Go with 35 psi and see what happens. Or check the ture pressure info in the door or check the owner's manual. Their threshold could just be set high.

 

Set tire pressure to your desired cold pressure, then follow the TPWS initialization instructions in the manual to establish the base pressure the system works with, it's likely set too high, although 32psi cold is underinflated, it should be at least 33psi cold. I use 35psi, then the tires are never underinflated for the next month or so, depending on temps.

 

My 2007 Tacoma had a tps in the spare tire!

 

The correct pressure should be listed inside the doorjamb. Pump up the tires to that. Make sure the full size spare is correct too.

 

There's no full size spare in the Venza HV, there's no sensor in the temp spare.

 

If I had to guess I think the tires were over inflated and registered with that amount. So in other words, if they were registered with 35PSI , then I assume the light would go on. Dealers are known to inflate. I check my tire pressure and always have to adjust the following day. I also check every 30 days as well.

 

IIRC, the TPWS tolerance range is either 4 or 7 psi, when pressure drops beyond that amount below the initialized pressure, it illuminates the TPWS lamp.

 

thanks - I was assuming 30psi was normal. I'll inflate to 33 and see how it goes.

 

We have the Venza LE and the door said 33 PSI. The LE has 18 inch rims instead of 19 on XLE or Limited.

 

As shown in the manual, both 18" and 19" tire pressure specs are 33psi, spare is 60psi.

 

As stated Venza DOES NOT have full size spare and no TPMS in the donut.
Had similar issue. Set cold PSI to 33 then followed the TPMS registration process from manual. No further issue after that.
PS - Venza retains 2 sets of TPMS readings for those of us that use separate snows, so when I switched from summer to snows, the vehicle recognized the TPMS in the snows. Love that eature, and not having to go to dealer to register them.

 

Rolling friction might warm the tires some, but the engine or heater will not. You might have to let some air out in the spring when weather warms up. As it is, at 30 degrees, pump the tires up to the right psi before driving. TPMS will activate warning light when psi is + or - 7 degrees. That is low pressure or excess pressure. No full size spare- no worries about that then. The air we breathe is 80% nitrogen anyway, so don't worry that you don't have pure N2 to fill tires with.

 

correction; I said degrees, but I meant + or - 7PSI

 

I'm sorry if you have done this, but look in your driver door jamb for a sticker that is usually yellow. Usually. One of the stickers will list the tire pressures that you should use. The pressure on the tire is just their maximum rated pressure.

According to the Google, you should have 33 PSI in your tires and the generally accepted tolerance is 10% off pressure and you can run into tire wear and possibly traction issues.

It's normal for tires to lose pressure over time even when there are no punctures.

My advice is honestly, just put about 34 or 35 psi in all your tires and be done with the tire light instead of waiting and hoping the light will fix itself.

You're running tire pressure 10% low and it's not unsafe. You are, however wearing down the shoulders of your tires and losing a large amount of fuel economy, up to about 2 or 3%.

Cut and dry, It's wasteful. Please just air up your tires.

 

Hi, I also have a new Venza XLe, and I had a similar problem a few months ago. I know in the past my previous car would do this when it got cold. However, with my Venza it would stay on all the time. Finally I found a place in the manual where it talked about resetting the tire pressure sensor. I did that and have not had any more trouble. Good luck!

 

But my tire pressure sensor light came at about 32º a few weeks ago. It stays on for days. Even when it warms up and I click thru on the dash and it says the pressure is 30psi on all tires (so should be ok) the light stays on. I'm finding myself leaving the dash set to the tire pressure screen and just watching it while I drive!

Not sure if weather temperature would make that much of a difference on your tires pressure to make your TPMS lights go on. You mentioned 32F. It was -16C (3.2 F) this morning where I live (east coast of Canada) and my tire pressure was 10% lower than what it was inflated to, but no lights came on. A few minutes in and the pressure was up to normal.

Did you try resetting the TPMS like @Gabelle said on the post above mine?

 

I always inflate my tires a few lbs over. So if it calls for 33 I will set it at 35/36. When the cooler temps come or if I am driving up to Canada (in winter) I'll make sure I'm still at that 35/36.

Of course, in the spring I'll make sure to let some air out so they aren't above that 35/36 psi.

My tires have always last as long as the manufacturer states they should. I've never had premature wear.

 

1 PSI change for 10F change in temperature. So it it's 30F and the temp drops to -30F that's a 6 PSI drop cold and same goes for the opposite when it gets hotter. Simple math.

As stated a million times:
1 - Garage and outdoor temps can have a big difference adjust accordingly.
2 - Inflate to proper pressure cold.
3 - Inflate to door jamb pressure unless.
4 - Those with a "RESET" button: it's not a "RESET" it's a tire pressure threshold "SET" function.

 

Here was a weird anomoly:
Wife hit debris that slashed her tire (sudden loss of all pressure).
Service man put on the donut spare.
Because the deflated tire was in the rear, and came off the rear, could it still be sending a signal? The car displays 0 psi / check tire when safe for 2 days.

Two days later had DEALER replace the 1 tire with OEM. Got just one b/c the car is at only 5000 miles on the other tires.

DEALER could not get the TPS message to reset. DEALER gave car back to my wife with warning message still displayed. We both said "unacceptable" and took car back. DEALER had to spend 30-45 minutes with a computer attached to the car to get the TPS working properly (we think). Temperatures were a nominal 65'F in sunny California and we were at one of the nation's largest dealers. Which is why I call this an anomaly.
🤷🏻‍♂️

 

As long as the sensor is near the car it is likely to be read.

TPMS, not TPS.

 

Toyota changed the name of the tire pressure monitoring/ warning system, it used to be TPMS for many years, then changed it to TPWS. TPMS was used in the 2019 Rav4 manual.

 

Which is why I left the 4th character off. I didn't want to start an argument or debate.

 

It did the opposite... tire pressure system would suffice instead of TPS. It's fine.

 

Well, I stand corrected. I just re-read manual and see, as you say, both TPMS and TPWS. I was wrong.

 

I thought my tire pressure was fine because the Toyota app said it was “good” at 54-55 psi, until reading the threads on here. The app was correct, as checking each tire with a gauge showed the app was spot on. I lowered them to about 37-38 psi and the ride was significantly less bumpy. Kind of alarmed that the car was shipped with grossly overinflated tires, that the dealership didn’t adjust it before delivery, and that the app indicated such psi as “good”!

 

...Kind of alarmed that the car was shipped with grossly overinflated tires, that the dealership didn’t adjust it before delivery, and that the app indicated such psi as “good”!

They are all shipped with the tires at 55psi. It's SOP for all manufacturers to prevent flat spots from forming on the tires while the vehicle is anchored down during shipping.

It's supposed to be SOP for the Dealer to lower the pressure to 33psi before delivery, but this is commonly overlooked when vehicles are being sold right off the trailers.

 

High pressure set a factory for ocean shipping, so 50+ was good, and since all 4 were within acceptable range of each other, app says pressure is good. Dealer should have lowered pressure to 33psi when prep was done, but obviously they didn't. Tire pressure setting, shown on door jamb is 33psi.

 

I’ll lower it to 33-34 psi this weekend. I wasn’t at home when I adjusted it yesterday and was worried about accidentally lowering it too much without an air compressor nearby. Dropping from 54 psi to 38 psi also seems to have dropped my car down an inch or two as far as my vantage point driving!

 

deleted my comment (found the PSI option in app). Odd, why do we have a picture of what looks like a RAV4.

 

@Quesoso I'm confused. I see in your previous post-show that you have a 22 Venza XLE. Though I don't see this option in my app. Also saw that picture has a sunroof. Is this your app for your Venza? If so where is it in the app, please?

Maybe I can help. Open app; select "My Garage" drop down from top; then go down to "Maintenance". You should see ":Tire Pressure" as option there.
