2007 Silverado TPMS
I have a 2007 Silverado. Just bought new tires and had 4 TPMS rebuild kits installed. When I got the truck back it had the "Service Tire monitoring system" warning showing, showed 23 psi @ the left front tire...Tire company rep said it will take 4 or 5 miles, then it will correct itself???? Went back after about 10 miles and no correction shown, he relearned the positions but it still showed only 23 psi. His next comment was, well it sometimes takes several miles maybe even 2 or 3 different trips before it will corrected itself, but he promised it would correct itself. Anybody ever here of this procedure? Taking several trips before it corrected itself? All other tire postions read correct air pressure, it's just the left front (drivers side) So far have about 25 miles and it now shows no air pressure in left front???? It's not learning very well, it must be a slow learner?
It sounds like that TPMS sensor has gone bad. Unfortunately they aren't designed to last forever.

TPMS Sensor going bad
Thanks, thats what I thought, but they had just installed 4 new ones, the tire company rep checked that particular sensor and said it was sending a signal so it must not be the sensor. I guess I'll go back and complain again! These sensors have been nothing but trouble since I purchased the truck new.

I dont know if you have tried re-learning the tpms sensor yourself or not.But here is what to do, maybe this helps.
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the RELEARN TIRE POSITIONS
message displays. If your vehicle does not
have the DIC buttons, press the trip odometer
reset stem located on the instrument panel
cluster until the RELEARN TIRE POSITIONS
message displays.
4. If your vehicle has the DIC buttons, press the
set/reset button. The horn will sound twice to
indicate the TPMS receiver is ready, and
the TIRE LEARNING ACTIVE message will
display. If your vehicle does not have the DIC
buttons, press and hold the trip odometer
reset stem until the horn chirps twice and the
TIRE LEARNING ACTIVE message is
displayed.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve cap
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air pressure
for five seconds, or until a horn chirp
sounds. The horn chirp, which make take up
to 30 seconds to sound, confirms that the
sensor identification code has been matched
to this tire and wheel position. To decrease
air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air
pressure gage, or a key.
7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the confirming horn chirp for the
driver’s side rear tire, the horn chirp will sound
two more times to signal the tire learning
mode is no longer active. Turn the ignition
switch to LOCK.
11. Set all four tires to the recommended air
pressure level as indicated on the Tire
and Loading Information label.
12. Put the valve caps back on the valve stems
The spare tire does not have a TPMS sensor.
If you replace one of the road tires with the spare,
the SERVICE TIRE MONITOR message will be
displayed on the DIC screen. This message should
go off once you re-install the road tire containing
the TPMS sensor.
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the RELEARN TIRE POSITIONS
message displays. If your vehicle does not
have the DIC buttons, press the trip odometer

2007 tmps
You are correct, they were rebuild kits, thanks again for the info. That actually helps quite a bit, as the system was showing it needed servicing when I took the truck to them. So I will assume that particular sensor was bad to start with..

Thanks, I have tried the relearning process several times in the past, plus I did watch the tire rep. program them. I think I may have found out what the problem may be. I had the "service the tire monitoring system" warning when I went into replace my tires. The Discount tire guys replaced with rebuild kits, I'm now thinking they rebuilt one sensor that had bad electronics.Thanks to everyone for your help and suggestions..

Being an 07 and if the sensors have not been serviced since new, I would suspect the sensor is out, most likely the battery in it is dead...
Most tire shops and the dealership can read the status of the senors for you...most tire shops will do it for free, I can't speak for the dealership...
