Vehicle: 2006 Infiniti M45 Luxury
New sensors: https://www.ebay.com/itm/233612792280

I am broke. So a trip to a bloody dealer or a fancy tire place to reset is my last resort. Had been driving with dead-battery sensors for months waiting for tires to go bad. Finally replaced the tires and sensors at a local cheap-o tire place. Readings show *.* on all four. No tpms warning light on the dash. Drove 90+ miles since the replacement, no reset. I figured there is a procedure to reset the system.

I watched numerous videos and read posts on how to reset/relearn tpms on Nissan and Infiniti vehicles. None of those methods worked on mine.

I found the tpms wire/connector and used a paper clip to ground it. Both with engine off and on the tpms warning light starts blinking when I touch the ground 6 times. It remains blinking until I start driving. It goes away in seconds and does not come back solid or gets readings. I set pressure in tires as in picture.


Carefully followed instructions from forums and this article:

Help.

I can't help to notice that the 06 M45 isn't listed as a model for those sensors. Did you cross reference the exchange numbers with an OEM Infiniti parts website? I bought sensors on eBay one time too and when I went to Infiniti, their device couldn't even get a signal.

I checked. Noticed the 2008 M45 in the list of compatible vehicles on ebay, went on RockAuto.com to check part numbers. They are the same for 2006 and 2008:
SCHRADER 28204 - Alternate/OEM Part Number(s): 407001AA0A, 407001AA0B, 407001AA0C, 407001AA0D, 40700JA00C, 40700JA01B, 40700JA01C, 40700JA02B, 4321182Z10

The ebay item lists interchange part number: 40700-1AA0B, 40700-1AA0D, 40700-JA01B, 40700-JA02B, 40700-1AA0C. That's 5 matching part numbers. Also the frequency of 315 is the same.
New sensors came individually sealed in bubble wrap pouches and a box and appeared to be brand new and never installed before.

I don't think the new sensors are the problem. I can't get my car into the learning mode as described in posts and shown in videos.

I don't understand why the blinking tpms warning light goes away as soon as I start driving the car.

The paperclip trick may be causing your problem. Anyway the Factory Service Manual for your car lists the correct procedure on page 20. Here's the direct link to the ROAD WHEELS & TIRES section.

ID REGISTRATION WITHOUT ACTIVATION TOOL

Typically you may have to program the sensor to accept New IDs since they are new sensors, then they will automatically learn to the vehicle. If none of that works chances are they are not compatible with your vehicle. There isn't a whole lot on your own or with a scan tool you can do to make them learn to the vehicle. Some Nissans have a reset button for the TPMS but this one does not. So yeah I would try to program the sensors to learn new IDs, you could take it by discount tire and have them try to reset the sensors, just say you need them reset, or that your TPMS light is on. They do it for free and typically make their money by selling folks a new sensor.

Thanks to all who replied. All diy methods failed. Next step - discount tire as "LIBRILZ" suggested.

No problem! I worked there years ago.

Is there a way to tell if the sensor has a dead battery. I have a reading from only one tire on the display. However, sometimes the display reading did not coincide with the actual tire location. If anyone has had anything similar, please let me know.

Quick update with a happy ending. I stopped by a local Tire Plus and they were able to reset my TPM system and they did it free of charge! I tipped the mechanic.

This is the sequence:
1. He checked and confirmed that all the sensors are good by scanning each of them. His scanner showed the frequency and battery state. - KingAK22 this can be helpful with your situation.
2. Car on & Engine off. He scanned sensors again, Front Left, Front Right, Rear Right and Rear Left in this order.
3. Connected an OBD dongle to the scanner and connected to the OBD plug of the car.
4. Sent reset command with locations of the sensors to the car's TPMS.
5. Sensors started to show up on the screen on my way home. Approximately after 15 minutes of driving all 4 sensors were talking to the car and displaying values.
