- Mass Air Flow (MAF) Sensor: Measures the amount of air entering the engine. This information is crucial for the engine computer to determine the correct amount of fuel needed for proper combustion.

- Intake Air Temperature (IAT) Sensor: Detects the temperature of the air entering the engine. Colder air is denser, so the engine computer uses this information to adjust the air-fuel mixture for optimal performance.

- Throttle Position Sensor (TPS): Tracks the position of the throttle pedal (how far it’s pressed down). This tells the engine computer how much power the driver demands, allowing it to control engine speed (RPMs).

- Idle Air Control (IAC) Valve: Regulates the engine’s idle speed. It controls the amount of air bypassing the throttle valve to maintain a smooth and consistent idle RPM when the driver isn’t pressing the gas pedal.

- PCV Valve -

The positive crankcase ventilation valve releases exhaust gas and unburned fuel from the engine block into the intake manifold.

All engines allow some exhaust gases, unburned fuel and oil to “blow by” the pistons and collect in the crankcase where it produces sludge if not eliminated.

Separating the crankcase from the intake manifold, which is a source of varying air pressure, the PCV valve maintains the optimal level of vacuum in the crankcase to extract the products of blow-by as well as potentially damaging moisture. Automakers may designate a replacement interval.

The valve is an inexpensive, easily replaced example of the dozens of parts that can elicit a check engine light and associated vexing investigation. It can also be the source of oil leaks.
