Hello, I am working on a 2004 Saturn Ion2, and there is 4 check engine codes that I need help with: “p0455 p1351 p1352 p0420”. Also, the car smokes a white/grey cloud sometimes when starting only. the spark plugs are white also. What should I do/check first? Any help is GREATLY appreciated!! Thanks!

DTC P1351 Ignition Coil Control Circuit High Voltage
DTC P1352 IC Output High/Pulse Detected when GND_Cyl. 2
DTC P0455 Evaporative Emission (EVAP) System Leak Detected
DTC P0420 Catalyst System Low EfficiencyThose first 2 I’d be concerned with figuring out first, assuming they come back and aren’t flukes. The plugs, that’s likely indicating a lean issue and/or timing problem. If the smoke you’re referring to goes away in a couple seconds it’s likely just burning out condensation on start-up, if longer, you might have an oil burning issue, rings, or possible PCV stuck closed.
As to where to start for those 2:

Were it me, I’d probably be hard looking at the ICM, it’s ground first off.
