We realize that a position sensor does not work well when the engine experiences a lack of power when accelerating, idling is slow or hard.
How to diagnose a failing or faulty throttle position sensor?
The throttle position sensor (TPS) is part of your vehicle’s fuel supply management system and helps ensure that the right mixture of air and fuel reaches the engine.
{{{ad-code}}}
The throttle position sensor (TPS) provides the most direct signal to the fuel injection system in terms of the power requirements of the engine. The position sensor (TPS) signal is measured continuously and is compared several times per second with other data, such as air temperature, engine speed, air mass flow and how fast the throttle position changes.
The data collected determines exactly the amount of fuel that is injected into the engine at any given time. If the throttle position sensor and other sensor parameters work properly, the car accelerates smoothly, runs smoothly at cruising speed or decelerates smoothly and efficiently, as you expect, while maintaining optimal fuel economy.

The throttle position sensor (TPS) can fail in several ways, all resulting in, at best, unnecessary fuel economy and, at worst, a performance limitation that could create a safety hazard for you and other vehicles in traffic.
It can also cause problems with changing gears or setting the base spark ignition time generated by spark plugs. This sensor may malfunction gradually or will display all of the listed items simultaneously.
In most cases, the Check-Engine lights up if a throttle failure (TPS) is detected. Also, most manufacturers provide an operating system in case of malfunctions, equipped with a service coupling to connect to the LPG system.
Once the position sensor (TPS) starts to malfunction, you will need to replace it immediately. Replacing the position sensor (TPS) will include deleting the relevant error codes and may require reprogramming the new position sensor module (TPS) software to synchronize with other engine applications.
A qualified mechanic is able to perform all the necessary maneuvers, and can provide you with a qualitative diagnosis, and then perform the correct installation of the spare part.

Signs of Acceleration Position Sensor (TPS) Failure
1. The car does not accelerate, has no power when accelerating or accelerating on its own.
It can feel as if the car simply does not accelerate as it should or while increasing the speed does not manifest as it should. We can accelerate, but the engine has no power.
On the other hand, the car may suddenly accelerate while driving, even if you have not pressed the accelerator pedal. If these symptoms occur, there is a high probability that you have a problem with the throttle position sensor.

2. The engine will not run normally, will move too slowly, will not run at all.
If you have started to experience engine failures, very slow idle operation or idling when the vehicle is stopped, it may also be a warning sign of a faulty position sensor (TPS).
If idling is disabled, it means that the computer cannot identify whether the throttle is fully closed. Also, the position sensor (TPS) can send an improper input pulse as a result of the motor being suspended at any time.

3. The car accelerates, but will not exceed a relatively low speed or the gear change will be problematic in the higher gear.
This is another mode of failure of the position sensor (TPS), which indicates that there is a false limitation of the required speed. Your car may accelerate, but not exceed a speed of 30-50 km / h. This malfunction indicator often goes hand in hand with loss of engine power.
4. Check-Engine indicator light, accompanied by any of the causes listed above.
The check-engine may light up if you have problems with the position sensor (TPS). This is not always the main cause, so do not wait for the engine check indicator to light up before any of the above symptoms are checked. Check your vehicle’s error codes to identify the source of the problem.
The throttle position sensor is the key to obtaining the desired power and fuel efficiency from the vehicle in any driving situation. As the above indicators show, if this part fails, your traffic safety is seriously affected and the investigation of a qualified mechanic is a necessity.
