What Are the Differences Between MAF Sensor and MAP Sensor?

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

In this video, a clear explanation is provided regarding the difference between the MAP (Manifold Absolute Pressure) sensor and the MAF (Mass Air Flow) sensor. Let's focus on the MAP sensor, which measures absolute pressure directly in the manifold.

On the scanner, the pressure is read in kPa or bar (the conversion is decimal, so very simple: 1 kPa corresponds to 0.01 bar); symptoms of failure include evident problems at low revs, with irregular slowdowns and stalling. It gets dirty due to oil vapours passing from the crankcase ventilation system.

The MAF sensor is located between the air filter and the throttle body, measuring the airflow towards the latter, and is read in g/s (grams per second): failure manifests as a loss of power under load, such as during acceleration or uphill, and it gets dirty due to dust and particulates that pass through the air filter.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
