TPMS relearn IS setting the locations. What I meant was were they set before you replaced 1?

 

donbrew: Thanks for the reply. Not sure if I understand the question, but I think the answer is yes. Here is what happened was driving the car one day and the TPMS light comes on, I checked the DIC and the RF pressure was two dashes. When I got home I checked the tire pressure with a gauge and it was 37 psi. I drove it again and the light went out, but the DIC stated the RF tire pressure was 51 psi. It stayed off for a few days and then the TPMS light went on again and the DIC stated the RF with two dashes.
I replaced the wheel sensor in the RF tire and then proceeded to place the car in TPMS relearn starting at the LF tire and using my relearn scanner I would hear a honk and move onto the next wheel till all wheel where relearned and got the two honks of the horn
​​​​​​​The pressures on the DIC have been correct for a few weeks now, but every time I start the car the DIC states "Low air Add air" and the light is on. I can hit the DIC reset and the add air warning goes away but the light never goes off. I hope this helps.
I appreciate the help!
Thanks

 

Have you tried a reboot of the cars systems ? Also known as a battery lobotomy. Disconnect the negative battery cable for 15 minutes. That will reset all the systems in the car.
Can’t hurt to try.

 

firemangeorge: Thanks for the reply. As stated in my original post I did remove the negative battery post but for only 5 minutes. The results are above in the post. I know it probably was not long enough as the clock still had the right time. But the TPMS light was off. You think longer would make a difference? Thanks

 

The question is: were the positions set correctly BEFORE the TPMS alerted you? Are you positive it was the RF that malfunctioned or was it the sensor that was last set at the RF then not reset after a rotation?

Is the pressure in the tires set to the PSI that the placard on the driver door sill states? Or, some random PSI that you thought was correct?

 

donbrew: Thanks for the reply. Good Morning...Prior to changing the sensor I have not rotated the wheels in over a year and did not rotate after the sensor change.
The place card on the driver side sill states the tire pressure is the be 35 psi in both the front and rear tires and 60 psi in the spare. I have always kept the tires at these pressures.
Maybe i'm not understanding but if I put the TPMS in relearn and go around the car with the sensor reset and relearn tool does this not set the sensor to the specific scanned wheel?
I will go out today and plug in my scanner and make a few screen shots.
Thanks

 

Here are two screen shots. Your looking at the RF information. The other wheels have the same information other than the pressure are slightly different.

 

I disconnected the battery for an hour. TPMS light was off till I got to the end of the driveway.
I brought up the DIC with the tire pressures and verified as I let air out of each tire, the lost corresponded to the correct tire location.
Thanks

 

Somebody has edited the firmware placard. It is expecting to see something higher than 36 PSI
Learning the sensors SETS THE POSITION. There is no "programming" the sensor. There are 4 data slots for the tire locations in the RCDLR, each sensor has a serial number that goes into a slot. The first slot is LF the second is RF the third is RR the fourth is LR. ALL programming is to the RCDLR, I.E.: matching the sensors to a slot in the RCDLR.
There is a firmware Tire Pressure placard that can be edited.

Hope that’s not the car battery reading only 11.7 volts.
