Aloha, I'm looking at these Schrader 33700 EZ Sensor TPMS in black. Reasonable price at TPMS.com and TPMS Direct.
has anyone used these?

I see that Schrader is the OEM manufacturer.

ThanksDenny

 

That's what came with my new wheels, no issues.

 

Yes they are the same and Rock Auto carries them too for $22 each.

 

FYI, these look great with the black option. Worked perfectly no need for relearn.

👍🤙

 

The EZ sensors must be programmed using the Schrader programming tool before they will work in your car. They will also have to be registered to the car.

 

I just installed my new rims and tires new TPMS yesterday and took a drive today no programming whatsoever. Works perfectly.

 

From Schrader's website:

Part No.: 33700
Commercial Name: Schrader Clamp-in Programmable EZ-sensor 314.9 MHz / 315Mhz / 433MHz
OEM Sensor P/N:
Ean Code: 5054208007083
Nut Torque: 71 in-lbs (8 Nm) Nm
Screw Torque: -- Nm
Valve Core Torque: 3.5 in-lbs (0.4 Nm) Nm
Note:EZ-sensor must be programmed prior to installation and relearned to the vehicle. A Programming Tool compatible with EZ-sensor is required. For maximum coverage, ensure your TPMS tool is updated to the latest software available.

 

Dude, you're killing me. I'm just stating what I did and what I bought and it works without programming.
I even bought a cheap Amazon programmer just in case but never took even took it out of the box.

 

The EZ Sensors are programmable so they can work on a large variety of cars. If you did not program them, how are they working at the correct frequency and data protocol for your car. And if you did not do a relearn procedure on your car, how does the car even get data from them?

It might be that your car has not realized the original sensors are no longer present and you are seeing old tire pressure values. I have experienced that on my car when I first started doing TPMS replacements. I thought the new sensors were working and then after a few drives I got the dreaded "--" for pressure readings. Try letting some air out of one tire and see if your display correctly indicates the low pressure.

Or perhaps whoever installed the TPMS sensors already did the programming and relearn procedure for you? If you mounted the tires and sensors yourself, obviously you would know that was not the case. But if a shop did the work, they might have set you up without even mentioning it.

I am not trying to bust your chops, I just have done a lot of TPMS installs (over 100 cars) and what you are saying does not make sense and is in conflict with what the manufacturer says. Are you suggesting Schrader is wrong about their own product? I love Schrader TPMS sensors and use them for all cars they support.

 

TPMS.com pre programs the sensors to 433 MHz if ordered for C8
Before shipping. I haven't driven the car on a long ride yet but the pressures did change while I was driving. I guess only time will tell and if they do go out I have a programmer in my toolbox.

Aloha

 

I love when people argue with the ones who have actual experience.

 

OK - now we are getting somewhere. Schrader is right and they do need programming but if you order from TPMS.com, they do the programming for you. If you order those sensors from Rockauto, they will not be programmed.

Of course it works, just like everyone else who has replaced the sensors. And, it does not say "registered" to the car - it says relearned. Which is true, and it is why the car has a relearn feature. The purpose of the relearn is so the car can 1)recognize the new identification code and 2) determine the location of the TPM on the car. No tool is necessary for that process to work. Some prefer to use the tool method, then it is ready before driving -but that's preference, not a requirement.

As for programming in advance, I have no basis to disagree, but generally no one has reported that being necessary - so it must generally be done before shipping if it is necessary (perhaps with aftermarket parts). The Service Manual discusses the learn feature but does not say anything about programming it in advance - presumably that's because it assume an OEM sensor is used.

 

Update

.. Schrader 33700 EZ Sensor TPMS sensors works perfectly.

No programming needed

 

The C8 will automatically relearn the sensors, generally within seconds, sometimes it takes a few miles. It relearns every time you rotate tires from side to side, or switch between summer and winter or street and track wheels. If it were trying to read the old sensors which are no longer near the car, it would show an error.

 

Just so happens I rotated the tires on my C8 today using my Quickjack. The right rear tire had been a little low on pressure and the low reading moved to the left rear immediately after I pulled out onto the street.
