How to Clean the Pressure Sensor of the Fiat Seicento

Model: Fiat Seicento MK 1 - Years 1998-2010
Part: MAF sensor

If the engine shows performance issues, struggles to accelerate, and excessive fuel consumption is noted, it is likely that the pressure and temperature sensor of the intake air is providing incorrect data to the engine management unit. Before replacing it, try cleaning it with contact spray and brake cleaner. The sensor is located beside the throttle body on the engine. Once the bonnet is opened and the air filter box is removed, locate the pressure sensor, disconnect the connector, and unscrew the fixing screws to extract it from its housing for cleaning, avoiding blowing with compressed air. Then proceed in reverse for reassembly.
