TPS issue

[hiker1]

Had a new set of tires installed on my '07 Ranger XLT ext cab last week. Now my tire pressure light is on. It flashes for a while the stays on solid. Can't find any info about the TPS system for Rangers and I know if I go to the dealer they'll take an arm and a leg plus my 1st born. Can anyone offer insight or help? Thanks

Its called TPMS, tire pressure monitor system
TPS is throttle position sensor

Which may be why you didn't see any info on it

Go back to the tire shop that installed the new tires and have them reprogram the sensor in each wheel, they will have the handheld unit to do that, no reason for you to buy one, only takes a couple of minutes


2006 and up vehicles were required to have TPMS
There is a pressure sensor inside each wheel, it uses a wireless transmitter to send data to the TPMS unit
The batteries in these sensor do wear out, 7 to 10 years is expected
Each sensor has a unique ID which the TPMS needs to associate to each corner of vehicle
Thats where the handheld device comes in
If you rotate the tires or switch them around then TPMS needs to re-learn each location
So it has a reset/re-learn mode that is used to calibrate locations again, using the hand held device

Since you have a 2007 your sensors are 13 years old, so they are either the 2nd set or are 1st set starting to die

If the light was out before tire replacement and is now flashing its more likely they clipped a sensor while breaking beads.

Like RonD said. Take the truck back to the shop that installed your tires. It's on them to make it right and on their dime, not yours. This is assuming the purchase was recent and you haven't let the issue drag on for a while before looking at fixing it.
