Yes, that would be useful information (sorry). They are Denso 550-01103 TPMS Sensors. This sale is $60 for all 4. Denso 550-0103 TPMS Sensor
I wonder if the denso part no is equiv to Toyota part no 42607-33012? Could be. 2003-2017 Toyota Tire Pressure Monitoring System Sensor 42607-33012 | McGeorge Toyota Parts Amazon says yes, for me: (Above price is for one, in CDN funds.)
They are the right sensors for a 2012 v Five, and that's a smoking hot great price for the four, just don't know how well they age, and for how long prior to sale they were on the shelf.
You'd need to dismount the tire, replace the TPMS sensor, remount the tire, rebalance, etc. Or just hold onto them until you replace tires next time -- but therein lies the rub, how long is their shelf life?
I’ve heard you can just deflate, break the tire bead locally at valve, push down the tire with a knee, reach in to access/remove/install. When reinflating a little dish soap on the rim?? it’s not for me, have sticker shock over that Autel gizmo.
True, you could man-handle all four out and in. Assumes that no rebalancing is required. There are less expensive options than the Autel TPMS ID reader/programmer. We use the ATEQ Quickset tool to swap summer and winter tire sets, around $75.
Reads the individual TPMS IDs, stores them for later re-use. Stores two sets (of five, assuming a spare with TPMS) per vehicle, up to 4 vehicles. It's essentially a TPMS reading and flashing tool, the flashing being telling the Prius TPMS system what IDs to be monitoring. Otherwise, the Prius will continue to monitor the takeoff set of mounted tires on the rack in the garage. Ask me how I know...
I did a chat with Denso. They say, "The estimated lifespan of TPMS sensor are 5-10 years if connected to the vehicle. The life span would be longer if there just on the shelf and not connected to the vehicle's ECM." So, if it were installed on a car at purchase, and the car was very low mileage, it would be through about 30% of battery life. I think it would be conservative to say the batteries have about 70% of new battery life. I asked about shelf life if it had never been installed and they said they would get back to me. I will post any new information. TLDR: These TPMSs should be good for 3.5 to 7 years depending on how much you drive the car.
Putting it all together since it won't let me edit the original post: 4 unused TPMS for $60.00 They are Denso 550-01103 TPMS Sensors They were originally purchased in October 2017, so, about 3 years old but never used. Denso says 10 year battery life for low mileage cars - so, expect at worst they have lost about 30% of their battery life.
