Hi,

The P1388 isn't a good sign, normally it points to a bad PCM. Do you have any symptoms to go along with the light? Has it stalled out recently? Running funny?

The P0545 isn't one I'm familiar with and it doesn't show up on any of the trouble code charts for this vehicle. You're certain that's the correct number?
