The ethics commission of Correa's Alianza Pais (AP) announced one-month suspensions for the three legislators who had advocated decriminalizing abortion for rape victims.
AP official Galo Mora said the three lawmakers -- Paola Pabon, Gina Godoy, and Soledad Buendia -- would be replaced for one month by alternates.
"The sanction is based on a failure to comply with express agreements which were reached with fellow legislators," Mora said.
Ecuador law only allows for abortion when the mother's life is deemed to be at risk or in the case of women with mental disabilities who have been raped.
Correa has been staunchly opposed to any relaxing of Ecuador's abortion laws, branding AP members "treacherous and disloyal" earlier this month for seeking to ease the legislation.
Correa, a devout Catholic and former missionary, has threatened to resign if the country's abortion laws are eased.
