Hello and welcome to JustAnswer!

The P2302 and 2305 are for the number 1 and 2 ignition coil circuits. You most likely have no spark on cylinders 1 and 2. These codes can be caused by failed coils, loss of voltage to the coils due to a wiring issue, or loss of coil driver. Loss of driver could be a failed driver within the powertrain control module, a short to power, ground or an open circuit on the driver wire. It will take some testing of these circuits at the number 1 and 2 coils to determine what you have going on.

It's only missing on no. 1 what are you calling a driver is this crank sensor and cam sensor?
Expert:  sprinkles08 replied 2 years ago.
At some point you had lost spark on number 2 also but that may not be current.

The driver is what actuates the coil to produce spark. The coil receives ASD voltage on one wire and the driver circuit is pulsed ground by the PCM.
