TMPS sensors for my second set of wheel (winter tires)?

[SimmZ]

As you may know, I just bought a brand new 2019 RAM 1500 Classic, then since I live in northern Canada, the dealer gave me (for free) with the truck as set of steel rims (17") and winter tires (nice ones!), however they didn't wanted to included the TPMS sensor because they said that the genuine Mopar sensor are more expensive that the steel rims, so they wanted 250$ (CAD$) extra for 4x TPMS. I didn't accept that since you can find very good quality OE compatible sensor for like 15$ a piece on eBay or Amazon and they are all rated 5/5 stars by actual owners. So my dealer accepted to mount the OE compatible TPMS I ordered online on the wheels (for free), but they indicated that they may not be able to "program" them (and I need to pay for that service later) when putting the winter wheels on the vehicle later this year because they are third-party sensors???

It sounds like complete ******** since I watched video on Youtube and even used the online chat from TireRack and the guy told me that all Chrysler's vehicle for like 10+ years ago are auto-learning and then will initiate new TPMS automatically after driving AT LEAST 25 miles at 25 MPH but it can be a bit more longer. The only different is that the dealer have a programming tool that initiate IMMEDIATE TPMS learning, because obviously the dealer's mechanist don't want to drive all client's vehicle for 25 miles+ to install new TPMS.

Is that correct? I don't want to wait until winter to see by myself! LOL

If you get the OEM ones they tend to synch right up within a few miles of driving. The programmable ones don't.

Well, the sensors description I ordered online indicates it's a direct replacement for Mopar part number 68249197AA which is the correct PN# for a 2014-2019 RAM... so it doesn't look to be "universal fit" ??

Those look like the right ones.

Hello, I left my stuff in my office but I just got back from an ASE instructor conference in Frisco, TX. One of the classes was TPMS. Only one company makes all the sensors. The Mopar sensor is the same cheap sensor on amazon. The GM sensor is the same cheap sensor on amazon. The TPMS tool is easy programming but you can also let all the air out of the tires and fill them back up to learn the sensors. Some new systems will learn the sensors when driven above 25 mph for a set amount of time. TPMS system set lights at approximately +- 4 psi. If the light is solid the problem is air pressure. If the light flashes, it is a hardware problem. If I can remember, on monday I will scan the manufacturer coarse booklet for your reference.

are you saying we can just reteach our Ram sensors if we change to a tire with air pressure that's outside of the current range by letting most of the air out of the tire, refilling to the new air pressure then drive? and how low? 10lb? 20?

I have not done it yet as I have the proper tools but I was informed that...

Tire pressure sensor retraining

Using an RF signal, each sensor transmits tire pressure data approximately once every minute. Each sensor’s (transmitter) broadcast is uniquely coded so that the WCM can monitor the state of each of the sensors on the four rotating road wheels. The WCM automatically learns and stores the sensor’s ID while driving after a sensor has been replaced.

There is no formal retraining procedure necessary. Drive the vehicle for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h). During this time, the system will learn the new sensor ID code and will clear any DTCs automatically. If a sensor cannot be trained, see appropriate manufacturer service information.

A new sensor ID also can be programmed directly into the WIN or TPMS module by using a RKE-TPM analyzer in conjunction with a scan tool. Once the new sensor ID has been programmed, the vehicle will need to be driven above 15 mph until the fault is no longer active (lamp extinguishes) and display is updated (for up to 20 minutes).

I hope this helps.

I bought a set of $40 sensors off of Amazon for my new wheels so I could keep my old set of wheels/tires together and they work just fine. Took about 5 minutes to learn.

Awesome man! Thank you so much for these valuable informations. I was pretty sure myself that all TPMS may be built at the same place (in China as well), no matter the brand. I work it IT for 18 years now and several computers parts are all built in the same manufacture also, no matter which brand (or "no name brand") it is! So it can be annoying when you buy the part marked as "genuine" and paying twice the price of the "generic" brand part to get the exact same thing... Thanks again!

They filled you full of BS. Several companies make sensors, the 5 big ones are Schrader Electronics, VDO (both make for FCA), TRW Automotive, Pacific Industrial Corp, and Lear.

you also don't need to let all air out to relearn. a 2 to8 psi change, increase or decrease will trigger a sensor from sleep to live, sending a signal to the rf receiver, allowing it's unique id to be learned and stored. wheel location will be learned also if the system has that feature.

no, this change has to be done in the vehicle computer. the sensor only transmits psi, some advance sensors on luxury / performance vehicles transmit temperature also.
