Tjaa, mahtoikohan MAP-anturi hajota Audista ku työpaikan pihalta ei startannu ekalla yrityksellä lainkaan, toisella sitten lähti käymään mutta tehot tyystin kateissa... -05 3.2 FSI quattro kyseessä siis... edit. Symptoms of a Bad or Failing Manifold Absolute Pressure Sensor (MAP Sensor) Excessive fuel consumption.

Excessive fuel consumption A MAP sensor that measures high intake manifold pressure indicates high engine load to the PCM. This results in an increase of fuel being injected into the engine. This, in turn, decreases your overall fuel economy. It also increases the amount of hydrocarbon and carbon monoxide emissions from your vehicle to the surrounding atmosphere. Hydrocarbons and carbon monoxide are some of the chemical components of smog. 2. Lack of power A MAP sensor that measures low intake manifold pressure indicates low engine load to the PCM. The PCM responds by reducing the amount of fuel being injected into the engine. While you may notice an increase in fuel economy, you will also notice that your engine isn’t as powerful as it was before. By reducing the fuel into the engine, combustion chamber temperatures are increased. This increases the amount of NOx (oxides of nitrogen) production within the engine. NOx is also a chemical component of smog.
