ERROR U1064??

loss of communication with DCM, :confused: what's it mean?
also getting a P0157, something about Circut Low Voltage Bank 2 Sensor 2-B.
i've recently found that one of my FLP clamps is broken, could this be causing the error's.?

Loss of communications is a common code. All the Control Modules share the same 10.4kbps serial bus. Just like when a modem drops bits and gets errors, so does the car's communication system. The codes are present for debugging, and unless there is another problem, they can be ignored.

P1057 Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 2: could be related to an O2 sensor (wherever Bank2, Sensor 2 is located: post cat right side?). If your exhaust has been rattling, perhaps the sensor wire is loose/worn (or a bad sensor?)?

There's a really nice article about C5 computer systems on page 24 of the Spring 2003 Corvette Quarterly.
