Do you know about variable valve timing solenoid? If not then today we will give you complete information about oil control valve VVT.

This sensor is called Oil Control Valve VVT ​​Solenoid Sensor because this sensor is operated by oil pressure and helps in functioning of VVT system.

VVT system mainly helps in changing the timing of opening and closing of the intake valve in the car engine, it does this through VVT installed in the camshaft.

Inside the VVT ​​system, this sensor advances and retires the timing by creating oil pressure, hence it has the function of oil control valve in VVT.

So today we will tell you about what is Oil Control Valve VVT ​​Solenoid Sensor, how it works, how to check it, its causes and symptoms.

what is variable valve timing solenoid sensor

variable-valve-timing-solenoid

The main function of the VVT ​​solenoid sensor is to make the VVT ​​system work by presure of oil, which advances and retires the timing of the camshaft, which can change the timing of opening and closing of the intake valve, so that the right amount of air and fuel goes into the engine.

VVT solenoid sensor is used for better mileage performance and engine life and you can see this sensor in all petrol cars.

This sensor is installed in the intake and exhaust camshaft on the outside of the head and this sensor is of 2 wires. There is a mesh on the front side of this sensor and some galleries are made in it through which the oil goes to the VVT.

This sensor works with main negative or positive current and camshaft sensor, crankshaft sensor and ecm are connected with this sensor.

When you start your car at low rpm, this sensor does not work, but when you run the car at 2 to 3 thousand rpm, the ecm sends a signal to the VVT ​​solenoid sensor to advance and retire the cam timing.

Which changes the time of opening and closing of the intake valve. The valve starts opening and closing according to the rpm of the engine and for this the VVT ​​solenoid sensor is very important.

function of variable valve timing solenoid sensor

Oil control valve VVT ​​solenoid sensor sends oil pressure to VVT through the gallery of camshaft to change the position of the camshaft and advances and retires the timing which changes the position of the valve.

And for this work, signal comes from ECM in VVT solenoid sensor which does timing advance and retire and signal comes to ECM through two sensors.

In the engine, a crank sensor is installed on the top of the crankshaft, which sends information about the position of the piston and engine speed to the ECM. Similarly, a cam sensor is installed on the camshaft, which sends information about the position of the cam to the ECM.

When we drive the car at high speed, the crank sensor sends a signal to the ECM and the cam sensor tells the ECM the speed of rotation of the camshaft.

At that time, with the help of these two sensors, the ECM detects whether the VVT ​​system is to be activated or not. If the ECM feels that the VVT ​​is to be activated, then the ECM sends current to the VVT ​​solenoid sensor based on the signals received from both the sensors.

And advances and retires the timing which changes the time of opening and closing of the valve and the engine gets the amount of air and fuel it needs, this is how this sensor works.

variable valve timing solenoid cause

There are many reasons for solenoid sensor failure, which you may see later, know about all those reasons.

(1) . Due to not getting service done

The biggest reason for the failure of the solenoid sensor is not getting the service done on time. When you do not get the service done, the engine oil gets spoiled and becomes thick and this sensor works with the engine oil. When the thick engine oil goes into this sensor. So it gets choked and stops working this is the main reason

(2) . Reasons for clogged filter of solenoid sensor

There is a very fine mesh inside the solenoid sensor which is finer than our hair and after filtering through it, the engine oil passes through the camshaft and goes to the VVT, but when this mesh gets choked, this sensor does not work, which is called VVT system. also does not work and problem occurs

(3) . Due to solenoid sensor being shot

This sensor gets shot, its front part is fine but the part where the wiring connector is inside it gets shot, the signal does not go to it and it does not work but it is very less shot.

(4) . Due to broken sensor wire

A major reason for the non-functioning of the VVT ​​solenoid sensor is wiring. If for some reason the wire of one of its 2 pins gets broken or for some reason the signal does not come to the solenoid sensor, then this sensor does not work.

(5) . Due to connector failure

If for some reason the connector of the solenoid sensor becomes loose or its pin gets damaged, then this sensor does not work. For this, check both its pins and check the connector.

(6) . camshaft sensor not working

A major reason for this sensor not working is the camshaft sensor because this sensor gives information about the position of the camshaft to the ecm and then the ecm sends the current to the solenoid sensor. If the cam sensor gets damaged then the solenoid sensor also does not work. Is

variable valve timing solenoid symptoms

After the solenoid sensor gets damaged or there is a problem in it, you will see some symptoms which are as follows

(1) . check engine light comes on

Whenever the solenoid sensor goes bad, the yellow check engine warning light turns on in the dashboard of your car, seeing which we scan the car.

(2) . code of p0016 and p0017 will appear

After scanning your car after solenoid sensor is bad or there is a problem with it, the code of p0016 and p0017 is generated which is for timing advance or retire, this is the main symptom.

(3) . engine oil will be bad

The biggest reason for solenoid sensor failure is bad engine oil and its symptom is also bad engine oil. If the solenoid sensor code comes then you need to check the engine oil and change the engine oil.

(4) . there will be problem of rough idling

As soon as the solenoid sensor gets damaged, the problem of rough idling arises in your car. As soon as you start the car, the engine starts shaking because the right amount of air and fuel does not get into the engine. Due to the solenoid sensor getting damaged.

(5) . Petrol consumption will increase

If the check engine warning light comes on in your car and along with it the code p0016 and p0017 is generated then the petrol consumption in your car increases because the air and fuel mixer in your car gets damaged due to the solenoid sensor getting damaged. Reasons why VVT does not work

how to check vvt solenoid sensor

You can test VVT solenoid sensor by 2 methods, battery and multimeter, we will tell you about both the methods which are as follows.

(1) . How to check through battery

To check the VVT ​​solenoid sensor on the battery, you will need 2 wires. You have to take the VVT ​​solenoid sensor and connect both the wires to both the pins of the sensor.

After that, one of those two wires has to be connected to the negative terminal of the battery and the other wire has to be connected to the positive terminal of the battery. As soon as you connect the wire, the VVT ​​solenoid sensor will make a sound. If it makes a sound, then the sensor is fine. If it doesn’t make sound then there is a problem with the sensor.

(2) . How to check with multimeter

You can also easily check the VVT ​​solenoid sensor with a multimeter. You have to take a multimeter and set it to 7 to 14 ohms.

After that you have to connect both the wires of the multimeter to both the pins of the solenoid sensor and check the points. If points appear then the sensor is fine, if not then the sensor is bad.

In this way you can easily check whether the solenoid sensor is bad or fine.

variable valve timing sensor location

You will find the VVT ​​solenoid sensor installed in the head of all cars. You can find this sensor installed in the bold number 10 near the timing cover in the camshaft part.

This VVT solenoid sensor is installed at two places in the car engine, one sensor is for the intake camshaft and the other sensor is for the exhaust camshaft.

And VVT solenoid sensor one is installed in the head from behind towards the exhaust side which reaches the camshaft and the other one is installed towards the timing cover towards the intake manifold.

how to clean vvt solenoid sensor

Whenever you face problems related to VVT solenoid sensor, you should clean the VVT ​​solenoid sensor before replacing the sensor.

You can clean this sensor in two ways, first with petrol, wash it with petrol and then clean it or you can use sensor cleaner.
