No, the sensor on a focus is a variable reluctor. The only car with the speedo transducer the same as the puma is the mk5 fiesta and possibly KA. At a guess id also say if there was a mk5 1.6 digi dash escort it should fit. First check the 3 pin plug that connects the transducer to the loom, it may have just come out. If all is well and the unit itself is goosed, speak to Ian G off here and he will send you a known working good part to replace it with. Im pretty confident he can beat £150 :lol:
