Electric Power Steering Sensors
Let’s take a closer look at the sensors which make up EPS systems, and how they operate.

Understanding Passive Wheel Speed Sensor Operation
Passive types of wheel speed sensors are still used in many applications so understanding their operation is important.

Top Tire TPMS Tips For Relearns And Diagnostics
The command to turn on the TPMS light might go through an ABS, keyless entry or other module that acts as a gateway.

Tips For Winter TPMS Service
The installation of snow tires can throw a monkey wrench into your service opportunities this winter if you’re not accustomed to dealing with TPMS.

Making Sense Of Steering Angle Sensor Input And Data
Measuring the position angle, rate of turn and force of the steering wheel is critical for Electronic Stability Control (ESC) systems. Scan tools call these Steering Angle Sensors (SAS) and typically display the information in degrees.
TPMS Sensor Battery: Dead Sensors Cause Other Problems, Too
During the initial TPMS phase-in, many warned about what sounded like an impending crisis. It was the “tire guy’s apocalypse,” which sounds dramatic, but that’s the way I remember the situation being characterized. There was worry and paranoia from all sides. Some companies undoubtedly saw it as a marketing opportunity, and helped perpetuate some of the fear and anxiety. The gist I got from the marketing I saw was that changing tires would, as we knew it, never be the same.
