Aftermarket TPMS sensors for new wheels

[ArthurKotb]

I got the other 4 sensors installed yesterday and was able to get them registered in Autel and ultimately written to the ECU. My TPMS light is no longer flashing.

It's not the weak battery causing the problem. I had all 5 tires off the T4R and I had given the tire store instructions on which sensor went in which tire. The tires were labeled with a tag; location on vehicle and sensor ID. The boxes with the sensors were labeled with tire location.

I scanned the front left and it returns the code for rear left which is sitting 12' away in the back of the garage (the first tire done 3 days earlier). I scan again and it says it's the ID for one of the old sensors in a box on my workbench. I scan again and it says it's the ID of the right front tire. I roll the tire down the driveway (15-20') and it scans correctly.

I roll it back and scan the front right. It scans 'duplicate'. I roll it down the driveway and scan it. It scans correctly. I then roll the others down the driveway, one by one, and scan them. Then I open the 'Diadnostic/TPMS Diagnostic' section, and write to the ECU. All is good.

So yes you can use the Autel, but it's not going to work unless you take each tire 15-20' away from the rest. I am happy to have the light out, new sensors in all the tires and about $1600 still in my pocket.

my sensors are original from 2007. batteries most likely dead in all of them. i'm installing new tires soon, and have decided, since the TPMS is a stand alone dummy system, i am not going waste the funds to replace them.

I have an early 2004, purchased fall of 2003. I had 1 dead sensor, 3 weak and 1 still tested OK. The Autel was $200 on Amazon. Subtract that (if I return it) from the other costs and it was about $200 for the sensors and installation.

I was going to forego replacing them but I do find it handy to know if a tire is getting low, especially in winter. I check my tire pressure every few months anyway but I've had slow leaks where the tire is 10 lbs. below where it should be in just a week. I pull a travel trailer on long trips and a tire that's low on air generates heat and can explode. So from a safety standpoint I decided to see if I could replace them myself.

Besides, that blinking light was driving me nuts.

Working with the support team overseas they were able to figure out that instead of selecting my model year (2004) from the menu selection, I should use 2017. When I changed to that setting, reading the tire sensor was close to immediate and correct. It took less than a minute to go around the car and read all 5 sensors. I compared with my notes on the sensor install and they were 100% correct. I'm going to guess that the Denso sensor is a newer version and is now not related to the model year of vehicle.

So happy camper, tool is working, sensors are updated, no blinking light
