16 Loss of battery voltage. Battery voltage sensor input below 4 volts with engine running.
Knock sensor circuit. Open or short has been detected in the knock sensor circuit.

and there is no code for 48.. unless you mean 47.


What does your battery guage say while its running?

sorry, the fault codes came from the temperature contron unit itself, not the ecu.
