Many Toyotas that have a full size spare monitor the tire pressure in the spare as well and people often over look checking this. If a tire pressure monitoring sensor is bad a scan tool is needed to look at the validity of the data from each sensor to determine what is wrong.
there is a push switch under the base of the stering wheel that would correct that problem
