Question about 2007 Jeep Liberty Sport

1 Answer

On the first start of the day if the outside temperature drops a few degrees below freezing the vehicle will start run for 2-3 sec shut down, I've noticing the dash security light is on ( key with a / through it). after several attempts at starting it eventually remains running and dash light goes off. The colder the outside temp the more starts to keep running. So up to now this has only happened a few times a year since new. Note while under warranty dealer found nothing wrong.

I am a chrysler dealership technition and it sounds to me like you have a faulty skim module. it could be that when the electronics are cold it is causing a chip in the module to fail these are not uncommon to fail. if you contact chrysler customer service and complain loud enough they will take care of it.

I have a 2006 audi a4 3.0 when temperature outside drops below 40 degrees it will not start ,when the temperature outside gets around 45 degrees it starts and runs with no problem . screen reads ok


I assume from the question that the engine is cranking over but will not start. Hence there is no issue with the starter motor on a very cold start.

At 40 degrees F you are getting closer to freezing. When this happens again I would check the operation of the fuel pump.
Take the fuel cap off the fuel tank and have someone switch the ignition on and off a few times. (just the ignition - don't start the engine up). Turn it on for 10 seconds or so and then off. If you listen at the fuel filler opening with the cap off you will be able to hear if the fuel pump starts and stops. If it is working it should start and then stop a few seconds later each time you switch on the ignition because the computer shuts it down in a few seconds if the engine is not started.

If the fuel pump is operating I would be looking for some electrical gremlins. You would need to check that the fuel injectors are getting power and that the spark plugs are also.

Ideally you would need to a quality scan tool connected to the car when you have this very cold no start condition whilst trying to start the car to see what faults may be present because it should pick up some malfunction if the start problem goes away when the temp rises a few degrees over 40F.

Another Tip for saving fuel and sometimes correcting hard-starts and other...


Almost all vehicles nowadays are equipped with an engine coolant temperature sensor. They are in place to tell the vehicle's computer (PCM) what the temperature of the engine is at any time. In a lot of cases, it acts like an electronic carburetor choke.

For instance, when the temperature outside is 32 degrees F and the car has been sitting outside long enough to cool down to that temperature, the temp reflected from the coolant temp sensor SHOULD be telling the computer, "Its 32 degrees here inside the engine so dump extra fuel so it can start!" (Kind of like a closed choke on carbureted engines, only no moving parts except for the fuel injectors."

But what if that's not what the coolant temp sensor is reading? What if it thinks the temperature is 200 degrees F inside that 32 degree engine? In this case, it will report to the computer that the engine is already warmed up and minimal fuel will be required to start the vehicle. Hence, a hard or no-start!

A mis-calibrated (worn out) coolant temperature sensor can also cause a lot of driveability issues as well. For instance, if this had been the opposite scenario...The engine is actually 200 degrees F but the sensor thinks it's 32 degrees, this will cause the engine to run extremely rich, throw a light on the dash, and most likely stall out.

In my opinion, the coolant temperature sensor is arguably one of the most important sensors on your vehicle. If it's checked and/or changed regularly (I would change it about every 50,000 miles or so) this will be one of much forgotten steps in providing good fuel economy and good driveability...Not to mention good cold starts when the weather outside is frightful!

The good news about replacing this handy little guy? Two things. Inexpensive and easy to replace! The coolant temperature sensor can be purchased at most (if not all) auto parts stores (depending on your make and model regarding immediate availability.) For example, on a '98 Chrysler Sebring, Auto Zone has the sensors available for $25.99.

You can usually locate your coolant temperature sensor on or near the thermostat housing. (Again, vehicle make and model will vary in some cases regarding location.) It will usually have 2 wires leading to it. If you see a sensor with only one wire, you've found the coolant sending unit for your coolant gauge.

I hope this tip has helped you and I wish you another year of safe driving and good driveability!

My hydroquip cs6230-u pack on my hot tub shuts off for days and comes back on. None of the circuit breakers pop. The cold weather is coming and I don't want any pipes to freeze. I would also like to u


I do not know this unit so this is only a guess on my part.

I am not sure what you are by it shuts off for days. If it is hot that may also cause it to shut down but for less then an hour. The manual can be found by googling:

hydroquip cs6230-u pack manual

Several of the manuals show up. Be sure CGFI is OK.

This is what I found in the manual. Measure your water temperature it may be OK.

FREEZE PROTECTION - There are two(2) levels of freeze
protection integrated into the system.
1 - SMART WINTER MODE, this mode will activate any time the
temperature falls below 59BF. This mode will be active for a period
of 24-hours. In this mode, if a pump has not been activated in the
last 2 hours, the system will automatically turn it on for 1-minute
to prevent freezing. The "Filter Cycle" indicator will illuminate
while this mode is active.
2 - If the spa water temperature drops below 49BF, the heater &
pump will be activated until the water temperature reaches 50BF.
While freeze protection is active no other functions will be
possible.

2003 ford expedition will not crank below 50 degrees. Security light on the dash will flash real fast. motor will turn over just will not crank. later in the day when it warms up it will start right up and...


It can be as simply as a bad battery. The Antitheft system views a low battery as an attempted theft action. Then the Antitheft cuts cranking voltage to around 7 Volts to prevent the engine from starting.

Battery voltage drops in cold weather. This would explain your problem and the activation of the Antitheft light.

Please rate my info. You might try adding a battery charger for a few minutes before you try starting it and see what effects it has.

Another idea is to turn off the A/C when cranking. The A/C clutch is a big drag on the system AND is temperature controlled to disengage the clutch at lower outside temperatures. If this control is not working, the A/C would not disengage.

You can get the starter tested on the vehicle with a DRAW test. The battery can be tested too. FREE at most big parts stores like Autozone.

What is the red light that looks like a snowflake


The snowflake appears when the outside temperature drops to 40 degrees or below, it then changes to red when it is 32 degrees and below. It seems the manufacturer thinks this will assist you with your driving habits on frozen roadways.

You could try applying silicone spray on the rubber seals around the window. This usually helps prevent them from freezing and actually cleans and conditions the seals.

'02 Escape, heater cold when outside air below freezing


This could be a few different problems. I would recommend taking it in and having the antifreeze checked to see if it is of a sufficient mix to keep it from freezing. Sometimes the antifreeze will be to thin to keep it from freezing and it will start to freeze in the heater core. If this is the case, the vehicle may not run long enough to thaw out the antifreeze in the heater core to generate heat. Another possibility is that the thermostat is stuck in an open or partially open position not allowing the engine to reach a high enough temperature to generate heat through the heater core. The last possibility is that there is a blockage in the heater core not allowing the hot antifreeze to pass through the heater core thereby reducing the amount of heat drawn off of the heater core. These are but a few of the more simple problems but any of them should be treated by a licensed mechanic.
