again with my VAGCOM?

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.

I had a leaking tire replaced and my TPMS light was on. I proceeded to go ahead and reset the TPMS system after checking the pressures. The light blinked slowly 3 times, but then blinked fast for quite some time before turning solid again.
After pressing reset button with 3 slow blinks, what does it mean for the TPMS light to blink rapidly for a minute or so before turning solid.
I highly suspect that the guy changing my tire either damaged or did not reinstall my TPMS sensor. Im kicking myself for letting them touch my car since they are so shady.

2008 Honda Civic Coupe with 26K miles. One tire keeps losing air & idiot lite comes on. Can this 1 tire be fixed? Or do I need to buy 2 new tires? I do know that one tire had a nail in it and was patched, but I've lost track of which one it is.
