If that's the interpretation of the code given to you after the scan, then that is the only thing to work on.

Good luck.

Trouble codes p0118 temperature po118


code p0118 refers to engine coolant temperature (ETC) sensor ---circuit malfunction===causes---coolant thermostat---wiring open circuit/short to positive---wiring short to ground---ground wire defective---ECT sensor.. The temp gauge works off a temperature sender unit separate to the coolant sensor and if it is reading 100 then it indicates an overheat situation in the engine . Probably why the engine light is coming on. As the thermostat is in the list of causes I would replace it as a precaution. The coolant sensor is what tells the CPU to turn on the electric fans to cool the radiator

'low coolant light' flashes all the time and then 'service engine soon'


These problems may or may not be related. The Check coolant light means that the coolant level in your radiator is low. If you have checked it and it is not low, then the sensor is most likely defective. The low coolant sensor will not turn the Check Engine light on - even if the coolant really is low. There are many things that can cause the Check Engine light to come on. You will have to scan your Engine Computer to find out why it has been turning the light on.

I did have a problem on one of these cars one time where the Check Engine light was coming on and there were several codes for the Throttle Position Sensor(TPS) and the Manifold Absolute Pressure (MAP) sensor and the car ran really bad. The Check Coolant light was also on. After checking it out I found that the coolant level sensor was shorting out the 5 volt reference circuit (VREF) from the computer and causing the whole problem. Replacing the coolant level sensor fixed the car.

Check engine light code on for engine coolant


Check continuity of the sensor wire. It should run between pin #4 (check manual (chilton better than haynes for electrical) for location as sometimes there are design changes) of the black harness plug on the computer to the sensor. The other sensor wire is shared with the cps and tps sensors, so if you don't see problem readings with those that wire is likely good.
Also, make sure that you have no air in the cooling system or as it passes the sensor it can mess with the readings. Run the engine with the system open and the heat on high....I like doing this with the front of the vehicle either jacked up slightly or pointing up-hill... run a complete "cycle" from cold to operating temp and add coolant as needed.
Hope this helps!

I HAVE A 2007 CHEVY COBALT THE CHECK ENGINE LIGHT CAME ON I CHECKED THE COOLANT TEMP GAUGE THE DIGITAL GAUGE READING WAS ONLY SHOWING THREE BROKEN LINES. I CHECKED COOLANT LEVEL WHICH WAS FINE. ENGINE DID...


I had this problem with a 2007 Chevy Cobalt. I changed the coolant sensor and even though the check engine light went out I still had a reading of "---" on the coolant gauge. The problem is most likely one of three things: a low coolant level, a bad coolant sensor, or the thermostat needs to be replaced. The only other possible thing it could be is a bad BCM (Body Control Module) which in that case you would most likely be having other weird problems.

The Thermostat and the sensor are both very easy to get to and replace. Take off the engine cover by removing the oil cap and they are both to the rear of the engine on the driver's side. They are right next to each other.

Hope this helps!

Check engine light, not registering temp


Hi, You'll need to get the trouble codes read. I'm guessing the code probably has something to do with your engine coolant temperature sensor or the engine coolant temperature sending unit.
