Is your fuel consumption not making any sense at all? If you've just taken your ride to the mechanic for a tune-up and still do not get the miles-per-gallon and engine performance that you're expecting, then maybe your MAP Sensor has already gone bad. The manifold absolute pressure (MAP) sensor is designed to continuously compare atmospheric absolute pressure to the intake's manifold vacuum and then relay the apt voltage signal or frequency to your vehicle's onboard computer. The computer measures engine load and subsequently advances or retards the ignition timing based on such information. If your MAP Sensor goes bad, it will drastically lower your vehicle's miles-per-gallon and engine performance. The best remedy here is to have your MAP Sensor, your vacuum hose, and your engine checked for possible leaks or problems. If both your engine and your vacuum hose are okay, then it's most probably your sensor that causes the troubles. Thus, replacing it with an OE part will be your best option to address the issue.
