C0379 C0374 C0359 C0327 C0321 C0306 C0305 C0300.

My car has 178000 miles.
My car has an automatic transmission.

Hey there. If the codes are cleared with a scanner, check to see if they return. Maybe the system was serviced or the battery ground is loose and causing the circuit to break which could cause a lack of communication between some components. If you would like having this checked, a qualified professional from YourMechanic can come to your car’s location to throughly inspect the car to pinpoint underlying causes for the codes.
