This component of the engine block has the role of measuring the mass of air inside the engine block, making it possible to increase the performance of the engine block. If this sensor ever has a problem, the injectors will no longer inject the correct amount of fuel. The consequence: a loss of power.
Air compression malfunction
Whether it concerns a compressor or a turbo compressor, the problem will be quite the same. the role of the compressor is to project the air into the engine block of the Renault Grand Scenic 3.
