Can l use only working electrode and a counter electrode for measuring the electrochemical impedance without a refrence electrode?

I tried to measure the EIS of my photocatalyst by using only a working electrode (my catalyst was dip dropped on FTO) and a counter electrode (Pt), but most of the times it showed a high impedance...
