What does a coolant level module do?

The purpose of the coolant level module is to minimize galvanic corrosion by reducing the amount of electrical flow through the coolant level sensor. The ECM continuously runs diagnostics on this circuit when the key switch is in the ON position or when the engine is running.

How do you test a low coolant level sensor?

Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.

How does coolant level sensor work BMW?

The sensor is a reed switch activated by the magnet on the float stick. When the float stick gets low enough the magnet opens the reed switch turning on the low coolant light. Disconnecting the sensor’s plug will also turn on the low coolant light.

Does the coolant temp sensor control the fan?

As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on. Additionally, it may signal the need for a richer fuel mixture or open the exhaust gas recirculation.

Where is the coolant level sensor located?

The coolant level sensor is located on the radiator or at the bottom of the expansion tank, depending on the make and model of your vehicle. The coolant level sensor works with a float that contains a ring magnet. The ring magnet closes the reed switch inside when there is enough coolant in the radiator.

Can a faulty coolant level sensor cause overheating?

Engine Overheating

If the coolant temperature sensor malfunctions, it could cause your car engine to get overheated. While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal.

How do you test a 2 wire coolant level sensor?

The first two wire system you can measure if the circuit is open or closed using the resistance setting. When there is no fault (i.e. the coolant level is OK) it should be open. It closes on fault. You can take out the level switch and move the arm up and down to check its working.

Why is my coolant light on when its full?

The most common reason for the coolant light to become illuminated is simply that the coolant level is too low. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. You may need to book a coolant change.

Where is the low coolant sensor?

A typical configuration places the coolant sensor inside the intake manifold, but some manufacturers place the sensor inside the cylinder head. All sensors are situated so that one tip touches the engine coolant.

Why is my coolant low but no leaks?

When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a blown head gasket, a fractured cylinder head, Damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock.

Why is my coolant light blue?

A blue engine coolant temperature light only indicates one thing: that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that it is possible for your radiator to get too cold, thus resulting in your engine freezing up and not being able to start.

Why does my BMW say coolant level low?

When the cooling system reaches a low pressure, the car might perceive this as low coolant. In this case, the sensor will likely need to be replaced. Coolant leaks can occur due to a number of reasons, including a broken radiator seal or a compromised radiator.

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.

What sensor controls the engine 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.

Does temperature sensor turn on fan?

Does Temperature Sensor Turn On Fan? This sensor is designed to work on a fixed setting, which is the temperature at which the thermostat hands off. It’s the control system, the onboard temperature is the on-board system. If the CTS’ temperature goes up the control system switches on its cooling fan.

Can you drive with the coolant light on?

The coolant pressure warning light is an important one – your vehicle is telling you that your engine is overheating due to low coolant. If this light has turned on and you’re wondering if you can continue driving, the answer is you shouldn’t. An overheating engine can lead to engine damage which can be costly repair.

What is a coolant sensor?

A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.

Will engine coolant temperature sensor keep car from starting?

The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
