TPMS sensor replacement / error code

The car battery has nothing to do with it. A bad tpms sensor battery is one possibility.

You either have a bad sensor, bad sensor battery (internal coin battery) or the guy did not program the car's TPMS ecu properly with the new sensor ids.

I have seen aftermarket LED headlights cause enough rf interference to cause the tpms sensors to be flakey. All this takes to remedy is to turn off the LED headlights.

I would take it back and have them fix it.

You should not have to tell them how but essentially they should be able to rf scan the wheel sensors (typically with an Autel tool) even with your car off to verify what each sensor's status is (working or not) and to record each sensor's unique id/serial number. They would then verify those serial numbers are properly written to the TPMS ecu.

While not the same interface as an Autel, the following represents Techstream monitoring the realtime sensor ids and data points (pressure and temp). The red notes recorded the changes I made.



The sensor locations are not automatically populated in any particular order. If you had Techstream or similar and noted one sensor was offline you can reduce each tire's pressure by ten pounds and note which sensor id does not change

An Autel rf tpms tool can pinpoint the bad sensor's location since it is used next to each tire.

Finally some newer Toyota's have the ability to read and setup new sensor ids without any tool or scanner. However gen3 Prius' do not have automatic new sensor id write capabilities.

 

The tpms reset switch is used with ig on (two power presses without brake). It takes the current pressures and sets a lower alarm pressure. It has nothing to do with setting up new sensor ids.

Be sure to do this properly first but its unlikely to be your issue.

 

No they don't have to clear old ids. Have them do it again and get all the ids for your own records.

You could take the car to another good tire place like Discount Tires but why get hosed twice?

Toyota and others with Techstream would have to remove the tires to get the ids.

I assume you have no LED aftermarket headlights.
