p1309 is misfire detection monitor.
does the engine misfire? can you feel that it shakes more than i should?
did you recently run out of fuel?
did they replace the spark plugs and wires?
were your fuel injectors used from your old motor?
was the cam position sensor replaced?
most likely it is the CMP check and make sure it is connected, it is in the rear of the motor behond the intake closer to the passenger side, it looks like the bottom of a distributor with no cap and rotor on it. if it is, have someone clear the codes, disconnect the battery, turn the headlight switch to on, and then to off, and leave it sit about 15 mins then reconnect. See if it comes back on as the same code
