Can a 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.

What happens when a coolant temp sensor goes bad?

Poor Mileage

A faulty ECT sensor can send a false signal to the onboard computer, resulting in an incorrect air-fuel mixture. For example, a faulty sensor can send a signal indicating the engine is cold when it is not, and more fuel will heat the engine quickly.

What sensors can cause a car not to start?

A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. If you have an RPM signal, a bad ignition module or PCM may not be switching the coil(s) on and off.

What does a temperature sensor do in a car?

Your engine coolant temperature sensor (CTS or ECTS) is responible for monitoring the temperature of the coolant flowing through your car's engine and making sure that your coolant levels are balanced.

Does the coolant temp sensor control the fan?

On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it's not working, the fan won't turn on when it needs to, which means the engine might overheat.

Where is the engine coolant sensor located?

In most cars, the primary ECT sensor (ECT sensor 1) is installed near the thermostat in the cylinder head or block or on the thermostat housing. A second coolant temperature sensor could be installed in another part of the engine, or in the radiator.

Can a bad coolant temp sensor cause rough idle?

Can a bad coolant temp sensor cause rough idle? Yes, due to the false signal sent to the car computer, it will adjust the air-fuel mixture. The supplied mixture will not be enough and result in vibrations and shaking at idle or low-speed maneuvers and lead to other strange behavior and loss of engine power.

What does it mean if your car won't start but the lights come on?

Broken or Damaged Ignition

If your headlights can turn on, but your car won't crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.

What does it mean when your car turns on but wont start?

If your vehicle won't start, it's usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you're dealing with a battery or an alternator problem.

Will a crankshaft sensor keep a car from starting?

Issues Starting the Vehicle

The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.

How do I know if my temperature sensor is working?

Submerge your temperature sensor in the hot water and wait a few seconds to let your multimeter take a reading. Write down your reading so you can easily reference it. A hot water reading should give you around . 25 volts.

What does a cylinder head temperature sensor do?

The sensor's purpose is to measure the cylinder head temperature and to signal the vehicle's operator if an engine overheats (that is, if an engine over-temperature is taking place). The engine will be in danger of permanent damage if it continues to run at an elevated temperature.

What sensor controls the temperature gauge?

To troubleshoot your car's temperature gauge, you need to know how it works. The temperature gauge reading starts out as a reference voltage that is sent to the coolant temperature sensor. This sensor is nothing more than a thermistor -- a variable resistor that changes resistance with temperature changes.
