Installation & Requirements
The Schrader 20159 requires professional installation and is not recommended for DIY application. After sensor installation, your vehicle must complete a TPMS relearn procedure using an OBD-capable TPMS programming and diagnostic tool. Proper torque settings must be applied during installation: 7 Nm (62 in-lbs) for the valve nut and 0.5 Nm (4 in-lbs) for the valve core to ensure seal integrity and accurate operation.

Frequently Asked Questions
What vehicles does the Schrader 20159 TPMS sensor fit?
The model 20159 is engineered for Saab 9-3 and 9-5 (2008–2012) and Lotus Evora (2010–2013). This sensor replaces OEM part number 13227143 exactly. Always verify your vehicle's specific year and model against the application guide before ordering to ensure you have the correct fitment for your particular vehicle.
Is the Schrader 20159 programmable or preprogrammed?
The 20159 arrives preprogrammed specifically for your vehicle's make, model, and year at the factory. It is non-programmable, meaning you cannot reprogram it for different vehicles or applications. Once professionally installed and your vehicle completes the TPMS relearn procedure with proper diagnostic equipment, the sensor is ready for immediate use and continuous monitoring.
What torque settings should I use when installing this sensor?
Install the valve nut to 7 Nm (62 in-lbs) and the valve core to 0.5 Nm (4 in-lbs) using a calibrated torque wrench. Proper torque prevents overtightening, which can damage the seal and cause leaks, and undertightening, which allows pressure loss. Always reference your vehicle's specific installation guide to ensure correct fastener application and sensor security.
Do I need special equipment or tools to install the Schrader 20159?
Professional installation is required. You will need a calibrated torque wrench (not included), an OBD-capable TPMS programming and diagnostic tool for the relearn procedure, and a tire machine for wheel removal and remounting. This specialized equipment is essential for safe installation and proper system relearn functionality on your vehicle.
What is included with this TPMS sensor?
The Schrader 20159 package includes the preprogrammed sensor unit, mounting hardware (grommet and nut for clamp-in installation), a replacement valve cap, and a replacement valve core. All components needed for the sensor itself are included. However, you will need external tools such as a calibrated torque wrench and TPMS diagnostic scanner for professional installation completion.
