Can a bad coolant temperature sensor cause a car not to start? 

Yes, a bad coolant temperature sensor (CTS) can cause a car not to start, although it is not the most common reason for starting issues. The coolant temperature sensor monitors the engine's temperature and sends this data to the engine control unit (ECU). The ECU uses this information to adjust the fuel-air mixture and ignition timing, which are crucial for a proper start. If the sensor fails, it may send incorrect temperature readings to the ECU, leading to improper adjustments of these parameters, which can prevent the engine from starting.


When the CTS fails, it often causes the ECU to think the engine is either too hot or too cold. If the ECU believes the engine is cold, it might enrich the fuel mixture (like in a cold start), leading to a flooded engine that struggles to start. On the other hand, if the ECU assumes the engine is already warm, it could lean out the mixture, making it difficult for the engine to ignite when it's actually cold, causing a no-start condition.


Additionally, a bad coolant temperature sensor can also lead to other related issues that may contribute to starting problems. For instance, the sensor's malfunction could result in poor fuel efficiency, rough idling, or even stalling. These symptoms, while not directly preventing the car from starting, can make the engine harder to crank and start over time.



In summary, while a faulty coolant temperature sensor can cause starting problems, it is one of several potential causes. Other factors such as battery issues, fuel delivery problems, or ignition system malfunctions could also be at play. Diagnosing the exact problem often requires checking the CTS and related systems to rule out other causes.
