This could result in hot coolant spraying onto you while you work. If the engine is warm, the coolant could be hot and pressurized. Before removing the coolant temperature sensor, make sure the engine has been turned off for a while.Here are the steps you'll need to follow to replace your coolant temperature sensor. The sensor can be replaced at an auto shop, or you can choose to do it yourself if you're confident in your repair skills. 1) Replace the Corroded SensorĪ bad coolant temperature sensor can't be repaired, but fortunately, a replacement isn't expensive. Let's look at how to fix the two different causes of a bad coolant temperature sensor. However, if the problem is with the electrical connections, you will either need to replace the sensor or repair the wiring problem. If the sensor is corroded or damaged, it will need to be replaced. The steps you will take to fix your coolant temperature sensor will depend on what is wrong with it. To protect your engine from further damage, you will need to address a bad coolant temperature sensor promptly. While the engine will still work when it goes bad, it leads to a host of problems that can develop into more serious issues. It's the first line of defense against overheating in your engine. The coolant temperature sensor is a very important part of your car that monitors the engine's temperature. How to Deal with a Bad Coolant Temperature Sensor? A bad connection to the ECU could prevent the car's computer from receiving data from the sensor, resulting in temperature measurement problems. The sensor also fails as a result of bad or loose electrical connections. A coolant temperature sensor could either fail as a result of corrosion building up on the sensor, which would render it incapable of accurately detecting temperature. There are two main causes of a bad coolant temperature sensor. What Causes a Bad Coolant Temperature Sensor? A problem with the coolant temperature sensor could cause the engine to receive too much fuel, which will greatly impact the engine's fuel economy. 5) Poor Fuel EconomyĪs we mentioned before, the readings from the coolant temperature sensor are used to determine the amount of fuel the engine will consume. This results in incomplete combustion in the cylinders, which causes black smoke to come out of the exhaust. A problem with the sensor can result in excess fuel being sent to the engine. The coolant temperature sensor controls the amount of fuel being delivered to the engine. As a result, it triggers the check engine light. 3) Check Engine Light is OnĪ bad coolant temperature sensor is a serious problem that poses a risk to the engine. If the engine temperature seems to be colder or hotter than it normally would be, then there may be a problem with your temperature sensor. If the coolant temperature sensor is bad, the engine temperature gauge will not display an accurate reading. This causes a hard start condition or a no start condition in serious cases. When a faulty coolant temperature sensor causes a bad fuel-air ratio, the car won't be able to crank effectively. Here are some signs that your coolant temperature sensor has gone bad: 1) Hard Start Noticing one or more of these symptoms indicates that your car's coolant temperature sensor is failing. This will result in certain symptoms that can easily be observed. What Are the Symptoms of a Bad Coolant Temperature Sensor?Ī bad coolant temperature sensor will negatively impact the car's performance. When the sensor goes bad, the car might shut off the engine or reduce the amount of fuel delivered to it, making it harder for the car to start. The ECU then manages the heat level of the engine by adjusting the fan speed and fuel consumption rate. The coolant temperature sensor detects the temperature of the engine by measuring the heat in the coolant. The hot coolant is then pumped through the radiator where cool air removes the heat from the coolant. To understand how a bad coolant temperature sensor causes hard starting, we will first need to understand how a coolant temperature sensor operates.Ĭoolant runs through pipes in the engine and removes heat from the engine. How Does a Bad Coolant Temperature Sensor Cause Hard Starting?
