So I have been trying to figure out what to do with my TPMS, I have aftermarket wheels and ordered the TPMS in the wheels but after a couple of drives my light came on. In 2011+ g's Infiniti took out the wire used to reset the TPMS system so a dealer visit is required. So my questions:

1. How many TPMS sensors will our system hold? It would be nice if it were 8 so I can have a set of summer/winter wheels.

2. If our system only hold 4 then a different solution is necessary, possibly something like this: DIY - TPMS Canister/Pipe Bomb - Club Lexus Forums

Has anyone "acutally" tried this? I have read a lot of people say the G needs to moving but this doesn't make sense to me as the sensors don't have accelerometers in them to sense the movement, the ECU would know and alert the TPMS system to check. So technically the pipe solution "should" work.

Thoughts?

 

Yes the vehicle needs to be moving as the sensors transmit in the 750 mz. range to an antenna and receiver module located behind the glove box
These TPMS sensors should be properly paired to each wheel.
If the proper signals are received the light turns off.

So, what would stop the idea of a pipe with the sensors in it from working? Just trying to understand what actually happens from a technical perspective not from the manual which is dumbed down for all.

I think I am going to try the pipe idea, what the hell I have nothing to loose the TPMS are already out of the old equipment.

 

Nothing would stop it other than not having TPMS sensors that would work and the, IMO, bad idea of having a canister of compressed air rolling around in your vehicle. Do a quick search and you'll find another thread on this topic as well. I think it was in the tires / wheels section.

 

I did search and my questions were not answered, no one actually did it, and no one could confirm the number of TPMS sensors our system can hold.

You could mount the canister in the trunk so it's not rolling around?

 

Placing your TPMS sensors in the trunk is a bad idea, and serves no purpose other than extinguishing the dash light. If you’re going to get into that sort of thing, i.e., bypassing safety devices, you might as well as disconnect your seat belts, remove your air bags and place them in your trunk as well. You'll have the safest trunk in town.

 

This was in the same thread, and seemed like a much easier solution

I just experienced the identical situation with new wheels. Local shop reset each sensor and it's been fine since. Should cost about $5 per corner. Go to any tire shop. No appointment necessary, because they just come out to your car with the OBDC jack and a wireless tool that wands each corner.

IDK if our ECU can handle two sets of sensors. Guess I'll find out before winter comes in November. If not, it's only $20 twice a year.


While I agree, the trunk "solution" is both clever and pointless at the same time, your analogy has no merit. Once again your brand of helpful comments has come around to spread snarky joy that only you seem to value. God only knows why.

Yawn.

 

I just put a small piece of electrical tape over my in dash TPMS light.

 

Another great solution. But what would you do if you had a slow leak pop up some hot day at 80mph? Without that light you could be rolling over six times before you realize you’ve had a blowout.

I can only suggest that on your way to the hospital ask someone to remove that piece of tape lest your insurance company denies your claim.

 

I think the TPMS can provide useful information to the driver, and critical information to a driver who isn't paying attention to their tires. But having one idiot light representing all four wheels is more annoying than helpful, in the context of how often it's necessary. Lots of newer cars show individual wheels, and the pressure on each wheel. THAT would be nice. Wish I had that on my G.

Anyway... soapbox blah blah blah.

OP, please post up if you find in your research whether or not our car's ECU retains more than one set of Sensors. I haven't found that info yet.

 

I don't have TPMS on my 20s, I realize the risks but I've driven 35 yrs the old fashioned way and it's been OK. I always check my tires prior to every long trip and weekly, but low profile tires are deceiving so I do stay pretty alert w/ them.

 

Now I don’t really want to go over this adnauseam after all the past posts on this subject, but here’s one last try at my points you’ve missed:

1. You can drive a lifetime and never get a flat, certainly not one stemming from a slow leak. But underinflated tires have caused deaths, which is the reason we have a TPMS requirement in the first place.

2. You can check your tires prior to any trip, but a pesky nail can cause a problem in the first mile driven, and you’ll never know that without TPMS. And as I said before, unless you’re willing to pull over every half-hour to check all four tires with a gauge (you cannot see that a tire is down to let’s say 28 psi), TPMS is there to help you.

3. I have bested your 35 years, having driven over 60 years with most of it without today’s safety devices (No seat belts, air bags, padded dashes, collapsible steering columns, turn signals (they were a dealer installed option in most cars in the early fifties), dual brake lines, pop-out windshields, side lighting and of course TPMS) and never had a serious mishap. But it doesn’t mean these devices were unnecessary; it just means I was lucky.

Now I’m sure you’ll agree that a good driver doesn’t depend on luck. But dismantling a safety device that came with the car, IMO is going in that direction.

 

This guy.

 

Chekov, I know you speak from concerns for safety, and I can't deny the benefits of a TPMS system. I completely understand a low tire can happen any time rubber meets the road and I will be restoring my TPMS sometime down the road. There's a lot of hazards in day to day living & driving so minimizing them is a good plan, your point(s) are taken.
