Are TPMS sensors for 1997-2000 Chevrolet Corvette C5 models still available in 2024?

Yes, TPMS sensors for the 1997-2000 C5 Corvette are still available, though the landscape has changed recently. The early C5 sensors are notoriously more expensive than the 2001-2004 versions, and the exact OEM replacements have become difficult to source.

Here is what you need to know about your current options:

The Schrader Replacements (and the Programming Catch) For years, the go-to direct replacement was the Schrader 28006, but it is now virtually impossible to find in stock at major retailers ¹. Schrader replaced it with part number 29178.

There is a major difference in how these sync to the car. The original sensors and the older 28006 replacements were triggered using a strong magnet over the valve stem. The newer 29178 sensors cannot be programmed with a magnet; they require a dedicated TPMS activation tool ¹¹. Fortunately, you can buy a generic GM relearn tool (like the EL-50448 or VXDAS) online for around $10 to $15.

Aftermarket Alternatives If you want to avoid the high cost of the Schraders, there are a couple of proven alternatives:

• ITM Sensors: Available online for around $140-$160 a set. These use a pressure-drop method to sync—you put the car in learn mode and drop the tire pressure by 10 psi to trigger the sensor ⁸.
• TPMS247 / Universal Sensors: Many owners have had success ordering pre-configured sets from specialty sites like TPMS247 or using universal sensors (like part # 33700) provided by tire shops ⁵.

The 2001-2004 System Upgrade If you don't want to deal with the scarcity and high price of early C5 sensors, you can retrofit the later 2001-2004 TPMS system into your car. This requires sourcing a used 2001-2004 keyless entry module and doing some minor rewiring. It is a bit of a project, but it allows you to use the significantly cheaper late-model sensors and greatly improves your key fob range ¹.

Garage Tip: Before you pay a shop to mount and balance the tires, put the car in learn mode and trigger all four new sensors while they are still sitting in the box. Label them for their respective corners once they sync. Doing this verifies you don't have a dead battery or defective sensor from the factory, saving you from paying a shop to dismount the tire twice ¹¹.
