TPMS Issue with 2019 Honda Odyssey

We have MY 18 Touring.

Tried using aftermarket TPMS when we purchased winter tires. Warning light kept coming up. Garage tried flashing the ECU, to no avail. Went thru 2 sets of TPMS (different brands).

After 3 trips to the garage, they finally decided to call a Honda Dealership and Honda said only OEM TPMS would work. Haven't had a problem since.

damn. why would simply tire sell me aftermarket ones then. any idea how much the oem TPMS cost? I paid 70 each (or 280 each) plus tax for the aftermarket oem sensors. i also find it weird that it did work last year without any issues.

I wanted to reuse my old winter tires on my 2020 Acura RDX ( a Honda product). The tire shop also wanted to install aftermarket sensors, and charge me a programming fee as well. I wanted to ensure that I would not have the type of problems you have, so I asked if they would install OEM Honda sensors if I purchased them, and they agreed. I bought them at the Acura dealer for $52.09 each, complete with all the required mounting hardware, Each of them was in a plastic bag with the Honda name. As expected, they started reporting to the car automatically after 5-10 minutes of driving.

wow. I feel ripped off. I paid more for the aftermarket ones than the oem ones.

My wife drives the van and says she hits a small bump and the TPMS problem light comes on and it no longer detects the tire pressure. She drove the car for about 30 minutes and the warning light remains.

Let me get this straight...

TPMS sensors were working perfectly fine for a while.
Then, minivan hit a bump or pothole, and the light came on.

Did you check the pressure in your tires? Is it possible the pressure is low, therefore the light went on?

The simpler solution should be attempted first.

I know my partners description of small bump/pot hole.

I personally would not classify it as small.

As the above post check tire pressure and bent slow leak rim.

Cheers!

to be clear, the TPMS is not even reading the tire pressure. I.e. there was reading in all four tires prior to the bump. Then she hits the bump and now there's no reading. The light wasn't a low pressure light. it was a TPMS Problem light.

I have a 2017 RDX with TPMS.

I bought an older set of RDX wheels with Honda sensors for winter use.

It takes a few minutes but the computer automatically calibrates to the new sensors.

It's ridiculous you should have to have new TPMS sensors reprogrammed in the first place. Anytime you put in new sensors, it should be exactly what you mentioned above. It should be a non-issue.

OEM TPMS from Honda were 58.50+tx each.

Any way you can turn TPMS off? *shrugs*
I don't have TPMS on my car.

I think i read that some OEM sensors don't work with some aftermarket wheels or vice versa.

Maybe that's why Simply sold you aftermarket ones?

I would go back to Simply and see if they will warranty the sensors

I just had one OEM Honda sensor replaced and I think the $58.50 is correct.

Oh, I see.
Do you have the TPMS system that shows each tire's individual pressure on the dash? I imagine you do.

Do you see an obvious problem with the rim / TPMS ? Do they look damaged?
Is the tire losing pressure?

Running over a pothole shouldn't cause the TPMS to malfunction...

Yes, it's a direct TPMS system so it shows the tire pressure for each individual tire. Rims and tires look fine. Pressure looks fine. I'm just confused because it was fine all winter last year. It was also fine when I installed it this past Friday. Wife hit a bump and now it doesn't work. I suspect that it's because it's not OEM TPMS sensors. I'm really upset since SimplyTire charged me more than the OEM ones. I've e-mailed Allen at simplytires and hoping he'll get back to me. But this time of year is really busy and I can see them just ignoring an old customer and dealing with the new customers that actually bring in revenue for them.

Is there anyway to reset the TPMS without an ECU reader?

Every TPMS system is different.

Basic systems have 1 receiver and 4 transmitters. The receiver has the 4 sensor RFID's programmed into it, and if any transmistter reads low pressure, then the warning light comes on. Some systems can display the pressure of each corner. However, when the tires are rotated (along with the sensors), the receiver must be reprogrammed because the sensors are no longer in the correct position. Some systems have 3 antennas and are able to triangulate the transmitter signals so that the car automatically recognizes which sensor is in which corner.

Post #9 is surprising to me. Because that 2nd set of wheels would have a set of sensors with 4 new RFID's which are different that what the car is programmed for. I've never heard of a system that can automatically recognize new RFID's. Perhaps that is an evolution of the triangulated system I mentioned.

That leads me to the higher cost of OP's aftermarket sensors. Some sensors are known as "cloneable". Meaning that you can copy, or clone, the 4 original RFID's from the old sensors and program them to the new sensors. This means you now have 2 sets of wheels, both with the same set of 4 RFID numbers. So when you swap between sets of wheels, the TPMS system always recognizes the sensors. So there's no errors or reprogramming necessary. OEM sensors cannot do this. New sensors would have 4 new, different RFID's and so the receiver would need to be reprogrammed every time the wheels are swapped.

I bought 4 tpms sensors from Acura to costco to install onto my Costco rims turns out they are not compatible. Something about the oem sensors leaking air. Costco made things right though by refunding me the difference. Pretty sure for Honda and Acura the system relearn the sensors so there is no need to reprogram the system. However because you are using aftermarket sensors your sensors need to clone the OEM's at least that's my theory. Hitting the bump must have bugged out one of the sensors causing an error.

Your Odyssey should have, in the settings, the ability to reset the TPMS system. There also might be a TPMS button on the left side of the dash where the other saftey system buttons are.

As you are aware, you overpaid for aftermarket sensors. The Honda ones are $55 ish plus tax with the nuts and washers.

sounds like a sensor is damaged, or the bump was big enough to throw the whole system off.

1. Check for damaged sensors, leaks and damage on the tire
2. Check the vehicle settings and recalibrate the tpms system manually
3. reset the electrical system by disconnecting the battery and reconnecting after a minute or so. Make sure you have a radio code and navi code on hand.
4. take the vehicle in for diagnosis if none of the above works. I would also take the same opportunity to remove the aftermarket sensors and install Honda ones. If the tire has to come apart anyway for diag.

Good Luck.

thanks for this info.

for #1, i can't tell whether the sensors are damaged but there are no leaks and no damage to the tires.
for #2, surprisingly there's no way to recalibrate the system manually. I've checked the left side of the dash where there's lane assist, etc. and there's no button. the console also doesn't have a tpms reset or recalibration button. however, i've seen some videos of Honda cars that do. I believe those are indirect TPMS or my model (EX) just doesn't have it (the odyssey has direct TPMS). I've also of course checked the owner's manual.
for #3, this is my next plan. I plan on disconnecting the battery. Unfortunately, the battery is a bit difficult to reach as I have to remove a couple of covers but i have access to the positive terminal without having to remove the covers. Can I just remove the positive terminal and wait a couple of minutes and reconnect? or do i have to do something in between (like try to start the car)?
for #4, that's my last option. to take it back to simply tire. However, this is probably the busiest time of their year and they're probably just ignoring my e-mail in which case I might need to bring it to the dealer and get them to install the oem ones.

See post #16 from @derass explaining different types of sensors. If they sold you clonable sensors then you “overpaid” in the short term but will save in the long term as you won’t need to pay for the system to be reprogrammed at every swap. So before complaining to Simply Tire you should first find out if they sold you the clonable sensors or not.

Have a look at this explanation for how to recalibrate your system yourself:
