•  The APP sensor is a double contact less inductive sensor.

•  For safety reasons, the APP sensor consists of two sensors.

•  If the APP sensor malfunctions when the vehicle is in operation, a fault code will be stored in the PCM.

•  If one of the sensors of the APP sensor fails then the engine runs with reduced power. However, it is still possible to reach top speed.

•  If the vehicle is equipped with driver information system, the fault message: “REDUCED ACCELERATION” will be displayed.

•  If the APP sensor fails completely then, after a single operation of the BPP switch and the brake switch and a subsequent comparative plausibility test, the engine is regulated to a maximum engine speed of up to 1,200 rpm. The vehicle can be accelerated to a maximum speed of 56 km/h {34.7 mph}.

•  If the vehicle is equipped with a driver information system, the fault message: “LIMITED TOP SPEED” will be displayed.

•  If the vehicle is not fitted with a driver information system, the engine system fault warning light will come on to indicate a system fault.
