We study the motion of particles in the background of a scalar–tensor theory of gravity in which the scalar field is kinetically coupled to the Einstein tensor. We constrain the value of the derivative parameter z through solar system tests. By considering the perihelion precession we obtain the constraint 
m, the gravitational redshift 
m, the deflection of light 
m, and the gravitational time delay 
m; thereby, our results show that it is possible to constrain the value of the z parameter in agreement with the observational tests that have been considered.
