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.

Inside Import Car Collision Warning, Automatic Braking Systems

Anything that moves under its own power also has to stop, so brakes have been a safety feature on cars since day one. Over the years, technical innovations such as antilock brakes (ABS) have ­improved the ability to stop with minimal skidding on wet or slick surfaces. The addition of stability control allowed each wheel

Modern Fuel Control Diagnostics: Sorting Through the Datastream

When confronted with a fuel control problem on a modern vehicle, I’ll normally use short- and long-term fuel trims to determine if the problem is caused by one of many failures such as a vacuum leak or a leaking fuel pressure ­regulator. If you’re like me, you’ll occasionally access the air/fuel ratio (AFR) sensor serial

Kia: Added Grounds Can Set Codes

Additional grounds can typically benefit a vehicle’s electrical system. That is, unless the vehicle is a 2008-to-present Kia equipped with a battery sensor. If an extra ground cable is installed on the negative battery terminal, it can cause the battery sensor to send incorrect information to the engine control module (ECM), which can generate all
