Analog Input Fault

I am currently having an issue with an analog input AN8, It constantly shows a voltage in PC link of 5.5 volts. This remains the same regardless of whether I have it connected or not. It is reading the position from an actuator valve which outputs 0.5V to 3 Volts. I have back-probed the Input where is connects to the ECU (white/Yellow wire)  and it reads correctly on a multi-meter. Any suggestions on where to start?
