P0115 – Engine coolant temperature (ECT) sensor circuit malfunction Trouble Code Fault Location Probable Cause P0115 Engine coolant temperature – (ECT) senso Wiring, ECT sensor, ECM
How does an engine coolant sensor work on a car?
This way, the computer knows how hot the engine is running and if it’s getting close to overheating. The ECT sensor may also control the temperature gauge on your dash, though in some vehicles, that is done instead by the engine coolant sending unit, otherwise known as a temperature switch.
Where is the coolant temperature sensor located on a Mercedes Benz?
Replacing the coolant temperature sensor is a relatively easy job if you have a lot of patience. The sensor itself is located below the air pump and between the thermostat and coolant pump housing. The sensor is actually held in place by a small clip that sits in a channel created by both the thermostat on one side and coolant pump on the other.
How to change coolant in Mercedes Benz W203?
The cover is held on by five clips (red arrows) and will easily come off with hand pressure. Locate the tensioner and using the Torx driver turn it counter-clockwise 45 degrees. You can now slip the belt off the tensioner and install the new one.
What causes coolant to leak from under the motor?
If this occurs, the potential of overheating becomes greater. If your engine is overheating occasionally, the problem may be with the coolant temperature sensor. Coolant is leaking under the motor: it’s also common for the coolant temperature sensor to become loose and cause engine coolant to leak from under the motor.

The sensor is actually held in place by a small clip that sits in a channel created by both the thermostat on one side and coolant pump on the other.
Coolant sensors are fitted like a spark plug, so you need to unscrew it to remove it. Using a deep socket and ratchet, carefully loosen the sensor in an anticlockwise direction, without applying too much pressure. A squirt of release spray can help free up stuck sensors. Once the sensor is loose, unscrew by hand and remove it from the socket.
What does the air temp sensor on a Harley Davidson do?
If it see’s the engine getting to hot is cut the power back to prevent any damage. the also cause problem starting if they fail like it will start then stall the only to keep it running is to keep the throttle open 27381-06 Intake Air Temp. Sensor kit, w/screws That’s out of the 2007 Touring Model parts book.
Can a bad crankshaft sensor cause the engine to stall?
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
What happens if temperature sensor on car goes bad?
A faulty sensor can lead to a range of problems developing, including overheating and poor engine performance. That’s why it’s important to know how to spot the signs of a faulty or failing temperature sensor, before it can cause further problems which could prove more expensive to fix.

What are the symptoms of a bad coolant sensor?
Common symptoms of a bad engine coolant sensors are overheating, hard starting conditions, poor idle, check engine light ON and the electric fans do not work properly. The easiest way is to read the trouble code memory and check the value from the sensor, to make sure it’s a possible value.
What is the function of the coolant temperature sensor?
The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.
Where is the coolant temperature sensor located?
The engine coolant temperature sensor is usually located on the engine block or cylinder head . It is often installed on a plastic hose on the coolant’s inlet. Different brands and car manufacturers have different ways of placing the coolant temperature sensor depending on the car design.
What does a low coolant sensor do?
The sensor is designed specifically to detect low coolant, so if the level in the reservoir drops low, and the light does not come on, that may be an indication of a problem with the sensor or perhaps the wiring.
