OEM TPMS Sensors

I was able to use my 16" alloy TPMS on my new 17" alloy wheels with no issues

 

Thanks for the input @imom . I have the following wheels on my truck now.


ALLOY WHEEL; 17 X 7.5; 5 SPOKES; 6 LUG; 5.5 INCH BP;

According to Discount Tire & NTB Tire, the sensors I have posted for sale from the SR5 16" Alloy (paint matched) wheels will not work with these 17" wheels. Is it possible both shops were incorrect based on your information? I don't mind trying another shop and/or location to confirm one more time but I took their word after both places both told me the same. I should probably stop by the dealership and see what they say.

 

It appears that these TPMS modules have a door to replace the battery. That would save tons on purchasing new TPMS and programming costs, if true.

Do you know if those doors can be opened?

 

There's a bit of confusing information on most topics in forums so research for yourself what I say to you...but "Valve stems on steel wheel sensors are at a 40 degree angle and alloys are at 20 degrees" I bought TPMS for alloy wheels and they work. The steel TPMS have a steeper angle so when you install them onto alloy wheels... they can potentially break easily when installing and removing the tire from the wheel. So some folks spin the TPMS sensor 180 degrees... but it can be an issue still I don't know that part. I have steel wheels since my truck is basic regular cab. When I bought new alloy wheels (non Toyota)... I just bought Toyota alloy TPMS and they worked well...no issues.

Now regarding reusing your old ones...perhaps the two tire shop didn't want to reuse old so they don't have to deal with removing it again if you had problems later or they wanted to make more money. TPMS sensors should last some time...how many years? Could be 5 to 10 years...I'm guessing range here. If the tire shop say they don't fit...ask why... what's the angle... because it sounds like they are bullshitting you.

Good luck.

Oh...I would say stick with the trouble of using TPMS. Aftermarket radios can read the OBDII so it can tell you real time the tire pressure. I was able to read my tire pressure through OBDII and think it's a neat feature to have when I install a radio that can read it...then I know if my tire pressure is low or not...good for MPG.

 

Very much appreciate the detailed response. I'm going to try another shop first and see what they say and follow your advise in asking "why they don't fit/work?" My previous wheels were indeed alloy so that shouldn't be an issue.

As for the aftermarket radio able to read tire pressure, I'm going to look into this. I have a pioneer sph da-120 appradio. That would be fantastic to have on screen readings.

Yes they can be opened to replace the battery

 

I haven't tried their radios, but Kenwood and Pioneer both advertise iDatalink - Maestro. You buy a module that plugs from the OBD port to the radio and then it provides and GUI that gives you control and information of what you can get from your factory system and probably more. I can't verify this as I have not upgrade my radio yet...I plan to you, but from what I research...this is the route and from using SW to read the OBD, I can see the tire pressure real time..so I can't see why you can't see this information real time on an aftermarket radio that supports Maestro interface.

Replaceable batteries is the more practical (but less profiteering for Toyota - and other mfgr's) way to go.

However, you still either need a very expensive, purpose-specific piece of electronic equipment to mate them to the computer or you have to pay a shop to do it.

Before this truck, I monitored my own tires since 1973, when I got my driver's license. Just because some people are too lazy (or stupid) to do it, doesn't mean I'm willing to foot a very expensive bill just to have what is at best, a convenience, and at worst (usually) a pain in the ass.

DISABLED. YAY.

 

Not true. If the batteries are replaced, the same TPMS module with the same ID code is still recognized by the ECU without any additional programming.

 

Very interested! Will you take $80? PM sent.

 

Can someone please confirm the OEM coin cell battery size in the TPMS for 2nd GEN Tacoma. I would like to just buy 4 batteries and take them with me to Americas tire so they wont have any excuse why they cant fix mine. I have had a constant blinking low tire symbol for about a month now because after 10+ yrs my sensors finally died. Could be 1 or all 5 batteries for all know. Any battery info would be awesome. Thanks.

 

They won't replace the batteries for you. In theory, you can crack the case and replace the batteries, but I doubt any shop will do it and guarantee the work. Even if they can replace it... it wouldn't make sense for them since if it fails...they have to crack open the tire and replace the failed TPMS. Your truck tpms has gone above the life expectany... it's between 5 to 10 years. If you don't want TPMS, disable it (various methods). If you want it replaced...if the tires are old...wait until you get new tires and buy some OEM online for less than the dealer or tire places charge. It's your best route. If you want to replace the batteries...you can, but you have to crack open the plastic and do it yourself and make sure the cover goes back and then take a chance they will work. Not worth the effort vs $100 to $200 new for the set.

 

Ok, so I ended picking up 5 new Denso Part#:

$38 550-0103 TPMS 315-MHZ Sensor for Toyota/Lexus with Factory Alloy Wheel Options. (THIS SENSOR MUST BE PROGRAMMED BEFORE USE), Black

550-0103 TPMS for $30 ea plus $3 shipping from AutoPartsKart for a total of $153. Now from what I understand Costco or Americas Tire should be able to install them for about $15 ea. Hopefully thats it.

 

Long as you buy the right one for your type of wheel...alloy or steel...then yes... they have a device that can access the OBD and program the TPMS ID to the truck and that will fix it. If your tires are newer than do it now, but I would wait if they are getting old and have them do it all same time...otherwise yeah, it's about $15 a wheel to dismount and mount tire. I had America's tire do mine.

 

Been using the 16" trd OR sensors in the TRD 17" sport rims for years and have had them on procomp wheels too. The guys at the shop is on rocks

 

Are these still available? I might need 1-2.

 

I hate to be a buzzkill, but the sensors you are selling are for the steel wheels. Notice the steep 40 degree stem angle. This explains why both of those shops wouldn't install them in your 17" trd alloys. I can't explain why they supposedly came out of the 16" sr5 alloys, but these are not the 20 degree alloy tpms.

 

The steel 16" wheel sensors will work in the 16" allow wheels. You have to rotate them 90 degrees. I've been using them for years over a number of sets of tires. The only downside is that you have to be careful when dismounting the tire because the body of the sensor is closer to the rim. The sensors for sale here could have been taken from steel wheels and used in alloy wheels, unless the OP knows the history for sure.

 

You are right...I should have check the pictures for the OP but pmv-108j are 40 degrees... his original wheels are most likely steel wheels or he bought the wheels from someone. I doubt the factory would screw up like that...but there's a chance.

I think you meant rotate 180 degrees.... as I mentioned in the posts earlier. Just a comment, but if your tpms sensors are 7 years or older...I would replace them unless you go through tires within a year or two...waste of money to use old sensors and then the batteries die or go bad and have to replace them.

 

Yes, sorry, 180 degrees!
