Hello guys

I have an 07 G35 coupe and I always get the tire pressure light on on my dashboard. I took my car to the local Infiniti dealership and all the tire sensors are fine (all tires temp. approximately 32), I really do not know what the issue is. But I really hate having this light on my dashboard.

Is there anyway you can clear it manually even if it will come back in a few days or weeks. Is there any cheap tool that I can buy to clear this on?

 

Do you have an iPhone/android?

The ELM 327 (or similar #) OBD2 wifi dongle is 15$ and sends engine trouble codes directly to your phone with the use of a third party app called torque or dashcommand. It can also send other interesting data to your phone!

 

an iPhone. But does it clear the TPMS light?

 

Yes, there is a way

Under the driver's side dash, is a small connector that you ground to the chassis to trigger the code-displaying function of the TPMS system, or to activate the relearn process.

So yes, it is possible to troubleshoot and reset the sensors, however it's not a well documented process.

The malfunction codes are on page 23

The G37 procedure works for the G35, but refer to the codes above

There is a tool, but you don't need it.

basically you hook it to a chassis ground, and the test plug, and pull the trigger to ground it. You can do the same with a peice of wire, but the tool does offer convience.

I have the tool. and have reset my sensors twice with this method, as well as troubleshot that my rear left sensor battery was failing.

Helpful system, but it takes a little work to figure it out. Not as easy as plugging in a code reader

 

Air up the tires and drive it for a few miles.

How do they know the sensors are fine? Did they scan them? If the light is on, either a sensor is broken, a battery is dead, or you got new sensors and didn't sync them up. The dealer should be able to sync them up or any tire shop. The DIY they mentioned does work but it is irritating to do.

 

I have a very similar issue. Tire light always comes on after about a 30 min, shuts off when restarting the car to repeat again.

All sensors output fine, pressure is good, and tire shop reset the CPU several time. More of an annoyance I've dealt with these past couple years.

 

Mine came on the other day.

I checked my tires. One was at 30 psi and the others had at least 32 psi.

I inflated the low one up to 32 psi and drove a few days and the TPMS light stayed on.

I inflated all 4 to 35 psi 4 days ago and the TPMS light is still on.

I have never had a TPMS that just didn't go off when tires are properly inflated.

Nice safety feature that I wonder if it works now?

How to get the TPMS light off?

 

Read above... Mustang gave out a very well structured and guided solution for you.

Do you need a silver spoon to be fed with?

 

This is such a cool and helpful forum, usually.

It's people like you that make it complete.

Surely paper clips and grounding circuit with exact amount of air in each tire is not the only way?
Way to go Infinity, another bright idea.

Maybe somebody has the answer?

 

He could have been more tactful, but his answer was helpful. The link shows you a way to reset them manually. Or your battery/sensor is on the way out. Normally people say search but you don't even have to, just click the link.

Or any tire shop can do it. Not as convenient as say hitting reset toms on my bmw I drive, but the manual way does work.

 

Had the same issue. Find out which one is the faulty sensor and replace it with a new one or replace all four at once. Re sync and Problem fixed!

 

Unfortunately you need to buy a consult 2 computer (A handheld with Osiris similar controls). These cost 500$+. There is also some aftermarket copy of this, but it is still 300$+ and you have to take the time to find it.

You can also just remove the stock TPMS system as it is primitive and go with a more accurate aftermarket system that could take place of your ash tray.

If the light blinks before becoming steady, it usually means the battery in one (or more) of the actual wheel sensors is dying. The blinking first technically means some kind of malfunction, like not communicating with a sensor. Mine does the same thing, blinks for a bit > becomes steady > then goes out. I'll replace the sensors next time I'm due for new tires.


Yes, before someone discovered this basic DIY sensor programming, we used to have to PAY the dealership to program them with their fancy tools. So your options are have the dealership program them (for a fee), or use this rudimentary procedure and do it yourself for free.
