A Modern car consists of many components and assemblies. And even the smallest malfunction of them can lead to very serious consequences. One of such small components is a sensor throttle position (TPS). What is this item and how to determine the fault? The answers to these and many other questions will learn in our today's article.

Feature element

Throttle – this is a constructive component of the intake system of gasoline engine. Its main purpose – adjusting the amount supplied to the engine air. In other words, this element controls the mixing of air and fuel in certain proportions. Set the TPS Vase and many other domestic cars between the intake manifold and air filter.what is a TPS

By design, the throttle position sensor – it is a kind of air valve. When the element is in the open state, the pressure in the intake system of the car is equal to atmospheric, and when closed, this value is reduced to that of a vacuum.

Position Sensor throttle includes a single turn of constant and variable resistors. Their resistance amounts to about 8 ohms. One of the extreme conclusions of this element of the controller is small reference voltage (in this case, the second terminal connected to the “ground”). Hence through a resistor to the controller is a signal about the actual throttle position at the moment. Often, this impulse voltages ranging from 0.7 to 4 Volts depending on the level of the position of the element.

Varieties

There are two types of TPS. What these elements are? It can be a detail with mechanical or electric drive. The first is often used on low-end cars. All its constituent elements combined in a separate block, which includes such details as:

  1. The Case.
  2. The Throttle.
  3. Sensor.
  4. The IAC (the IAC).how to check TPS

The throttle Body is included in the cooling system of the car. There are pipes that power the systems of the evaporative emission and crankcase ventilation.

The IAC maintains the frequency of rotation of the crankshaft of the internal combustion engine when the throttle is closed during startup and warmup of the engine or when operating the additional equipment. The IAC consists of a stepper motor and valve. These components regulate the flow of air that flows into the intake system to the bypass valve.

However, in the last few years, more automakers have their cars dampers with electric actuator. Such elements have their own electronic control system, which ensures optimal torque at all speeds and loads of the machine. This not only increase power and dynamics, but also reduces fuel consumption and emissions related.

Differences between electric damper

What distinguishes this item from their mechanical counterparts? The main differences are the lack of mechanical connection between the gas pedal and DZ, as well as in regulation XX by moving the flap.sensor throttle position price

But that's not all of its features. As between gas pedal and throttle is no tight coupling, the electronic system can itself affect the magnitude of the torque of the internal combustion engine even if the driver presses on the accelerator. All of these changes occur because of the actions of input sensors, control unit and actuators.

In addition to the TPS, in the electronic control system there is a sensor in the accelerator pedal position and the position switch of the brake and clutch. Thus, the engine control unit responds to all signals from sensors and converts these pulses into control actions on the module of the valve.

Design Features of the module

This element includes such mechanisms as:

  • The Case.
  • The Throttle.
  • The Motor.
  • A Reducer.
  • Position Sensor throttle.
  • Return spring mechanism.adjusting the TPS

Sometimes the car has set 2 of the TPS. It gives the car? In principle, any power it does not add, however, a malfunction of one sensor work can continue second. Thus, the installation of two of the TPS is performed to increase the reliability of the module. These elements can be both non-contact and sliding contact. Also in the design of the module has emergency damper position. It operates thanks to the return spring mechanism. If the module came to a fault, it is changing the whole Assembly.

TPS: fault

Like any other item, sensor throttle position tends to fail. In this case, it is necessary to know the basic symptoms of its failure. So, what is TPS sensor symptoms?TPS malfunction

In the first place is to pay attention to the work of the engine idling. If itmomentum “float”, this may indicate malfunction of the sensor. Also a symptom of its malfunction may be the stopping of the engine at sharp reset of gas pedal. Very noticeable there is a malfunction of the sensor when the acceleration of the car. In this case, can be failures at a set rate (the impression is that the engine is not receiving fuel). Sometimes when driving the car may not respond to the gas pedal. In addition, the engine rpm may hang at the level of 1.5-3 thousand and not sink even when switched off the transmission at idle. That is, the symptoms of this element are directly connected with the operation of the engine, and any incorrect operation may damage the sensor or valve. If you notice any such symptom, then you need to check the efficiency of the TPS. VAZ-2114 "Samara" and its successors are diagnosed almost equally. So the instructions outlined below can be used on all cars domestic (and even foreign) production.

How to check the TPS on your own?

To Make a diagnosis of the throttle position sensor is possible without the help of the hands of experts. All you need of tools is a multimeter. So, turn on the ignition and look at the instrument panel. If it does not light "Check Engine”, raise the hood and look for the sensor flap.TAS VAZ 2114

Now we take in hands a multimeter and check the “minus”. To do this, turn the ignition off and find the “ground” among the wires. It is not difficult to do. Then again, turn on the ignition and find the power lead. So we make sure that the sensor is receiving power.

What next?

After that check the opening of the twentieth. They are on the sensor connector at the top or bottom. Connected to pin one of the wires on the multimeter, and the second will move the damper. If everything is OK, then at the slightest movement the voltage level on the device will change to the value on the battery. If the arrow on the scale of the multimeter still in place, you should inspect the variable resistor inside the TPS. What that element is and how to diagnose? This resistor is part of a flap sensor that changes its resistance depending on the level of pedal position. And verified it in the following way. To start on the remaining wire attached to the multimeter, turn on the ignition, and then the valve is moved very slowly. Thus it is necessary to look carefully at the state of the pointer on the scale of the instrument. There should be no jumps. If they are, most likely, the engine is malfunctioning.

The Correct setting of the throttle of the car

TPS sensor symptoms

How is the self-adjustment of the TPS? This operation does not require special skills and knowledge, so it can handle even a novice car enthusiast. To adjust, disconnect the corrugated pipe that holds the air. This item has been thoroughly rinsed of any potent solvent. It can be alcohol or gasoline. For convenience it is recommended to clear gofrotruba piece of cloth. But not only are we treated gasoline. Further, such manipulations are made to the intake manifold and throttle itself. After you've washed the last item, carefully inspect the external condition.

Proper configuration of position sensor throttle

If the valve has no mechanical damages, proceed to the adjustment procedure. For this you need to loosen its mounting screws to raise and sharply to release. Here we need to hear the blow on the stops. Next, adjust the tension screws until until the ‘biting” detail. Then fix the screws nuts and bolts weaken the sensor. Then gently swing his body and set its position so that the voltage was changed only with the throttle opening. Then you can back the locking bolts and to start operation of the vehicle. As you can see, adjusting the throttle sensor and its position – this is not a difficult process, to cope with which almost every car owner. At the same time on all repairs is enough to spend no more than 10-15 minutes of free time.

Conclusion

So, we know what the throttle, the TPS and what elements it consists of. Finally it should be noted how much the new sensor the throttle position. The price of this item varies from 200 to 800 rubles. It is sold in stores, and automotive markets.
