Can a Saturn Ion start in the Cold?
In northern Wisconsin, cold winter weather is a fact of life. My 2007 Saturn Ion starts in weather as cold as -25°F actual temp without fail, without any special treatment. (But not everyone is so lucky.) We have a fleet of trucks at work (both diesel and gas) that run in all kinds of weather.
What happens when you turn the ignition key on a Saturn?
If the battery is known to be fully charged, the Saturn should start. If there is an error in the ignition switch, you will not hear the typical faint “click” when you initially turn the ignition key to the “III” position to crank the engine.
What does the PassLock system on a Saturn do?
The Passlock system is intended to prevent a worn (worn keys use to be about to start any of the earlier model Saturns without any security system) or incorrect key from starting the car. If the proper code is not sent then the BCM will shut down the car for up to 10 minutes.
Where is the fuse on a Saturn ignition?
Open the fuse panel under the steering column by turning the knob on the fuse panel counterclockwise and pulling down on the cover. Locate the fuse for the starter in the fuse panel using the fuse diagram on the underside of the fuse panel cover. Remove the fuse using a fuse puller in the fuse box.
How to fix a bad intake air temperature ( IAT )?
If this does not happen, it means that the internal computer is to blame, and that it is not producing the voltage that the IAT sensor needs to function. To fix a faulty intake air temperature sensor, remove all carbon and oil accumulation. If this does not fix the problem, replacing the unit is the best option. Like it? Share it!
What to do if your intake temperature is 300°F?
If the temperature reading displays -30 to -40°F, the dashboard light should show the code P0113, and if the reading displays 300°F, the dashboard should show the code P0112. If the reading shows a temperature of 300°F, you need to check if the MAF sensor wires are shorted because of the internal copper getting exposed to each other.
What to do if your air conditioner is reading 300°F?
If the reading shows a temperature of 300°F, you need to check if the MAF sensor wires are shorted because of the internal copper getting exposed to each other. Remove all electrical tape to examine the wires and check for signs of damage. Separate the shorted wires and check if the readings turn normal; if not the connector needs to be replaced.

What should I do if my car hard start when cold?
Let the vehicle cool until the engine is cold. Then perform a cold start test. If you encounter the same hard start when cold and the FLEX FUEL DATA reading is back up to 70% or more, your next step is to check fuel pressure. Check fuel pressure. Fuel pressure must be at least 55-60-psi.
Why does my car not start when I Turn on the ignition?
The most common causes are in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). However, the source may also be a mechanical fault (for example, a leaking valve), or faulty components in other systems.
