AUTOMOTIVE 101

TPMS doesn’t save fuel itself, but prevents low tire pressure that raises rolling resistance, fuel costs, and tire wear.

Programming TPMS sensors explained: why the TPMS light stays on, OEM vs aftermarket sensors, and relearn basics.

Universal TPMS sensors explained: how they work, why programming matters, and accurate tire pressure monitoring.

Cold weather drops tire pressure, triggering the TPMS light. Learn to distinguish normal temperature effects from leaks, interpret solid vs. flashing warnings, and correctly inflate, reset, or replace sensors for safe winter driving.

TPMS light on after rotation? It’s likely a pressure or relearn issue, not a bad sensor. Check cold pressures against the door placard first. If correct, perform a vehicle-specific relearn. Replace sensors only if one fails communication tests.

Learn the key differences between direct and indirect TPMS and how each system monitors tire pressure for safety.

Learn what TPMS is in a car, how TPMS works on tires, and how it helps maintain proper tire pressure for safe driving.

Diagnose IMRC issues causing codes like P2004, rough idle, or power loss. Learn to test actuators, sensors, and linkages to distinguish mechanical faults from electrical failures. Avoid unnecessary manifold replacements with targeted fixes.

Diagnose TIPM failures in Chrysler, Dodge, Jeep, and Ram vehicles. Learn symptoms, testing steps, and repair options to avoid misdiagnosis and save money.

Learn how to identify positive and negative battery terminals by color, symbols, cable routing, and a multimeter—and connect them safely.

Have you ever wondered what a water pump does in a car? The answer is simpler than you might think: the water pump. Despite its small size, the water pump is an unsung hero in your vehicle’s cooling system.

The CV (Constant Velocity) joint is an important part of the car's drivetrain. It transfers power from the engine to the wheels. It also allows the wheels to move up and down. The joint is located at both ends of the axle.
