Looking for Aftermarket TPMS Sensors for EX35

[dividedhighw]

Hey Folks! A few questions related to TPMS Sensors ...

Since today is the last day of summer , I've begun looking in earnest for winter wheels and tires. So along these lines, I was wondering where (if anywhere) compatible TPMS sensors could be purchased, or if I would have to suck it up and buy them from the dealer?

Also, I'm led to believe that CONSULT programming is required to re-register the sensors, so it's back to the dealer twice a year, for about $100 each time ... is that TRUE?!?!

If so, I haven't ruled out the possibility that I'll just do without the sensors, in which case I'd like to pull the warning bulb. Does anyone know how to do this, or how hard it would be to do this?

BTW, if anyone is wondering about TPMS, there's a great write-up in the Rogue forum here.

Thanks for any info you can provide!David

dividedhighw, I am not sure where the sensor are on the Ex35 but i am aware that some newer tpms are not valve stem systems they will actually calculate the overall diameter of the wheel, example newer BMW's use this due to problems with the old valve stem systems. I am not sure if this is the case in the EX35 but i would assume that the tech would follow and since people and factory upgrade wheels and tires are not really standard i would see more of this type of system in place. I also suspect that the reason the spare is not monitored is due to this system and when applied to vehicle it does not meet the height and width calculations that are done.

what do you think.. i looked through manual and did not see any reference to sensor in tire.

Hey David,

I really don't think that aftermarket is the way to go if there are even sensors out there.

Your best bet is to buy the sensors and take them too the dealer. Depending on what you are getting for tires and wheels and how long you plan to keep the vehicle it may be worth the few hundred buck up front, snow tires usually last a few seasons.

It may be easier to just buy winter tires in your size to save money on rims. The newer Infiniti wheels take road debris and salt in stride, much better than their old ones. Most factory wheel that Infiniti uses now are made by Enkei.

It is true that the TPMS system needs to be registered using Consult III and the TPMS tool. I do not think removing the bulb is possible or advisable, but it's possible if that is what you want to do.

If you have a full size spare there is a sensor in that. So you may be able to get away with three.

Hi,

EX35 uses valve stem style.Its part number is 40700-JK00B.They are not really easy to find, since they are new for 08.Also it will cost you about $550 for set of 4, w/o installation.

Yes, you are right.You can register 1 set at a time.So, you have to re-register them twice a year.

Well, I've been using summer wheels without sensor.After few days, the warning light doesn't bother me at all...It's all up to you...

dividedhighwSome after market stuff out there.Take a look here...http://www.tirerack.com/access...stems

But I'm in agreement with others who have posted...1. Go with Infiniti TPMS = Expensive2. Go after market = Less expensive but not OEM integrated3. Stay with factory rims and mount and umount as the seasons change = Expensive4. No sensors and just deal with the idiot light

[dividedhighw]

Thanks y'all for your great info and comments ... VERY much appreciated!

Still not totally decided, but I'm leaning towards just tolerating the idiot light. After all, I've driven for 3 decades without TPMS and am in the habit of regularly checking my tire pressures anyway.

Cheers,David

Just leave the original tires and rims w/ sensor in your garage. Make sure you you clean everything first, then store each wheels/tires in a black lawn plastic bag and seal it. If I`m not mistaken, there is a certain miles the TPMS light will light up when it doesn`t receive a signal from each sensor. I believe 25miles driving the car with winter rims (no TPMS sensor) will trigger the warning light.When you park your car in a garage, your car will sense the sensors from your original rims (w/ TPMS sensors) and reset your warning light. The next day you have another 25 miles free off warning light. We`ll this info came from RAV4 forum, hopes this applies to the ex35.

One more option. If that light bothers you so much this is your last resort

[dividedhighw]

Thanks for the idea AWGD8. This might work, but I was under the impression that once a warning was triggered, the sensors would only reset while the vehicle was in motion (driven for 5 min at 16 mph or more).

Edit: My point was that sitting in the garage next to the summer wheels with the registered sensors would not reset it (unless you put it on the dyno in your garage!)

[zozoka1212]

Dave you are right. It is something like that. Few minutes driving to reset it. Not sure how long it takes to trigger the sensor tho. If it is more then your daily commute then you are ok. Till you have to take a longer trip. I would say our sensor is a littlebit more advanced than that.

The best way to go is one set without sensor. Most likely the winter set. Since they are on " only" 3-4 months.

Not sure if the G and EX are the same but some people disconected the tire sensor light. Here is a picture where the conector is on the G. Check your EX you never know.

Hope this helps.

[dividedhighw]

Yes, pulling the connection to the warning light (rather than the bulb itself), would be MUCH easier ... good idea!!! (I'll have to look into that.)

Cheers,David

Can I aske a point of clarification on this rather old tread.

I understanding having to repair the TPMS if we have 8 of them (4 on summer and 4 on snow rims). But can any mechanic shop do this or is this tool proprietary to Inifiti? Thanks

As mentioned above you need Consult III Nissan diag software (system). I also think you need a tire pressure sensor registration tool (I am not a tech but I think you need this tool). The activator/registration tool sends a radio signal to the pressure sensor telling it to start broadcasting its unique sensor ID (for a fixed number of seconds). The Consult III is used to assign/register the sensor IDs for each tire position on the car (Left Front, Right front, etc.). You can buy both of these tools so an independent shop could get a Consult system but I am not sure about the Nissan software. An aftermarket registration activation tool should be available for under $200 though.

With my 05 Corvette all you needed was the sensor registration tool to change sensor registration. You could put the monitoring system in learn mode by turning on the ignition and pushing two buttons on the key fob at the same time. The horn would beep then you would start with the left front tire and transmit the registration signal to the sensor by hold the tool against the tire sidewall next to the tire pressure sensor. When the monitoring system received the registration signal the horn would beep. When you registered the last tire (working clock wise) the horn would beep twice and the monitoring system would drop out of registration mode. Pretty simple process once you had worked through it one time.

Ahh simpler vehicles....I know my buddys 2008 Expedition was something similar that that and you use a magnet to trigger the sensors. It takes 5 minutes and has the same lack of display that the EX does.

Two years later there is finally some aftermarket support.

You know only six months ago we got a new tool in the mail at work.

It is kinda pricey but with the new software update it runs check engine lights and checks the signal strength of iKeys. That might not be practical for everyone but, if you rent it to others it might pay for itself eventually. But people really hate paying to have their tire sensors fixed. hahaha.

I don't know if this works but the companies website says it works with all known sensors.

I might actually get one of these some day.

[jmess]

The Quickset tool from the TireRack looks reasonable if it works for the EX. I would assume the sensors IDs are printed on the new sensors? I don't recall if my GM TPS had the ID numbers on them.

For those not following this thread closely, If you have the sensor IDs you don't need a registration tool to trigger the sensors to transmit their IDs.

Thanks Steve.

[SteveTheTech]

The sensor id is stored on the integrated circuit inside the sensor and as far as I know there is nowhere on the sensor unit itself. You cannot "read" or "write" these numbers per say, it is all code.

The older GMs used sensors belted to the wheels. My favorite were the Eagle F1 EMT tires that came stock on them for a while. Worst tire to mount ever!

Last question for me on our Infiniti's TPMS. Is there any damage done by driving without TPMS to the TPMS system or any other lost of function to the vehicle security systems? Will the stability control, etc... work as normal without TPMS?

I am considering running winter wheels without them.

Thanks

My understanding is that everything works as it should. You will only be faced with the "flat tire" icon, and that doesn't take long to over look.

I can't see any damage being done, as I purchased my wheels and tires directly from the dealer at the same time as I got the car. I seriously doubt the dealer would supply something that would cause loss of function of the vehicle safety systems.

I think you will find that nearly all the members of this forum who have a dedicated set of winter wheels are running them without TPMS. It's just not worth the hassle or expense.
