How to wake up & activate brand new TPMS sensor.

If you bought a brand new sensor and it appears to be dead - you try to scan it with TPMS tool and nothing happens, chances are it is just needs to be activated, or woken up. These sensors come dormant from the factory to prevent batteries from discharging while sensor are still sitting on the shelf in the store or warehouse.

To activate brand new sensors, install them onto the wheels, inflate the tires to normal operational pressure, and then try to trigger them with the TPMS tool. It should work most of the times. If it still doesn’t, try releasing the pressure continuously for at least 3 seconds while triggering the sensor. This should wake up the sensor and you should be able to register it now.

I have a set of wheels that I had put aside for six months after installing the TPMSs in the wheels, car didn’t recognize the sensors when I reinstalled the wheels, your tip on waking them up by letting the air out for 3s seems to have woke them up and the car now sees the sensors. Thanks! Saved me a trip to the tire shop.

This worked, thank you! I had only done TPMS relearns four or five times before, and I had never ran into a sensor that wouldn't trigger with my Autel MX808S-TS (other than known bad ones). I had four new OEM Ford TPMS-35 sensors installed today and one wouldn't trigger when I tried a relearn. I tried three times and was convinced that I had a defective one.

After watching your video I tried to trigger it while releasing air from the valve stem, and after about four or five seconds it still wouldn't trigger. I stopped releasing air and was ready to give up on it and heard that beautiful "beep beep beep beep" and looked down to see that the sensor had been recognized! I was literally in the process of standing back up when it triggered.

Thank you for the video, despite the fact that I don't yet have a sensor scanner .

Thanks for your help. I had installed new sensors, and was not able to program one of them. Releasing air and hitting it with the relearn tool did the trick. Thank you Thank you!!!!

Nice video wish they were all like this lots of information in short time with no annoying music dogs or cats

Just so you're all aware in case your pressure light is on and you think the problem is one of your main 4 tires has a bad sensor make sure you check the spare tire as it also has a pressure sensor

Thank you for the video. I was wondering why I cannot scan my brand new out of the box REDI-Sensor and I was about to return it. I'll get it installed and then try scanning it.

[sniggitty]

on target this exactly what i needed. taking the air out and waiting a minute and then re trigger is correct

I have a toyota and the software to input the new sensor ID. It shows on the cars computer now but will I need another tool? Can I install and using the toyota software check things? Under the dash of my prius there is a tire pressure system reset switch. Maybe I'll need to hit that also.

Does not work. Brand new sensor. Deflated, drove around, inflated etc, no change.

[skiffman]

Thanks for the video. I tried this for a Continental Redi-Sensor SE10008 and deflation as well as a magnet does not wake these sensors up. I did see a SnapOn tool that had an activation capability within the tool where my Autel does not.

Suzuki Vitara S. I did manual tpms reset procedure and programmed all id's (automatic re-learning didn't work). I hope successfully as at the end tpms led was solid for approx. 5 sec which means success as far as I found. However I have another problem. After turning ignition on and reaching approx. 30 km/h, tpms led is blinking showing with this blings digits 1, 2, 3 and next it blinks for approx. 10 km-12 according to sequence "long off, short off". After approx. 10-12 sec it blinks agains digits 3, 2, 1 (in reverse order, each digit is being blinked few times) and then I got the correct pressure values displayed when I enter tpms menu (earlier there is nothing). Do you perhaps know what this 1, 2, 3 - long off/short off - 3, 2, 1 sequence means? Is that some kind of calibration? And the problem is that this "calibration" procedure is repeated every time after turning off and on the engine (only if the engine is off for short time the system doesn't run again calibration). How to "remove" this "calibration"? There are not DTCs codes visible for typical diagnostic software.

I put on a different wheel because my original had a crack in it and now my sensor light won’t go off. After watching your video, I realize that the sensor is connected to the wheel. Is it possible to take the sensor from my old wheel and put it on the new one?

[dougS]

After I wake them up, My Saab 9-3 will already know which rim they are on. Saab does this by signal strength from each sensor. It's just a matter of kicking them out of bed! LOL! I'll probably end up trying the deflation method. They are MoreSensor compact pro TX-K001 sensors. What's your take on this?

[DEADLOK]

What If I buy a regular tire or tires for spares and I have the current ones. Do I still need to program the sensors on the new spare? And I am not talking about the emergency spare.

[juanchoman]

Can you see if tool and tps sensor work before putting on car dont want to pay 80.00 to put them on and it not work

[lavazakoffee]

I have unreadible only one sensor and as per instruction I must have possibility to read all sensors ID from the car and after to copy to new one.But I can not on bmw g30 2017, 2019.

[mjlutz]

I got from the continental (redi-sensor) tech line that Autel's maxiTPMS tool won't activate their "new generation" sensors. Never had a problem before...

[HybridEnergy]

Man, I have to buy a specific stupid tool just for tire pressure sensing? foolish tech, I'd rather go back to having cars just not equipped with this, it's not like it's hard to tell when you are low by air in a tire for crying out loud. The tire dash light doesn't bother me enough, I'll just leave it, f that. Or take apart the dash and get rid of the led.
