TPMS light on, all tires >42 psi

[LB4Runner05]

Same thing happened to me on my 05. About 6 years ago the light came on and it was my spare. About 2 years ago it happened again but this time it was the actual sensor in the valve. I just let it go as the sensors were around 150 each. One important note; all of my tires had a slow leak so I put all new valves and it solved it. Good luck.

Nope, you can't adjust the sensor; we don't see it to often but every now and then we get one that instead of just dying completely it gives weird readings.

^Truth. Seen some give weird super high (262psi?) and low readings once in awhile. Sensor death is a strange thing...

It depends on how many sensors go bad. IF You do need sensors and you want to save some money. Search for something like this:

TPMS Sensor Pacific 4260733021

Pacific is the company that manufacturers our TPMS systems. So you might be able to just find some TPMS sensors that are basically the same as factory (minus Toyota badges) for a more affordable price. What I will warn you is to make sure that the FCC ID (the ID number that will be registered into the TPMS module) is a 7-Digit ID. I've run into this already where places like Tire Rack and/or Big-O, ect. have installed an 8-digit unit by accident (our newer vehicles can use an 8-digit ID or 7-digit ID) and they can't program it to the vehicle because the TPMS will only let them input a 7-Digit long ID string.

You could probably get 2 sensors replaced and programmed for $200, depending on how much the sensors and programming cost is (and again how many you need.)

Great Info! Came across this thread as my TPMS is flashing (for over a month now). Don't want to do the TPMS-delete mod, I like having everything work as the factory intended.

Toyota quoted me $220 for each sensor plus $180................... :lmao:

........and to think some folks actually pay that

I wanted to do some TPMS work on a couple sets of rims and didn’t want to deal with the dealer or tire shops… this tool came forum recommended, and will pay for itself in one use.

I don’t really NEED to keep this thing, but I like being able to monitor tire pressure from inside the truck. It is nice to have. Ill sure it will come in handy again sooner or later.

Cost about $100 for 4 programmable sensors. I'll be getting 10 for 2 sets of rims with spare tires. Planning on cloning the IDs so I can just swap tires without dealing with TPMS issues. (hopefully)

Several years ago my TPMS light went off ... checked my tire pressure and all the pressures were fine, so I figured at least one of my sensors had died (and the others were soon to follow based on age) and promptly did the bypass. Fast forward to a couple of weeks ago when I installed a new head unit with the Maestro RR w/T01 harness ... wasn’t expecting it, but was surprised to see that it still accurately reports the pressure in all of my tires. Has me wondering how the sensor can fail and still report the correct pressure?

Interesting.

TPMS are for people who neglect their cars. I've been driving for 36 years with vehicles that never had TPMS and I never once had a flat tire, EVER! Can TPMS be a value for certain situations, for example someone who hauls a trailer and has a slow leak? Perhaps. But for those who are car conscious, like most ppl on this forum, you don't need it. Inspect your car and check tire pressure regularly. I think there is a write-up to bypass the light if you choose to do so. I think they're expensive to replace.

I disagree with you on this, TPMS is a tool IMHO, I have been driving for over 45 years and as with you I take care of my rides...BUT a few months ago I drove 450 miles for a family reunion, I have a brand new set of Michelins on my T4R, I checked all the pressures in all 5 tires before leaving even though my TPMS is in working order, after driving for around 2 hours I stopped for a bathroom/breakfast break, again checked all the tires before hitting the highway again, about 2 hours later my TPMS light comes on, I stop and find my right rear tire is a bit low and I can hear it leaking, must of hit something on the road to punture a repairable but rapidly leaking hole in the tire, without the TPMS I wouldn't have known the tire was leaking until it got so low on air that the tire would of most likely need replacing, runnin a tire low on air at highways speed will seperate the plys a little and that tire wouldn't last as long as the rest, so the TPMS saved me on having to replace a $185 tire, but to each his own, I'm very old school, but IMHO the TPMS is not a baby sitter but was intended to do exactly what it did to save my tire and possibly prevented an accident if that tire got low enough to blow out from crusing at high speed with it losing air as fast as it was!

Sure, it's a convenience...but it's for a safety related issue.

Expensive, well, I buy Denso TPMS sensors on Amazon, cost about $40 ea. / $200 for a set of 5. Get them installed during your ten year tire change. If they last 10 years, that breaks down to $20/year..

"But for those who are car conscious, like most ppl on this forum," that's cheap insurance. If you have multiple drivers/multiple cars in a family, the cost really is not an issue.

My co-worker just got a text from her vehicle that a tire PSI was low, what parent would not want that App on their family members vehicle?

If you just need new TPMS sensors I would try checking eBay also. I got a full set of 5 from there for about $25-$30 a piece and they are Denso brand. Haven't had any issues.

I saw on Rockauto they sell Denso as well as AC Delcos. Question is: Does one normally get the "kit" (ring, washer and I know what else) that is sold separately?

The Denso sensors I get from Amazon, includes everything, though not all the parts are pictured.

Steel wheel sensors (spare wheel) use a different sensor, with a shorter stem.

Invaluable information right here! My TPMS light has been flashing for a few months now and driving me nuts. I won't do the "mod" b/c I'm a stickler for all things working as the factory intended. I've had my rig since 2010, so no doubt one/all of the sensors need to be replaced. Toyota quoted me a price of something like $80 each sensor plus $100 for programming. Do the math for 5 tires. Eff that.

Thanks Blackworks!

Did the "bypass" mod and my light was still coming on so I pulled the gauge cluster out and put a piece of electrical tape behind the logo, problem solved :lol:
