    I wouldn't replace it unless there is more determination the motor does not have a knock, they normally don't go bad. As tpenfield said the 5V is a critical reference point for the ECM, if it's off so is every other reading it gets. To find the sensor that is drawing to much current disconnect...

    2008 Chaparral 275 SSI 8.1 Volvo Penta GXI-J Soft Alarm Issues

    If there actually is a knock being sensed then that is an issue. Look for the sensor on the side of the block, will have a singal wire and larger plastic type connector Follow the wire and make sure it is not in a bundle with the spark plug wires. The plug wires if they are side by side will...
