20181203· The garage fitted a new coolant temp sensor and everything on the car returned to normal (for 1 day) Checked menu and again **** I then sent the car back and told them that I have read that the connector can sometimes be dodgy. The garage closed the pins and refitted. Worked fantastic for 3 days until mid drive. Checked menu again and **** This is now back in the garage with the only ...
20210514· The coolant temperature sensor helps keep the engine at its optimal operation temperature and prevents it from overheating. It is the one that measures the liquid coolant’s temperature. The collected data will then be sent to the car’s computer, which it will use to determine whether it will continue to operate or will adjust certain engine functions to keep the engine within its …
20200329· If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
The situation when the car radiator cooling fan keeps running constantly can be caused mostly by a failing coolant temperature sensor or its wiring, broken fan start relay, damage to the electrical wires, electronic engine control unit (ECU) problems. To understand how the cooling fan should work correctly, you need to know at what temperature ...
20210220· The engine coolant temp sensor is a sensor that is designed to keep track of the temperature of your coolant when you’re driving your car around. It’s often exposed to the flow of coolant in your car either in the engine block or in the engine cylinder head, though there are some times when it’s exposed in both areas. Either way, your coolant temp sensor’s job is to gauge the ...
20210615· The coolant runs through the engine to keep your car at operating temperature and prevent overheating. And the coolant can also prevent freezing during the winter because the coolant is created for this specific purpose. Many sensors are regulating the work of the engine and send the data to the ECU that is the main computer on the car. This computer then evaluates the signal and delivers ...
20210627· Can a car drive with a bad coolant sensor? Maybe, here is why. Two types of coolant sensors are common. First is a coolant temperature switch. Second, is a coolant temperature sensor. A switch is used to turn things on and off. Those things can be...
20120410· The coolant temperature sensor, abbreviated as CTS, in your car is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason. The Coolant Temperature Sensor''s Function. This device works on the principle of dependence of potential difference in temperature.
20180821· HOW TO TEST COOLANT TEMPERATURE SENSOR. Any CarIn this video we will demonstrate how to test coolant temperature sensor on any car. All you are going to need...
20141219· Starting issues. Coolant Temp Sensor unplugged = starts fine. Thread starter unitzero; Start date Nov 12, 2014; unitzero Registered User. Nov 12, 2014 1 I''ve been having issues with starting the engine (BRD 170 TDI) over the last few months, I had thought it was the battery at 1st and swapped that and all was well for a few weeks but the problem returned. Sometimes it takes about 3 …
20191011· If the car is warm and I turn it off, if I restart within a min or so it’ll fire up first turn of the key but if you wait 510 min, you have to crank it for 510 sec to get it to turn over. As soon as I get the coolant temp sensor replaced I will let you know.
20200307· The short answer is, no, a bad or faulty coolant temperature sensor will not cause your car to not start. While your car will start, it is not good to have a nonworking coolant temperature sensor for long. If left unattended, it will cause other serious damage to your car. What is a coolant temperature sensor?
Unplugging the engine coolant temperature sensor before starting the engine may result in a no start, especially likely on a cold morning. Although the PCM will see the sensor is unplugged and has a default fueling strategy for such an event. It is more of a one size fits all approach and so a cold start in colder temperatures may prevent the engine from starting.
If you have to pump the gas pedal in the morning to keep your car running, you may have a bad engine coolant temperature sensor. The computer in every fuelinjected car must know two things before it can figure out the correct coldstart air/fuel mixture: the engine coolant temperature and the outside air temperature.
That''s a tricky question! Here''s the thing. There''s a difference between an “engine coolant temperature sensor” and a “temperature sender unit”. A temperature sender unit is relevant to the temperature guage in the cluster and that''s it. It''s rele...
20151117· Since the efficient flow of engine oil is required to maintain proper lubrication, a failed sensor or one that is not able to relay data can trigger a fail safe mode in the ECU. If it sends a signal that the pressure is low, the computer may prevent the engine from starting.
The best place to start in comparing your vehicle’s normal engine coolant temperature to see if it’s correct is with your thermostat setting. If you call your local auto parts store, like one of our partners below, they will be able to tell you what temperature your engine’s thermostat is designed to start opening. This will likely be somewhere in the 160 to 190 degree range based on ...
20160812· The rear CTS is a four pin sensor. It''s essentially two sensors in one. It sends a signal to the display for the coolant temperature gauge as well as a signal to the ECM for monitoring the mapped cooling system and also for maintaining the proper fueling requirements. It can most certainly have an affect on starting the engine.
Can a bad coolant temp sensor cause hard start? If the sensor is reading too high of temperature when compared to the ambient air temperature sensor when first started then the computer would see it as a problem and turn on the check engine light to use a known good reading. No start will not be caused by the sensor.
20151117· There are many sensors used for coolant temperature, air flow, engine speed, and component position. A defective crank sensor which is internally faulty or has the wrong air gap can cause a no start.
20210615· 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 …
20180629· But a faulty engine coolant temperature (ECT) sensor can cause havoc on an engine or its related systems. These are the most common problems: 1. Your check engine light is on: If the engine’s computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light. 2. Your engine stalls: When the engine is first started, it will require more fuel ...
20200713· For instance, if the coolant temperature sensor indicated a high temperature, the car’s computer might trigger the engine’s fan to start or to turn off. Bad coolant temp sensor symptoms Similar to any car’s part, the coolant temp sensor can get …
Possible problems that can cause a car to overheat range from a cooling hose leak, faulty cooling fan, broken water pump, or bad temperature sensor. When an engine overheats, it is either because the coolant is not cooling the engine or there is no coolant at all. If it is not obvious why your car is overheating, we recommended having a certified auto mechanic diagnose the problem. Regular ...
