I'm close to buying tires (5 or 10 K from now) on the 2001 I recently bought. I'm wondering if the TPMS valves get reused or if they are going to tell me I need to replace them. If they need to be replaced should I buy them ahead of time? The tires on it are Goodyears. I read here on the forum another member was switching away from run flats and carrying a 12 volt compressor and tire slime. Any thoughts? I see a big difference in price between new Goodyear run flats and Michelin run flats. Any thoughts? Thanks, Bob

 

I would replace the sensors. Ten years is good life on them. I'm in the process now with my 02. Going with non run flats and carrying a compressor and a plug kit.

 

At 7-10 years I would buy new sensors from Gene, sell the old ones on that auction site and be happy (run flats or non runflats)

 

Thanks Baldfart and jcgunn that sounds like good information regarding new TPMS. I've been online looking at tire prices. I'll be doing more reading and decide on run flat or conventional. I also need to shop for a car cover as I park outside. The original owner always parked in the garage and the finish still looks new. When a friend saw it tonight he actually asked me if it was new. He was really surprised when I told him it was a 2001.

Edit to add; I'm new here, where do I find Gene? Thanks, Bob

 

www.gmpartshouse.com. Both Gene and Patric are great guys and very knowledgeable.

 

Thanks very much. I see they have this listed;


||--Genuine GM C5 Tire Pressure Sensors/TPM--||

2001-2004 Sensors

25773946 – sensor – $41.37 each
15234846 – nuts – $4.03 each

Total setup of 4 is $181.60

Note: The sensor comes with the washer and valve stem cap.
Setup includes: 4 sensors, 4 washers/o-rings, 4 caps and 4 nuts.

Are these parts to rebuild the units or complete units? This is my first hobby car that is modern enough to have TPMS and I am clueless.

 

Those are the complete units ready to install!

 

Thanks very much! Is there programming or anything involved when you swap them out? I wonder what would be affected if you got rid of them and used regular valve stems. No dout all sorts of digital mayhem would occur

 

Go into training mode and program them to the correct "corner". You'll need a BIG magnet.

If you don't fit TPMs you'll get a DIC warning every time you start the car. The warning can be programmed out with a Tech II.

Tire Pressure Monitoring Sensor Programming

The Tire Pressure Monitor (TPM) system interfaces with the Instrument Panel Cluster (IPC) through the serial data line. Once the program mode is accessed through the IPC, each sensor's unique identification code can be programmed into the receiver's memory. Each sensor must transmit the unique code in the proper sequence. A magnet must be held close to the sensor in order to force the sensor to transmit the identification code. The IPC will display a message as each sensor is programmed, and when to proceed to the next sensor for programming. The receiver also sends a message to the BCM to sound the horn one time, indicating that the sensor properly transmitted an identification code. If the programming sequence is cancelled before any sensor is programmed, or if the vehicle's battery is disconnected, the receiver will remember all current identification codes. As soon as the receiver learns the first sensor identification code, all previously stored codes are erased from the receiver's memory.
J 41760 Tire Pressure Monitor (TPM) Programming Tool.
Tool required (any medium strength magnet, U or Disk type
1. Turn the ignition to ON.
2. Press the RESET button in order to clear any IPC display warning messages.
3. Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
4. Press and hold the DIC RESET button for 3 seconds.
Notice: Refer to Body Control Module (BCM) Programming/RPO Configuration in Cautions and Notices.
5. Press the OPTIONS button again until the TIRE TRAINING message appears.
6. Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin
the programming sequence.
7. Install the J 41760 Tire Pressure Programming Tool over the left front valve stem.
8. The horn will sound, indicating the left front TPM sensor is programmed.
9. When the horn sounds, proceed to program the next TPM sensor in the following order as directed
by the IPC messages:
- LEARN R FRONT TIRE
- LEARN R REAR TIRE
- LEARN L REAR TIRE
Programming Cancellation
1. The programming mode will be cancelled if any of the following conditions are met: - The program mode is exited through the DIC.
- The ignition is turned to OFF.
- All four sensors have been programmed.
- The TPM system has been in the program mode for longer than 2 minutes and no sensors
have been learned.
2. If the program mode is cancelled with less than four codes stored, the receiver will only accept the codes programmed up to that point

 

This is a good question for anyone buying new tires. Many tires shops will try to sell you a "rebuild kit" when they sell you new tires, as they don't want you coming back complaining about leaky valve stems. The kit will include a new valve core, a new retaining nut, and a new seal for the stem itself. This is fine, it your car is fairly new, and the TPMS batteries are still probably good. If the car is older, the TPMS' batteries are probably nearing the end of their life cycle, so complete units are a good, but costly, idea.

Just consider, in the old days, new tires automatically meant new valve stems. Today, it's a little more complicated (and expensive), because the "nanny state" thinks we don't know how to use a tire gauge, so they mandated TPMS....

Is Tech II a device that is readily available? I would rather monitor my tire pressure the old fashioned way. If I go with conventional valves and can't program out the DIC warning I guess I could live with the minor annoyance as long as it didn't affect anything else. Thanks, Bob

 

The Tech II is primarily a dealer tool, but if you really wanted one badly enough to spend the money (serious $$), they pop up on E-bay sometimes, and you can get a bargain.

 

Now is the time to replace them.

 

I would suggest you program the TPMS sensors before you have the tires mounted. Follow the programming instructions from DeeGee from the driver's seat, just mark each sensor LF, RF, RR, LR as appropriate (I used a Sharpie) as you program it and have the installer put them with the correct wheel. It's much easier for the magnet to activate the sensor this way.

 

That is great thinking, thanks very much. Bob

 

[QUOTE=bigbob76;1582886703]A lot of people don't have working sensors. You can just hit reset when you get the service message which will be each time you start the car. It will not effect anything else.

 

[QUOTE=BigGun;1582898146]Thanks BigGun, that is good information to have while shopping for tires.

 

How do you do this --- put each sensor by each wheel then move the maganet around, wheel by wheel, as the computer addresses each wheel? Won't the computer be trying to activate the sensor still in the wheel or does the computer only see the sensor with the maganet on it.
Once I program/activate the new TPMS will the old ones in the wheel no longer work (they are working now but 10 years old)?
