Answer

$E_y = 0$

Work Step by Step

By symmetry, the +y component of the electric field at $P_1$ due to charges on the rod which are below the x axis cancels out with the -y component of the electric field at $P_1$ due to charges on the rod which are above the x axis. Therefore, at $P_1$: $E_y = 0$
