Prius (2010-12) :: Tire Pressure Light Illuminated On Dash
Feb 2, 2012
Our winter tires on the 2010 prius have the pressure sensors insalled in the wheels. Yet, ever since they were installed, the tire pressure light has been on on the dash. I have checked the tire pressures numerous times, and they are okay. In fact I now have the tires slightly over inflated instead of at spec, and it's still on. Do the sensors go bad in the wheels? We've had no issues with the system with the summer tires and wheels.

So we had a subzero weather week last week and on one of the below zero days by low tire pressure light goes on - on my dash. I've checked all 4 tires and they are not low. Do I have a bad sensor? Or is the cold causing this?

Quick Question: I was driving through my neighborhood yesterday and hit a pretty good bump. I as hit the brakes, a quick Yellow Triangle Light illuminated on my dash. There were no other warning lights that I could see and the warning light was only on for a split-second. What could've caused this? BTW, I have a 2013 Prius LB 3 purchased new in August w/ only 1230 miles as of today...

My car's driver's side tire looks almost flat as one of my co-workers indicated first but the tire pressure light is NOT on. Should I worry about it and get it checked out?

This morning my TPM light came on. I stopped off at a service station and checked all the pressures, but they were all fine. Is there is history of faulty sensors?

It was very cold in the morning yesterday and my tire pressure warning light came on. I had a funny feeling that it was related to the temperature but it didn't ever go off so I called Toyota today and they said to drop by with it and they would check it out. On the way there after work I got rear-ended. So sad. I thought it was just the bumper but the hatch won't latch properly so they said they would have to 'pull something out...". It was going to be about $800 for a new bumper but now will be more. I'm going tomorrow to see their collision guys about a quote to fix it. My poor car. I have to admit that even with a dented bumper the car still looks good!!! I don't know how I'm going to manage for the two days it takes to get it fixed. I have to re-learn how to use one of those key things.
The Toyota service person told me that he had 14 cars in today alone to reset the tire pressure warning lights that came on because of the cold weather. He said my tire pressure was fine. Just my bumper needs a little work.

I think my tire pressure warning light is malfunctioning. I check all the tires with different tire gauges and they are all showing around 40 psi. I reset the system by holding down the button and let the light flash 3 times after I check them. It is only sporadic and does not stay on unless one of the tires is low. I did have a loose valve stem, that I tightened myself. When it does this it seems to come on and flash before going off and does not stay on. Sometimes it stays on for a little while and then goes off. Could it be a bad sensor?

A few days ago our 2010 with 87k became immobile with "Check Hybrid System" illuminated on dash. Dropped it off at the dealer who had it all day. Replaced the "transistor kit" part number 04899-47021 and blamed the failure on the recall. Recall was not completed. Wife felt a jolt while driving home but no warning lights illuminated. Next day she tried to start it and got that message.
Codes pulled were p3004 with info code 800 and p0ad.

I am driving down the road and the TPMS light starts to blink - and then stays on. I looked in the manual and it says that "When the light comes on after blinking for 1 minute: Malfunction in the tire pressure warning system." The resolution is to "Have the system checked by your Toyota dealer."
All my pressures, including the spare are how I have them set. I also made sure to re-set the TPMS button under the steering wheel to the new pressures and everything. I'll let you know what I find out. I'm kinda mad a sensor has failed though on a car that's less than one year old.

My 2010 Premier Mountaineer apparently has pressure sensors, because i am getting a warning on the dash. They were down about 4 lbs all the way around, so I topped em off. But, the warning still comes back.

When I bought a used camry 5 years ago and drove it on the highway, my front tire busted and damaged the fender cuz it had too much air!! I wonder if it shows high pressure on my 2010 gen III Prius v with ATP. I know that the tires are special on this v version but still I like to keep a slightly higher pressure in the front ones because the lane keep assist feature works better with higher tire pressure. Summer is coming up so that gets me worried what to do with tire pressures.

Do cold weathers cause tires to deflate? On my way to school today I noticed the tire pressure light. I've had the car only for 3-4 weeks. Never had any issues with it.

I have a 2010 F350 that has been throwing the "tire pressure monitor fault” on the dashes info center. Here is where it started. I purchased new wheels, tires and sensors a few weeks ago. I put them on and they were fine on the way home because I assume that the stock ones where still being read (they were in the bed of the truck). Put the old ones in the garage and then while driving to work the next morning I got the message. I tried to reset or “learn” the new sensors that night with no luck. There are two ways to get my truck into learn mode. One uses the hazard flashers then releasing some of the tire pressure until the truck horn beeps. The other method is a series of break pumps and turning the ignition from on to off then using the TPMS tool that apparently comes with the truck.
The truck went into learn mode every time with either method but it would never recognize the new sensors. After attempting everything on the sensors I checked to see if for some reason the trucks actual monitor was in a “fault” mode. Last night I tried relearning the old stock sensors with great luck. They all were recognized… for about 10 minutes. After getting them to work I left the shop I work at and on the way home the "tire pressure monitor fault” came back again. So just in case something had been in sleep mode when I did it I pulled over and reset them once more. Again with great luck… until this morning on the way to work again it went back to fault mode even with the stock wheels still in the bed.

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?

I filled all my tires with air, and the light still won't go off. It's winter so I don't know if that comes into play, but all my tires are at 30psi....

Is there a way to view the tire pressure on the Prius? I've gone through the manual and didn't see anything. my LaCrosse had this function and it came in handy.

My TPM light went on coming into work this morning. I did a visual check, everything looked ok. When I got to work got out the old gauge and they all show about 28 psi. The manual states it can go on due to 'natural causes' but doesn't really go into detail. Will it goes on if any/all tires fall below a certain psi? I'll be going back out later to check again to see if one of the tires is going flat.

My warning light for my tire pressure came on, I fixed the tires and now it won't go off. Is there a reset button I need to press? I can't find it in the manual ...

the indicator light is on because of the cold morning. All four tires are a few pounds low and I correct.
Back inside the vehicle, the indicator is still on! I get out to check the spare but, cannot because the valve stem is on top! And, my shirt is all dirty!
At home, I lower the spare and check/add air. Raise spare, put tools away. Now I know how to lower the spare.
Our basic Chevy vans at work let you know tire pressure in each of their four tires.
