This is crucial for safety, fuel efficiency, and preventing tire wear. Monitoring tire pressure helps ensure optimal vehicle performance and extends the life of your tires. According to the National Highway Traffic Safety Administration (NHTSA), maintaining proper tire pressure can prevent accidents and improve fuel economy by up to 3.3%. Regularly checking your tire pressure via the TPMS using an OBD2 scanner helps you stay on top of your vehicle’s health. At CAR-DIAGNOSTIC-TOOL.EDU.VN, we provide the tools and knowledge to make this process seamless.

1.1 Understanding TPMS

TPMS is an electronic system that monitors the air pressure inside the tires. These systems were mandated in the US starting in 2008 due to the TREAD Act. The purpose of TPMS is to alert the driver when tire pressure drops significantly, typically 25% below the recommended pressure. There are two main types of TPMS:

• Direct TPMS: Uses pressure sensors inside each tire to measure pressure. These sensors transmit data to the vehicle’s computer.
• Indirect TPMS: Uses the vehicle’s ABS (Anti-lock Braking System) to monitor tire rotation speed. If a tire’s pressure is low, its rotational speed increases, triggering the system to alert the driver.

Understanding which type of TPMS your Highlander uses will help you interpret the data and alerts correctly. Direct TPMS provides precise pressure readings for each tire, while indirect TPMS is less accurate but still effective for detecting significant pressure loss. CAR-DIAGNOSTIC-TOOL.EDU.VN offers tools that work seamlessly with both types of TPMS, providing comprehensive diagnostic capabilities.

1.2 What is PID in OBD2?

PID stands for Parameter Identification. In the context of OBD2, it refers to a specific code that identifies a particular data point that the vehicle’s computer can report. These data points include engine temperature, RPM, and, importantly, tire pressure. Each PID is a unique identifier that allows diagnostic tools to request and receive specific information from the vehicle’s control modules. Accessing TPMS data through PIDs allows technicians and vehicle owners to monitor tire pressure in real-time, providing immediate insights into tire conditions. This capability is essential for proactive maintenance and ensuring optimal vehicle performance.
