Tire Pressure Monitor (TPM) System

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1996 Chevrolet Corvette, 1995 Chevrolet Corvette, 1994 Chevrolet Corvette, 1993 Chevrolet Corvette, and 1992 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The Tire Pressure Monitor (TPM) system may also be referred to as Low Tire Pressure Warning System (LTPWS).

The Tire Pressure Monitor (TPM) system is available to continuously monitor the air pressure in each road tire (excluding the spare tire) while the vehicle is being driven. The TPM system also includes a self-check feature that monitors the system's components.

The TPM system consists of a sensor mounted on each of the 4 tires (strapped around the wheel, inside the tire), and a receiver/control module. When a tire pressure falls below 25 psi (172 kPa) after the vehicle has been driven about 30 seconds over 25 mph (40 km/h), a pressure switch within the sensor is activated. An electronic signal is transmitted to the receiver/control module, which will illuminate the LOW TIRE PRESSURE warning light and store a diagnostic code for that ignition cycle.

The receiver/control module also receives diagnostic signals from the wheel sensors. If one or more sensors do not send this signal during the diagnostic cycle, the receiver/control module will illuminate the SERVICE LTPWS warning light and store a diagnostic code.
