Is your Daihatsu Mira (TA-L250S with the EF-SE 3AT engine, 2005 model year) running rough, getting poor fuel economy, or throwing a check engine light? It might be the MAP (Manifold Absolute Pressure) sensor. This X AUTOHAUX part is a direct replacement for OE numbers 89421-B2010, 89421B2010, and 9020. It's a 4-pin sensor, about 5.3 x 4 x 4 cm in size, that monitors the air pressure in your intake manifold and sends that info to your car's computer. A good sensor is crucial for proper fuel mixture and engine performance. This one is built with a quality sensor chip designed to match the original for easy installation and reliable service life. PLEASE double-check your vehicle year, make, model, and engine, and compare the pictures with your old part before buying to ensure a perfect fit. This is a non-OEM aftermarket part, but it's a cost-effective way to get your Mira running smoothly again.
