Hyundai Accent Air Intake Fuel Delivery Sensors

The Hyundai Accent is a sub-compact front-wheel drive vehicle produced since 1994 in sedan, hatchback, and coupe versions. Sensors are vital to the powertrain systems of your Hyundai. Hyundai Accent air intake fuel delivery sensors are available if your own parts need repair or replacing.

How do Hyundai Accent’s air intake sensors function?

The air intake sensors in your Hyundai Accent provide the engine computer with real-time air density data. The computer uses this data to calculate the optimal air-fuel mixture ratio for vehicle performance and fuel economy. The computer then signals the injector to inject the proper amount of fuel into the intake manifold to achieve the optimal mixture ratio. In Hyundai vehicles such as the Accent, air intake sensors include the Manifold Absolute Pressure (MAP) sensor, an oxygen sensor, a throttle position sensor, and a temperature sensor.

What is Hyundai’s manifold absolute pressure sensor?

The Manifold Absolute Pressure (MAP) sensor is a pressure sensor in your Hyundai. The MAP measures the absolute pressure of the air inside the vehicle intake manifold and transmits this data to the engine computer as one of the variables used by the computer in the calculation of the optimal air-fuel mixture.

What is the oxygen sensor in the Hyundai Accent?

The oxygen sensor in your Hyundai Accent is located in the exhaust stream of your vehicle and determines whether the air-fuel mixture is running rich or lean. Instead of a direct measure of oxygen concentration, the oxygen sensor measures the difference in oxygen levels between the exhaust and external air. This data enables the Accents engine computer to adjust the air-fuel mixture accordingly to achieve optimal performance and fuel economy for your Hyundai.

What is Hyundai’s throttle position sensor?

The throttle position sensor is mounted on the throttle plate of your Accent and determines the position of the throttle. In your Hyundai Accent, the sensor transmits throttle position data to the engine computer, which uses it for its calculation of air flow and optimal air-fuel mixture.

What is the temperature sensor on the Hyundai?

In the air intake system of your Hyundai Accent, the temperature sensor measures the temperature of the air going into the intake manifold. This data is transmitted to the engine computer of your Hyundai, where it is used in calculations of the air density and optimal air-fuel mixture.

What are signs of a bad sensor in the Hyundai?

If a sensor in your Accents air intake system goes bad, it will transmit incorrect data, or no data, to the Hyundais computer, causing the computer to incorrectly calculate the air-fuel intake mixture. This can have consequences such as poor efficiency, starting troubles, rough running while driving, and even (with a bad throttle position sensor) unintended acceleration while driving. As these symptoms can have several causes, troubleshooting is necessary. Each sensor is usually a sealed unit and requires replacement when it fails.
