My G is the first vehicle I've owned that uses a TPMS. How do I buy sensors? Do I just buy whichever, or is there a specific sensor I need to get? Reason why I ask is because when I just type TPMS sensor into Amazon, the first couple results come up as "GM". So is there a sensor specifically for Infiniti?

 

Yes, you will need the correct sensors for your specific model & year. Not sure which online sites are best, but there are some that are significantly cheaper than the OEM sets.

 

Should be Infiniti part number: 40700-1LA0E.

Lots of alternatives though. There are "multi-fit" tpms sensors that have to be programmed for your car, as well as direct fit items.

 

Are you guys running OEM sensors, or aftermarket? I found this VDO REDI-Sensor for about $50 each, which will cost me $200 total for an entire set. Then I have to bring my wheels to my local tire shop/the dealer to get the sensors relearned which will probably add on another $100.

So I'm basically paying ~$300 to monitor my tire pressure? I can monitor my tire pressure myself for free >.< What if I decide to skip the TPMS and just regularly check up on my tire pressure? Are there any cons to that?

 

The only downside is a TPMS light on the dash... Many people who switch to winter tires quickly learn to not notice the yellow light. (Well, maybe it was just me)

It does not affect stability or traction control, unlike some other cars.

Save your money and check your pressures weekly for piece of mind.

 

Also keep in mind these newer low profile tires w/ stiffer sidewall can be hard to tell just by looking if they are low on air. Don't have TPMS on my current and prior set of wheels and like Sonic mentioned, check them often and invest in a quality air gauge. Something everyone used to have to do before this technology took over lol.

 

Yeah, I've owned 3 cars prior to my G and I've always had to manually check air pressure on my own, so it's definitely not something new to me. I didn't understand why I needed to spend $200-300+ on something that can be done for free. I guess TPMS is just for lazy people or people who don't know how to check their tire's air pressure (wow).

Not sure if it's quality or not, but I have a Tekton digital tire pressure gauge that I got off Amazon and it's worked fine for me in the past.

EDIT: And since I won't be getting any TPMS sensors, I just need to purchase valve stems for my aftermarket wheels, correct?

 

Many vendors will include the valve stems, but yeah, that's all you'd need and hub adapter rings if they're aftermarket wheels to reduce the chance of high speed vibration.

 

Un-earthing an old thread.
If I'm understanding correctly, Denso is the OEM sensor for our cars. Looks like they're about $110 for my 2010 :-( I hear that they're an easy plug and play though. No reprogramming/learning/etc required. What about the other oddball brands like Autel and so on? I don't have a TPMS scanner/programmer, but I did run a diagnostic with my BT OBD2 scanner. To my surprise, it was able to pinpoint my right rear sensor (code: C1704). I'm hoping its correct.
Any other advice on the most efficient way to replace the sensor and get rid of that annoying light? I can clear the code with my scanner but it comes back, so I'm assuming the sensor is truly bad.
