Indirect Tire Pressure Monitoring Systems – Making a Comeback
Indirect Tire Pressure Monitoring Systems (TPMS) are the systems that don’t have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly. Older indirect TPMS are not as sensitive to
10 Toughest Cabin Air Filter Jobs
Cabin air filters prevent leaves, dirt, bugs and other debris from entering the HVAC system. This prevents the fan and control doors from jamming with debris that could cause fan noise or affect the operation of the heater, air conditioner and defroster.

The Inner Workings of Variable Valve Timing Technology
Variable valve timing (VVT) is a way to advance/retard valve timing, and change duration, overlap and even lift in some applications while the engine is running. VVT is computer-controlled and typically uses oil pressure to change the position of a phaser mechanism on the end of the camshaft to advance or retard cam timing. VVT
