Find out how the powertrain control module (PCM) affects your car's operation and whether overheating can occur due to a faulty PCM.

Essentially, the PCM combines the roles of the Engine Control Unit (ECU) and the Transmission Control Unit (TCU), providing centralized control over the vehicle's powertrain to ensure optimal performance, efficiency, and emission control.

Both components are involved in the engine's operation, the intake manifold deals with air distribution (and sometimes fuel), while the fuel rail deals specifically with delivering pressurized fuel to the injectors.

The Mass Air Flow (MAF) sensor is a critical component in modern fuel-injected engines. It measures the amount of air entering the engine's intake system and sends this information to the engine control unit (ECU). The ECU then uses this data to calculate the correct air-fuel mixture for combustion.

Traction control is a vehicle safety feature designed to prevent wheel slip and loss of traction during acceleration by modulating engine power and/or applying brake force to individual wheels. 

The ECT sensor typically utilizes a thermistor, which changes its resistance based on the temperature of the coolant. As the temperature changes, the resistance of the thermistor changes, allowing the ECU to measure the temperature accurately.

The car air filter is a critical component of your vehicle's engine system. It's responsible for filtering the air that enters the engine, removing dust, dirt, debris, and other contaminants before they can reach the combustion chambers. 

A Mass Air Flow (MAF) meter, also known as a Mass Air Flow sensor (MAF sensor) or simply a mass air meter, is a device used in the air intake system of internal combustion engines to measure the mass flow rate of air entering the engine. It's a crucial component of modern electronic fuel injection (EFI) systems.

The primary purpose of an Electronic Fuel Injection (EFI) system is to precisely control the amount of fuel delivered to the engine cylinders for combustion. Unlike carburetors, which rely on mechanical principles to mix air and fuel, EFI systems use electronic sensors and control units to optimize fuel delivery based on various engine parameters such as engine speed, load, temperature, and throttle position.
