Hello everyone. I have an issue I need a little input on. After returning from the C5/C6 Bash in Bowling Green and doing a lot of spirited driving including 5 runs at the strip, I am now getting a low tire pressure message on the DIC on the RR tire. Says pressure is low but I have checked the pressure and it is at 30 plus, where it should be. The car is an 2002 coupe with 23,000 miles. What are the symptoms of the sensors failing? I have read these sensors have a battery in each sensor, is that correct? Could the battery be failing in the RR? What is the cost for a new sensor or can the battery be replaced? Any input would be appreciated. Thanks

The batteries in the sensors are suppose to last 8-10 years. The sensors for the 01-04 can be found for $40-50 each. Gene Culley over at gmpartsdirect has cheap prices.

As far as telling if one is bad or not I have no idea. I can check my manual when I get home and see if it shows a way to check them.

 

I would do the re train TPS before I went to the trouble to replace a sensor that may not be bad.

 

Check all your tire pressures, they may be out of position.

 

I agree that you should first try and retrain the sensors and see if that solves the problem. If it doesn't, luckily you have the less expensive type of sensors - can be bought very reasonably from GMPartsHouse.

And yes, they do have a battery in them that over time can go bad.

 

I would just replace them all at the same time.

 

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

 

I just had new tires put on yesterday @ discount tire. I had them use my TPS in my new rims. They told me they rebuilt them also for me at no charge since I spend $1200+ on new tires.

I was under the assumption that these could not be rebuilt but maybe worth a try

Highly unlikely. GM dropped the price can get for 50.00 at the local GM dealer without the nut. Not back at all.

 

They are not rebuildable ( at least not without a lot of work to change the battery)

At most their rebuild consisted of changing the O-ring.
