So, if I buy a set of 2019 wheels with the original TPMS sensors in them, and put them on a 2008 4Runner, will the new sensors still be recognized by the 2008 4Runner? Or will some sort of reset be necessary? Or are they not compatible?
They wont be. Each tpm sensor in each wheel emits at certain frequency and this frequency needs to be loged into you 4runner. Dealers could do that easily in like 30 mins and it costs $70 here in canada. A tire shop could do that too probably, just call them and double check.
If I were going through the expense of buying new wheels, I would be installing new tires and having them mounted and balanced I would just get all new sensors. Cents on the dollar with all the other costs involved.
I just put sensors from a 2015 in some trd rims today. Tire guy synced them up to my 2007 no problem. I think mid 2006+ are all interchangeable.
Put new OEM (for a 2019) TPMS sensors in my ORP wheels and Discount Tire couldn't get them to sync with my 07 Limited. Haven't tried the dealer yet. Said the spare being the stock sensor might be the issue.
Thought I would share an update. I bought the 2019 wheels, including the spare. I put the five 2019 wheels on my 2008 4Runner, and all is good. No lights, no nothing. All is good, no reset or anything else needed. Just like the good old days!
Just an FYI...IF you had the original wheels anywhere close by your 4R was still sensing them so no TPMS light triggered, even if you drove away several miles it could take a bit of time for the system to react to them missing, since any new sensor should need to be entered into the ECM for the system to recognize it, the light could come on several days later after the system gives up searching for the signals.
I hope that's not the case with your new wheels...a simple test you can do to know for sure, drive your 4R to a gas station that has air available well away from your old sensors and let the air out of one of the tires to see if it will trigger the light to come on.
Let us know the outcome.
Well, drove it yesterday, far away from the old wheels, and it was fine for a while, then the tire pressure light came on.
After getting back home last night, it went off again, when the vehicle was closer to the old wheels. So perhaps you are right.
