1996 Accord EX check engine - ect sensor low voltage
 

My check engine light has been on for almost a year and the code that comes up is engine coolant temp sensor. I have replaced both ect sensors and the code still comes back on after the drive cycle.
I can't pass emissions with that check engine light on and my registration was up in February so I need to get this fixed asap.
Does anyone know how to fix this or what the problem actually is, since both ECT sensors are brand new.
