The nonbinding move was initiated by Prime Minister Viktor Yanukovych's Party of Regions.
Lutsenko was a leading force in the mass street protests that helped Yushchenko defeat Yanukovych in the rerun of the 2004 presidential election. He has led high-profile corruption investigations against Yanukovych's allies.
The proposal to suspend Lutsenko came two days after parliament accepted the resignations of another two Yushchenko allies from the government. They had asked to step down after Yushchenko's Our Ukraine bloc said it was moving into the opposition.
