2018 Ram 1500 - TPMS Not Reading 4th Tire

[jpb3jpb3]

Hey All,

Have a 2018 Ram 1500 3.0L V6 EcoDiesel - On April 15, 2022 my passenger side rear tire stopped working and would not communicate a tire pressure reading. I took my RAM to Discount Tire, they advised to buy a new sensor. So I purchased a new sensor $70 bucks and they installed it.

After installation, they said drive for a day or so and it should pair on its own to the RAM.

4 weeks later - May 15, 2022 the sensor still has not paired. I went to a secondary discount tire location, where they replaced the sensor again on 06/12/22. They said the same thing, drive for a day and it should pair on its own. It is now its 6/14/22 two days later and still the tire sensor is not communicating with the RAM.

I have read on this Forum elsewhere about the module under the front of the truck. ( Additional details - 3 out of the 4 sensors are working properly and remain working).

Should I take it back to Discount Tire again or have someone else look at it ? [ Sort of annoyed at Discount Tire - feel as if they are not aware of how to actually solve my problem. ]

Truly appreciate the feedback and advise.

I would take it to another tire shop, they probably never replaced the sensor and are ham stringing you around.

It could be the module at the front. It could also be the connection and wiring harness to that module. Normally those modules fail and don't register PSI on any of the corners. All you get for all 4 positions is -- --

Thank you for the advise.

Is accessing the module difficult and should I disconnect the battery prior to disconnecting it ?

Try moving the tires around just to see if their sensor registers in a different location.
