need help on VSC TRAC, VSC OFF lights on, are they related to tire pressure sensor?

[abin]

was not a good day for me yesterday.
I went to a dealership yesterday to get TPMS issue fixed. I have tire pressure light on and got some time to have service people to look at if they can have it reset since I changed tires earlier this year.
Service people at dealership thinks the tire sensor for one wheel is bad, and needs to replace. I wondered if $325 worthy the repair, so they put a regular valve for that wheel. $120 was paid out of my pocket for this visit.
What caused my concern is, when I was about to drive off, I found, I got additional two lights, VSC TRAC and VSC OFF, now they are on.
Does the presence (or not) of tire sensor affect VSC TRAC and VSC OFF lights?
I did a search on our forum, but did not find a thread has this indicated.
Can someone help me?

Take a look at this thread: http://www.toyota-4runner.org/showthread.php?s=&threadid=32818&highlight=zero+point+calibration

From what I've seen, if the TPMS light is blinking then there is something wrong with one of the sensors? Was it blinking or was it just constant on?

came back from dealership, with the intervention of Toyota CS and management, "0" "." calibration on ECU was performed with no additional charge. These three lights are off now.
They were (including TPMS light) constantly on before they were fixed.
Now, I am missing one tire sensor.
But, as long as the TPMS light is off, it would not bother me too much.
$325 is too much for me.

Thanks to sharp4runr for providing the insight.

You should have a TPMS sensor on your spare. If you wanted to have a tire shop put that one on the tire that's missing one that might work well for you.

I always service the spare at my oil changes. By setting it to the max sideweall inflation, even 2-3 over, it always has enough air if I were to need it and you won't miss the TPMS on that tire. Good Luck :cheers:

That will be a good idea. meaning I can use "spare" tire sensor in spare tire. As someone suspected the TPMS light on can come from a flat spare tire.
If I don't get satisfied resolution on broken tire sensor, I may want to do this.

Only question is, do I have to do zero point calibration again?

Thanks, CJ3flyr.
