Man I hate the fact all vehicles have to have this system now. It will be nothing but problems and added expense once the vehicle ages. I'll keep an eye on my tires myself thank you very much. (I understand the legality aspects as to why manufacturers have to use it unfortunately)

I know with both my 2008 Ody LX and my 2008 Hyundai Santa Fe , I'll occasionally get the low tire pressure icon during REAL cold weather (the little tire cross-section icon that looks like a "U"), but luckily I've never gotten the 'general system failure' TPMS light in the Ody until recently.

Based on what I read I figured this would require a $$$ dealer reset, but it went out by itself the AM! Lovin' it.

It took about a week, so for other owners, don't despair! It just *might* go away by itself!

Are you sure the bulb didn't burn out ?

There are 2 separate issues:

1. Actual low pressure: COLD weather decreases tire pressure so the warning may be real.
Always check with an independent tire pressure gauge.

2. Swapping winter vs summer tires: If the TPMS ECU sees "strange IDs from the 4 wheel sensors", it registers a different message, basically it reads it as "system malfunction" because it cannot read any "known" IDs from the wheels.

Mine came on in my 08 EXL about a month ago, so I went to the dealer. The service advisor told me it was either a weak battery that could cause the TPMS computer to malfunction or it was the computer itself. They put in a new battery and reset the code,and for about a week all was fine until it came on again, so back to the dealer for a new computer and it's been fine since. Battery and computer were covered under warranty also.

I hear you, but:

1) It wasn't the low tire pressure warning, it was the general "TPMS" light. Like I say, we've had the low tire press warning during extreme cold weather, wasn't real and the tire icon went out by itself. We never had the TPMS light stay on before this incident.

2) There was no tire/wheel swappage.


The light is still out! and yes, it still lights up during startup self-diagnostics.D

I sometimes get the "TPMS" light (not the low tire pressure warning) while in the highway.

Usually resets itself on the way back.

I thought at first it was the sensors but its also happening on the second set of sensors for my winters.

Most of the time it is off so no biggie. My bro-in-law has a Pilot and he says the same thing. He just ignores it.

My understanding is that you need to pump the tires 3PSI over stated pressure on the label and give it some time to reset itself.
