Tire sensor recovery?

[wreckwriter]

So when you run DRs without sensors I assume the TPMS freaks and throws warnings. When you put the street tires back on does it just recover on it's own? Any major delay or any other issues I need to know about?

Thanks!

Mine did refind the sensors, but the first time I actually drove Tigger to Milan on the DRs, the next time I swapped Wheels at the track and ran for a couple hrs and the computer didn't notice the change, so I was able to put the nonDRs back on and never miss a beat.

[wreckwriter]

Cool. Thanks Jay. I'm going to get mine mounted today and figure I'll drive them for a day to wear the little tits off before I race them :)

We do need pic's you understand. :)

Mine always throw a code om the way home , but when you reinstall the stock tires the code will go away.

[wreckwriter]

We do need pic's you understand. :)

I'll do my best :)

[Featherburner]

I'll do my best :)Your best won't be good enough unless the results are pictures. lol.

[wreckwriter]

Your best won't be good enough unless the results are pictures. lol.

They're already taken, just need to be dumped off the camera. Patience :)

Sweet!

[Featherburner]

Patience :)Ha, I'm a gearhead, that word isn't in my vocabulary. :)

My snows took probably 3-4 ignition cycles to finally pop a code.

What's weird is that once in a while it goes away as I have the stockers sitting in the garage!

lol

while were on the subject, someone answer this for me. is the tpms in each wheel coded for a specific position in these cars such as lf, rf,lr, rr. the reason I ask is that my onboard worked fine when I bought the car, I could put air in the Rf and watch pressure go up in the Rf, but now that they've been rotated, it's all fucked up. I put air in lr it goes up in rf, I put air inrf it goes up in rr, someone elaborate please.

Check pages 9-53 and 9-54 of the owners manual. It tells how to reset their locations after rotation.
Edit: here it is.
If the TPMS is not functioning it
cannot detect or signal a low
tire condition. See the dealer/retailer
for service if the TPMS malfunction
light and DIC message comes
on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time one or
more of the TPMS sensors are
replaced or the vehicle’s tires are
rotated, the identification codes
need to be matched to the
new tire/wheel location. The sensors
are matched, to the tire/wheel
locations, in the following order:
driver side front tire, passenger side
front tire, passenger side rear
tire, and driver side rear tire using a
TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. When increasing
the tire’s pressure, do not exceed
the maximum inflation pressure
indicated on the tire’s sidewall. To
decrease the tire’s air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match
each tire and wheel position.
If it takes longer than two minutes to
match any tire and wheel position,
the matching process stops and you
need to start over.
The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press and hold the Remote
Keyless Entry (RKE) transmitter’s
lock and unlock buttons, at the
same time, for about five seconds
to start the TPMS learn mode.
The horn chirps two times
indicating the TPMS receiver is
ready and in learn mode.
4. Start with the driver side front
tire. The driver side front
indicator lamp also comes on to
indicate that corner’s sensor
is ready to be learned.
5. Remove the valve cap from the
tire’s valve stem. Activate the
TPMS sensor by increasing
or decreasing the tire’s air
pressure for about eight seconds.
The horn chirps one time to
confirm the sensor identification
code has been matched to
the tire/wheel position.
Vehicle Service and Care 9-53
6. The driver side front indicator
lamp turns off and the
passenger side front indicator
lamp comes on to indicate
that corner’s sensor is ready to
be learned. Proceed to the
passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side front
indicator lamp turns off and the
passenger side rear indicator
lamp comes on to indicate that
corner’s sensor is ready to
be learned. Proceed to the
passenger side rear tire and
repeat the procedure in Step 5.
8. The passenger side rear indicator
lamp turns off and the driver side
rear indicator lamp comes on to
indicate that corner’s sensor is
ready to be learned. Proceed to
the driver side rear tire, and
repeat the procedure in Step 5.
9. After the driver side rear TPMS
sensor has been learned the
horn chirps two times. The driver
side rear indicator lamp turns
off and the TPMS sensor
matching process is done. Turn
the ignition switch to LOCK/OFF.
If no tires are learned after
entering the TPMS learn mode,
or if communication with the
receiver stops, or if the time limit
has expired, turn the ignition
switch to LOCK/OFF and
start over beginning with Step 2.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.
Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, for
signs of wear or damage.
See When It Is Time for New
Tires on page 9-56 for more
information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). See Scheduled
Maintenance on page 11-4.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that your vehicle
continues to perform most like it
did when the tires were new.

featherburner, what a pain in the ass this is. Thanks for the info.

[wreckwriter]

I drove mine lightly for 2 days with the DRs on, it never did recognize there were no sensors on the rear wheels.

[Danl]

I purchased an oem tire and wheel set up with sensor. I took a rashed wheel off the car and put it in the trunk as a spare. When I did this, after short travel distance I show complete sensor failure. I don't get a read on any wheel. Is this because I have five sensors in the car? Any suggestions?

[wreckwriter]

Did you recalibrate as per owners manual?

[EcoBrick Bob]

I had 2 in trunk with TPMS and I recalibrated with no problems on first try! Still have a spare with TPMS in trunk.

When I switched my GTO wheels on 09' G8, it took 3 days before I got a TPMS failure....

Only thing I could think of was that the 4 takeoff wheels/tires were stacked in garage and car was reading them!

[Danl]

No, I hadn't tried to recalibrate yet. So it is ok to carry a spare with the sensor and it wont affect anything, I just need to recalibrate. Am I correct in saying you have to calibrate every wheel even when you only change one? And while on the subject. Are the sensors in the valve stems, or do they stick on the inside of the wheel? Thanks for the help.

[wreckwriter]

I think you must recal all even for changing one.

[piecesparts]

Another website for GM cars came up with a great idea. Take the sensors off of the wheels and put them into a short PVC pipe with a cap on each end and a valve stem instslled into the cap. Air up the tube to about 32# and throw it into your trunk. Never worry about sensors again---No matter which tire you run.

NOW, does anyone know how big around the sensors are, so I can get the right size pipe piece?

[Danl]

I read the owners manual. The section that covers the tpms does not tell us if they are part of the valve stem, or if they are stick on sensors inside of the wheel. I am going to powdercoat the wheels which will require me to remove the valve stems. If they are part of the stem, will I have to replace them, or can they be removed and reinstalled? As far as putting the tpms in a pvc pipe in the trunk, would you need to use 4 of them to represent all 4 tires?

[TomPierce]

the sensors are part of the valve stem -

[Robert@KBXPerformance]

Why not just run the TPMS in your set of drag radials too? I did a full set on all 4 corners with TPMS as well. Works fine if you don't mind rolling around on the DR's on a daily basis.

Featherburner, thanks for the info on calibrating the TPM sensors. I installed my new wheels with new TPM sensors a week ago, and thought that everything was good until I got the TPM failure light last night. I really like the way that GM made it so that the corner marker lights and horn tell you when each wheel's sensor has been detected. It only took a minute to get all 4 done.
