Hey guys, I'm new to this forum and I have a question regarding my newly installed rims. Perhaps I will drop by our new member area and say hi to everybody =D

I purchased a new set of aftermarket wheels by FastCo and had them installed on my OE Summer/All-Season set of tires and at first the TPMS light were on every time I drive but now it's been taken cared of.

The issue at hand still is: while the TPMS warning light is off already, whenever I check for Tire Pressure values on the dash there's always nothing to display... I took the issue to the shop where I had them installed and corrected the previous warning light problem and they managed to get everything back to normal by pressing the TPMS reset button at the bottom of steering wheel. However the problem persisted and again there are no values of tire pressure... Any ideas why?


Thanks.

you said that they reinstalled your oe tires, but did they transfer the sensors as well?

Hey, thanks for helping out.

What I meant was, I purchased a new set of aftermarket TPMS and slapped them on the aftermarket winter wheels after programming them from signals straight from my OE set. There are no warning light on my dash, but there are also no values displayed on dash on the new TPMS signals... I'm just wondering why this is happening.

depending on what aftermarket company you got them from, maybe they weren't programmed correctly or different codes? just a shot in the dark

This happened to me as well. I was told by my dealer that some aftermarket sensors are not able to send the pressure to the computer but the car will still warn you if the pressure is low. Which is why you no longer get the flashing light.

So I wonder which aftermarket tpms sensors are "fully" compatible with the 3IS?
Which make and models???

Why didn't the OP swap the original OEM tpms sesnsors from the OEM alloys to the aftermarket alloys?
Sometimes the OEM sensors don't fit on certain aftermarket alloys.

vftoronto

Hmm thanks for the response, I guess it is now safe to believe it's the aftermarket TPMS' fault then.

I work at a body shop where we sometimes work on tires too. We tried this method but sometimes OEM sensors get damaged so that's why I bought a set of aftermarkets.

Well as long as the warning light isn't on, I guess it's still ok lol.

vftoronto

Thanks for the advice.

So does removing the OEM tpms sensor from the OEM wheels occasionally cause damage to the tpms?
If so, I'll have to purchase genuine OEM tpms for my aftermarket wheels.

Also, does anyone know if the OEM tpms last forever, particularly the battery life, and is the battery replaceable, or is the OEM tpms a disposable unit, and another genuine OEM tpms must be purchased when the battery gets flat?

LexRuger

If the wheel shop knows what they're doing, they shouldn't get damaged but it can happen. Especially with low profile tires.

I think they're supposed to last 5 years.

I think they're disposable.

peteharvey

If so, then when we get aftermarket wheels, an expert is less likely to damage the genuine tpms on swap over, and in any case, the tpms is a single use disposable unit that must be replaced in 5 years anyway, so may as well swap over, rather than purchase another set of genuine tpms sensors, while the original set of tpms single use disposable tpms sensors get flat batteries and must be disposed of anyway...

Hi vftoronto,

I have experienced the same issue. Just wondering what aftermarket TPMS sensors that you have? EZ sensors?

wsabichris

i'm actually getting my wheels drilled this week to fit the bolt and my guy ordered new TPMS from tire rack. Hopefully it all goes well. I'll keep you guys updated.

If you ever have TPMS issues, you can always take the car to Lexus and have them reprogram the sensors. I had an issue with my sensors and the dealership took care of it.
