Hi, it sounds like you are having a few issues with your car. The P0117 code you received is the coolant temp sensor failure. Although your gauge is not reading high, with the coolant temp sensor failing, the gauge will not register an overheating issue. Your first step would be replacing the coolant temp sensor. Then you would want to have the vehicle block tested in order to ensure the head gasket is not leaking. If you need help, YourMechanic offers a repair and diagnosis service preformed by a certified mechanic that will commute to your location to inspect your trouble codes and overheating issue.

The most obvious sign of an overheating engine is a rising temperature gauge, especially if the check engine light also comes on. Smoky steam coming from under the hood means that the coolant has bubbled out of the radiator and that you need to pull over immediately – or major engine damage may occur.
The most common reasons a Nissan Altima is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Cooling System Leaks: The most likely of reasons a car would overheat is a cooling system leak. Over time, cooling system components like the radiator, hoses, water pump, head gasket, and thermostat housing can become worn by high heat and pressure, making them prone to leaks.
An overheated engine is very often caused by cooling system failure. The cooling system draws heat away from the engine — where the combustion chamber can reach 4,500 degrees Fahrenheit — and pushes it to the outside. If something is wrong with the cooling system, such as a leak, then your car can overheat.
That said, a severely overheating engine can cause the cylinder walls or the pistons themselves to warp, bend and deform. This will cause the perfect seal between the piston and the rest of the engine to lose integrity. Oil could be forced past the piston rings and into the engine, where it will burn the oil.
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
As the engine heats up, the thermostat gradually opens, allowing coolant to reach the radiator. Whenever it begins to fail, the engine overheats and, if the problem is left unchecked, leads to your engine boiling over. This can lead to costly repairs.
Wait until the gauge moves back to the normal range or the light extinguishes before you open the hood. DON`T wait for it to get better on its own. An overheating engine won`t repair itself, and you should bring your car in to Jiffy Lube as soon as you can.
The P0217 code means that the engine is or was overheating and should be turned off as soon as possible.
How long can a car overheat before damage occurs? It only takes 30-60 seconds of overheating for permanent damage to infiltrate a vehicle. As soon as you notice signs of overheating, you need to act. Failure to do so might result in troubles like coolant leaks, damaged radiator caps, and a faulty cooling fan.
COOLANT TEMPERATURE SENSOR FAULTY: SYMPTOMS
Higher idle speed. Increased fuel consumption. Poor starting behaviour.
Look to see if the coolant is swirling/flowing immediately — that means the thermostat`s stuck open. If the coolant doesn`t flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it`s hot, the thermostat`s likely stuck closed. Replace the radiator cap and turn off the engine.
If it gets hot at all times, then it may have a clogged radiator, or more commonly a leaking head gasket. I would perform a block test prior to changing anything else. If that fails the test, then the engine will need to be disassembled and repaired. If it passes, then it may need a radiator.
The most common reasons for your car temperature gauge going up but not overheating are due to temperature sensor failure, a broken temperature gauge, engine control unit failure, corrosion in connectors, or damaged wires feeding to the sensor or gauge.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
One of the first things you will notice is the temperature gauge is higher than normal. It may even start to fluctuate frequently. If you notice the gauge is hovering ¾ of the way from the top, then your thermostat is experiencing damage in the form of overheating. This can soon lead to your engine and car overheating.
As soon as you notice an issue with your vehicle, the next course of action is to pull off the road to a safe and clear area and turn off the vehicle. If the vehicle is overheating, continuing to drive with a potentially damaged engine may cause permanent damage.
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
If you notice that your engine overheats, the coolant temperature sensor could be the problem. At times, the coolant temperature switch may fail such that it starts transmitting hot signals permanently. This causes the computer to erroneously counterbalance the signal, thereby causing the engine to misfire or overheat.
The furthest you can drive an overheating car is about a ¼ mile before you risk irreversible engine damage. While some vehicles could still make it as far as 20 miles, we would never recommend driving very far with an overheating engine.
Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
Loud popping, knocking, and stuttering noises from the hood of your vehicle are cause for concern, and could be a sign of major engine damage.
