tire pressure monitoring help!!

[epoy]

hi everybody.

i set my TPMS at 32 psi.
i checked my tire pressure today, all four tires had 31 psi.
just wondering, i followed the owners manual for setting the TPMS warning/activation.

why no warning came out from my car?
is there something wrong?

i drive SE 2008.

thanks

It comes on when there is alot bigger difference between the tires. Or, how is the pressure in the spare tire? I dont remember if the spare has a sensor or not?

[hossmaster]

technically the condition does not warrant a warning. now if 3 tires were at 31 and one was at say 26, then yes you would get a warning.

The spare does not have a TPMS sensor.

It takes about 6 psi below the TPMS set pressure to light your TPMS warning light.

the light doesnt come on unless it hits the threshold, which is 5-6 psi below the assigned tire pressue (32psi)
the spare doesnt have a TPMS sensor.

Do they all have space saver spares?

N.E.O.

Just in the USA - GEN6.................for the noobs......for the 15th time in 2 1/2 years.

In other words, there can be a fifth tire pressure sensor in the standard size spare, that is what I am saying. And full size spare is an optional equipment in the USA, so how can you say that there is no sensor in the spare so quickly.

What the hack do I know, I am just a newbie. BTW, it is n00b.

N.E.O.

I think the TPMS warning only come on when the pressure is on the low side. I once measured 45psi in my tires on a hot summer day after a long highway drive. The TPMS didn't come on than. Of cause it is not safe to drive with such high psi so I'm not going to try that again... and of cause I lower the tires' pressure.

There is no option nor is it standard for a full size spare on Gen6 in the US.

You're wrong again................

[new echo owner]

How so? In what regard am I wrong?

The information about the optional equipment is from Toyota.

N.E.O.

It wasn't available as an option in 2007 and is not shown as an option on toyota.com for the 2009 USA Camry.
