My E280 doesn't have sensor for speed signal. I wonder how the ECU recognizes the vehicle's speed. Can any one tell me at which pin the ECU receives the vehicle's speed?

I didn't see any sign of fuel starving. It runs as it should until it reaches 4000rpm. Fuel is cut off when above 4000rpm then resumed as long as the car reaches 4000rpm again.
