The problem is most likely on the transmission range selector switch, this is on th top of the transmission and has a multi-wire connector going to it, a shaft goes through it and the trans shift cable is connected there.

Take the car back to your Mechanic and have the mechanic reset your system. Some may advise you to disconnect the battery, and that will reset your computer. This may cause significant problems with your car's computer,radio, alarm. Take the car to the mechanic.

1174 is a lean code, and would have to been set first because it will not set when the 0300 is there. 0300 is a random misfire, because it read after the lean code, it was probably caused by the lean condition. 1st check for vacuum leaks from hoses or intake gaskets, you cal listen for a hissing sound, or spray carb cleaner around intake systems, a change in rpm will be noticed when spraying near a vac leak. other probable causes are the upstream 02 sensor, map sensor, or fuel delivery problems. does the vehicle idle porly, or does it miss at the top end?

I had the SAME problem...do you smell any fuel smells? Is your car getting less MPG and is does it have less excelleration? It is the Fuel Injector(s)...
Most likely...one or more has gone bad, I believe this is yet another common problem with the Saturn ION...hhhhmmmm I wonder why they went out of business...

When this happened to mine it ended up being a bad door switch. The alarm, dome/map lights and electric door locks are all connected to the door switches. It cost $65 for diagnosis, parts and labor at Saturn of South Burlington VT

Evaporative Emissions (EVAP) Vent System Performance
The EVAP system tests run when the engine is first started and meets the Conditions for Running the DTC. An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill condition.An EVAP canister, vent hose, or vent solenoid valve that has restricted flow may cause this DTC to set. Using a purge solenoid command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the engine running, the EVAP canister vent solenoid valve open and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 5 inches H2O.An EVAP canister filter that is restricted can cause this DTC to set. Refer to Evaporative Emission (EVAP) Canister Filter Replacement and Evaporative Emission (EVAP) System Cleaning .Disconnecting one component at a time while the EVAP system is under flow will help to pinpoint a restriction in the system.Reviewing the Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.For intermittent conditions, refer to Intermittent Conditions .
