CV joint (Constant Velocity Joint) is a mechanical component used in front-wheel drive, all-wheel drive, and some rear-wheel drive vehicles. It allows the transmission of power from the drivetrain to the wheels while accommodating changes in angle and maintaining a constant rotational speed.

Types of CV Joints:

• Outer CV Joint – Connects the drive shaft to the wheel hub and allows movement in multiple directions for smooth turning.
• Inner CV Joint – Links the drive shaft to the transmission, allowing flexibility as the suspension moves.

Functions of a CV Joint:

• Enables smooth power transfer even when the wheels turn or move up and down.
• Reduces vibrations and enhances driving stability.
• Prevents excessive wear on the drivetrain components.

CV joints are typically protected by CV boots, which contain grease to keep the joint lubricated and prevent dirt or moisture from causing damage. A damaged CV joint can lead to clicking noises, vibrations, and poor handling.

Auto Sensor (Automotive Sensor) refers to an electronic device used in vehicles to monitor various parameters and provide data to the car's control systems for optimal performance, safety, and efficiency.

Functions of Auto Sensors:

• Collect real-time data on engine, braking, fuel, and environmental conditions.
• Send signals to the vehicle’s ECU (Electronic Control Unit) for adjustments.
• Improve performance, fuel efficiency, and safety.

Common Types of Automotive Sensors:

• ABS Sensor (Anti-lock Braking System Sensor) – Monitors wheel speed to prevent wheel lock-up during braking.

• Oxygen Sensor (O2 Sensor) – Monitors exhaust gases to optimize fuel mixture and reduce emissions.
• Throttle Position Sensor (TPS) – Detects the throttle valve position to regulate acceleration.
• Crankshaft Position Sensor – Tracks crankshaft rotation to ensure proper ignition timing.
• Camshaft Position Sensor – Helps control fuel injection and valve timing.

• Air Filter – Prevents dust, dirt, and debris from entering the engine, ensuring clean airflow for combustion.
• Oil Filter – Removes contaminants from engine oil, keeping it clean and improving engine performance.
• Fuel Filter – Filters out impurities from fuel before it reaches the engine, preventing clogs and damage.
• Cabin Air Filter – Cleans the air entering the vehicle's cabin, removing dust, pollen, and pollutants.
• Transmission Filter – Filters out debris from transmission fluid, ensuring smooth gear shifts and prolonging transmission life.
