Can a bad coolant temperature sensor cause a car not to start?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Where is the temperature sensor located in a car?
You car uses a temperature sensor to determine the temperature. In fact, it might use a few. “Most sensors for the in dash readout found in most cars are placed somewhere safe where they can’t be damaged or influenced by engine heat,” says Volkswagen Canada spokesman Thomas Tetzlaff in an e-mail.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
How to replace or reset ambient temperature sensor-car?
You can replace or reset ambient air temperature sensor after removing it. You have to replace it if there is sensor malfunctioning. Or find the reset button on it. There are Mode buttons on the sensor in some cars that allow you to do so.
Why do we need an ambient temperature sensor?
The sensor plays an important role to make our rides comfortable. It keeps an eye on the car’s cabin temperature. The sensor monitors temperature from inside the car as well as out. An ambient temperature sensor allows the AC or Heater to maintain a normal temperature inside.
Where is the coolant temperature sensor on a car?
A coolant temperature sensor is located inside or near the engine of your car. It measures the temperature of your vehicle’s engine coolant and sends this information to the Engine Control Unit (EUC). This, in turn, shows how much heat your engine is giving off.
Why does your car’s outside temperature sensor always work?
The sensor’s low location puts it close to roadways, which are excellent at absorbing, storing and radiating heat from the sun. When the sun’s energy is blocked or you can get enough fresh air rushing over the sensor, that’s when you’ll get a more accurate reading of the outside temperature.
What are the signs of a bad temperature sensor?
Common signs include a faulty AC auto mode, inconsistent cooling, and incorrect outdoor temperature readings. 1. The AC auto mode will not work 2. Inconsistent cooling 3. Incorrect reading on temperature gauge
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
While it may not be the coolant temperature sensor that is causing your car to not start, it could be a plethora of other issues. One of the most common reasons why a car doesn’t start is that the battery is dead. If this is the case, you can use jumper cables to jump start your car and let it run for a while so that the battery recharges.
What happens when the coolant temperature of an engine goes up?
Engine efficiency, power and fuel economy all improve as the engine temperature rises. Ideally, the engine will run as hot as possible without boiling its coolant or damaging its components. But a faulty engine coolant temperature (ECT) sensor can cause havoc on an engine or its related systems.

Where is the coolant temperature sensor located in the engine?
Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations.
