My fiances car has code 12 and 43, can anyone help me eith what these mean?
also where does her coolant go?? it seems to be leaking somewhere but not on the garage floor. its a mystery, any help will be welcomed

thank you!!

sorry codes 13 and 43

The Code 13 is for the MAP sensor. Check the wiring and clean it up a bit. THe Code 43 is a single or multiple cyliner misfire. Usually it means it's time to change your spark plugs. Buy some stock copper Champion spark plugs and put them in. Also inspect the coil pack and spark plug wires for any cracks or wear.

The coolant goes in the coolant reservoir on the passenger side of the engine, attached to the firewall.
