Video tutorial

At the beginning of the video, you can check the code for the required mass air flow sensor. To replace the part, you will need a small flat-head screwdriver.

Lift the bonnet and place the appropriate support rod. First, remove the air filter box: it is secured by four simple clips (two on the air duct) that you can open by hand. Once the filter box cover is removed, disconnect the air duct connector.

Then, unscrew the screw holding the clamp and you can extract the section of the pipe containing the mass air flow sensor. Install the new part by reversing the procedure.

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.
