So I made the plunge and bought some aftermarket wheels from Discount tire direct. Pictures to come after drop. Bolted them on and 5 days later I get TPMS System error and no pressure readings from any of the tires. The days prior to the error message the readings on the mid for my tires were not correct. Tried disconnecting the battery but error message still comes up. So I put my stock wheels back on and immediately it starts working again. Sounds like the TPMS sensors in my new wheels are either defective or werent turned on right? Talked to Discount tire direct and they havent heard of the problem before. They said the car should just recognize the new sensors and shouldnt have to reset anything. Which I agree. I had an 05RL last year with aftermarket rims and no problems. They ultimately suggested I go to a dealer and have them use a scan tool to diagnose what the problem is and may have to have the sensors reset. I put the new wheels back on and dropped the pressure way down to like 29. (Another possible way to kick start the sensors) Now my mid doesnt show an error message but Im back to it not displaying the correct pressure. Instead of 29-30 its reading 33-34 which is what my stock wheels were. I imagine it'll be just a matter of time before I get the error msg again. So before I drive 100 miles to the dealer anyone have any suggestions?

defconskylude

do you have two sets of TPMS or did you transfer the stock TPMS over to your new wheels?

saucy

I am interested in this as well. Just purchased aftermarket wheels and tires and would love to bypass this issue if possible. Sorry you are having the problem though. Keep us updated.

Two sets. Left the stock ones in the originals. Got new ones in the wheels from Discount tire direct.

defconskylude

so youre using non acura tpms sensors? maybe thats why its not working?

maybe you have to buy acura specific tpms for the 2nd gens?

Gabe15

iTrader: (1)

Correct. At $28 a piece I dont think these are Acura brand sensors. The OEM ones are $68.03 each at AcuraOEMparts.com.
Yeah maybe the 2nd gen TSX doesnt like non Acura TPMS sensors? Oh well, Im fairly patient so I'll get it figured out eventually.

09TSXTech

Drive for a few more miles on your new wheels, the TPMS only reads periodic basis which is why the TPMS still shows the old reading from stock rims.

BTW, is your car lowered ? Mine show the TPMS system error almost on a weekly basis, usually for a short while and goes off. That occurs on my stock 17" as well as 19" (with Acura TPMS sensors). The dealer reset the TPMS for me but warned me the error will come back on/off due to my car being lowered.

09TSXTech

If you want to save some dough, try the TPMS sensor for the RDX. Part # 42753-STK-A03, they sell for $23.17 and works with TSX system. Both RDX and TSX are made in Japan.

so ANY dropped car gets funky with TPMS? lets say stock rims and a 1" drop front and back

Gabe15

Not lowered yet. Got springs today. Going to rent a spring compressor and do that this weekend.

So heres a question. Defconskylude might know the answer. If I installed wheels with no TPMS sensors would I get an error right away or would it take 4-5 days to register that there were no sensors?

ed_423

whoa i did not know lowering the car would affect the tpms??

I don't buy it. I've never had TPMS problems with my OEM sensors. I've always been lowered.

Unless this is a CU2 only problem, the stealer is wrong. If you have error messages, there is something wrong with your car. It's not normal, whether you're raised or lowered.

No. A 1" difference in distance from the TPMS reader making a difference? Not in my opinion.

09TSXTech

I am only relaying what the dealer said to me. I personally doubt that 1" drop will affect the TPMS sensors, but then again, I am not an engineer (there may be an angle or distance requirement in receiving unit). It's not occurring on a daily basis, I can live with the occasional TPMS Error with either set of my wheels. Will keep an eye out on TSB on that.

And to answer Gabe15 question, when I first installed my 19" without TPMS, the warning light did not come on immediately but after 10 km of driving.

I understand, and am not criticizing you. Some stealers get on my nerves with their misinformation.

defconskylude

youd get the error right away. i just drive without my sensors and ignore the signal warning. ive gotten used to it

ed_423

it would drive me insane

KillerG

Holy crap that would drive me insane too!

Gabe15

iTrader: (1)

Yeah, I cant have any blinking lights. Thats the main reason I got rid of the RL. That thing tripped warning lights every other day.

defconskylude

i just press the down button to get rid of the tpms error. the only thing that remains on is 2 yellow warning icons. it doesnt blink continuously. that wouldve driven me insane

saucy

One question. This is a noob question though, BEWARE! Are the tpms sensors from stock wheels transferable? If so, will that defeat this problem? Or as long as the are Acura manufactured is that the fix for this? I am quite OCD even the non flashing warnings will make me punch an elderly in the throat.

Shotimer

I put on 19" legends on my car last year and i transfered the original TPMS from the Stock Wheels and put them on the legends. In the past year, i have not had any errors or incorrect readings.

Also, i will be installing Eibach Pro today so i should probably have an update on lowering the car causes an error or not.

Shotimer

also to add to my previous post, doesnt going from 17"stock to 19" rims move the TPMS locations about an inch any ways?

so my assumption is that 1" of movement doesnt cause any errors. but may be 19" rim and lowered car (about 2" movement) could make a difference? i really dont think so but i'll find out soon enough.

ed_423

haha im with you on that dude, even when i have low tirepressure light on it still bugs me, i go and put more air in the tire right away

Gabe15

bahh ha ha!

You can definitley swap out TPMS sensors but not 100% sure the stock ones I have will fit the aftermarket wheels I have. Are TPMS wheels all standardized? Once I make a trip to the dealer that will be one of my questions.

KillerG

i think the legends have acura/honda TPMS sensors in mind so if you get ronjon wheels you should be jelly

TrixieSX

I'm dropped on S-techs and 18" Legends. never had TPMS errors so far. moved my oem sensors to my legends

saucy

I ordered and waiting for 19" Axis Elites to arrive. I guess i will try to move tpms sensors over to them and see what happens. Thanks for all the help on this topic.

ed_423

when you move the old tpms to the new wheel, is there something you need to reset? i heard there are some parts you have to replace in order for the old tpms to worked? or do you simply transfer over and it will work?

defconskylude

take off your oem tpms sensors and just store them in your glovebox. it'll still read them even though theyre not mounted on the rims

I'm lowered and have no warning lights with either my winter rims or summer rims. I've got genuine OEM Acura sensors for the TSX. They are apparently self-learning. When I bought the sensor, I bought a "rebuild kit" also which is a few bucks and makes sure that the sensor sits flush against the rim so there are no leaks. You can do a search for it but I've posted about this in the past....apparently each time the sensors are torqued down the o-ring or little grommet thing deforms a bit so the rebuild kit is necessary each time you take off and put back on the sensor.

good one lol

tpms causes more problems than it solves

Just left a discount tire store 50 miles from home. They confirmed that none of the sensors were submitting a signal. They had to order a new set to install and if that doesn't work they will install the ones from the stock wheels. Frustrating yes, but so far every discount tire person I've talked to is determined to make it right. Which I find uncommon.

1. Lowering does not affect TPMS, PSI is PSI
2. RDX is not made in Japan, TPMS sensor is different as well, if it has the same part number, than you can use it
3. Acura TPMS resets every time you turn the ignition, this is why you can rotate your tires, and it will read the correct tire every time on the MID
4. Why would you try anything electrical not made by Acura? It obviously wasn't made by the system.
5. Make sure that the wheels you get can accept the Acura TPMS, based on the shape of the wheel, the sensor may not be able to sit flush

09TSXTech

1. PSI is PSi and KPA is KPA, however, the TPMS receiving unit in the wheel well may be affected by the change in the angle and distance of aftermarket rim as well as lowering springs change the swipe area of TPMS signal.

2. My mistake, RDX is made in Ohio, the TPMS sensor for both TSX and RDX are made by Pacific Industries, and quite a few members in the forum bought RDX 19" rim and the associated TPMS sensors work with TSX without problem.

3. When I put on my 19" rims without TPMS sensors, the car took close to 5 miles of driving before showing TPMS error.

4. Agreed

5. Well said, not all rims are TPMS compatible, remember, TPMS is mainly for North American vehicle due to Federal law requirement.

According to the dealer, aftermarket sensors won't work before being programmed to the tpms in the tsx. That's why the sensors from Discount Tire wouldn't work automatically after driving for a few minutes. I had to learn the hard way. I used the oem sensors and no issues.

Just giving you my experience. No matter what Discount Tire does, those sensors you got from them are not going to work without the dealer programming them.

Let me know though if they do find a way however and I hope it works out for you. Oh and my wheels are 20x8.5 so I doubt distance from the wheels to the car will affect this as noted by some on the thread.

2. I just put on TPMS sensors from an MDX with part number 42753-STK-A04, different part number from TSX TPMS sensors (42753-TL2-A51) and it works. I believe A02, A03 and A04 will work with the TSX. Got a set of 4 for 50 bucks off of eBay. Way better than 75 bucks a piece for the original TSX ones. No reprogramming needed either.

FIXED! Did the round trip again this afternoon. The culprit was incorrect TPMS sensors. The guy showed me the ones he took out and the ones he was putting in. Different part number and different color. Guess whoever installed the TPMS originally simply put the wrong ones in.

Summary. I do have aftermarket TPMS from Discount Tire Direct. They self learned after driving less than a mile. My Mid now displays the actual PSI in each tire. Fixed free of charge and treated professionally. Happy with the outcome.

Now If my garden hose would just unfreeze so I could wash this piece.

Hey, thanks for posting that information. That must be what happened in my case also.

This is awesome info! I just bought wheels and was thinking about having discounttire put them on former. I was debating on swapping the OE sensors or buying a second set. At this point I will just buy a second set from DT and roll on! Thanks for sharing this info guys!!
