1: Understanding the 2014 Jeep Wrangler TPMS

The Tire Pressure Monitoring System (TPMS) in the 2014 Jeep Wrangler is a direct system. After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, were installed with direct or indirect TPMS systems.

Jeep Wrangler TPMS Sensor

1.1: Direct TPMS Explained

Unlike indirect systems, direct TPMS uses sensors installed inside each wheel to measure tire pressure in real time. These sensors transmit data to the vehicle’s ECU (Electronic Control Unit).

1.2: How the System Alerts You

If one or more tires indicate low pressure, the TPMS alerts you in one of two ways:

• Low-Line System: A simple indicator light illuminates on the dashboard.
• High-Line System: Each tire’s individual pressure is displayed on the dashboard.

1.3: TPMS Sensor Replacement and OBD Relearn

When a TPMS sensor is replaced, an OBD relearn procedure is recommended. This process writes the new sensor IDs to the vehicle’s ECU, ensuring accurate pressure readings and alerts. According to the National Highway Traffic Safety Administration (NHTSA), proper TPMS function is crucial for preventing accidents caused by underinflated tires.
