This category only includes cookies that ensures basic functionalities and security features of the website. 1 Answer Need to replace TPS on 2004 Jeep Grand Cherokee 6cyl. Earlier, most of these sensors were potentiometers, which provided variable current output, according to the position of throttle. Sensor troubleshooting is best handled by a professional, as it’s delicate work that requires a knowledge of the throttle mechanism, as well as functioning of ECU. It is the valve that regulates air flow in a car. More advanced forms of the sensor are also used. The first signal line is VTA1 and the second signal line is VTA2. The sensor is made of plastic and is usually secured with four screws and bolts. If you determine the throttle position sensor has failed on your Mercedes-Benz you will need to address this problem right away. This helps your ECU control the fuel and air mixture. Modern day sensors are non contact type. It is generally attached to the throttle body, as pictured above. Which is then fed to the engine control unit (ECU). The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine. We'll assume you're ok with this, but you can opt-out if you wish. Throttle Position Sensor. The function of the throttle position sensor (TPS) is; to supply information to the (ECU) about the position of the engines throttle. Fig. The engine Coolant Temperature Sensor is located on the back of the right cylinder head. The accelerator position sensor (TP) is located at the back of the suction manifold. The magnet may be of diametrical type, ring type, rectangular or segment type. The throttle position sensor (“TPS”) is a component of your car’s throttle body system. The throttle position sensor in the 2005 Sorento is responsible for reading the positioning of the valve inside the throttle body and transmitting its reading to the electronic control unit via a change in output voltage. It bolts over the throttle plate shaft and has three wires connected with a snap-in plug.

Just like one remembers landmarks to find a place, the location of a particular car part can be identified with respect to where it is positioned, in relation to some of the main car parts, that are easy to identify. Non contact type TPS work on the principle of Hall effect or inductive sensors, or magnetoresistive technologies, wherein generally the magnet or inductive loop is the dynamic part which is mounted on the butterfly valve throttle spindle/shaft gear and the sensor & signal processing circuit board is mounted within the ETC gear box cover and is stationary. Throttle Position Sensor Description & Related Information. The throttle position (TP) sensor is located on the throttle body. From the knowledge of the sensor’s function, you must have already guessed where the sensor location is. TP sensors are normally mounted on the throttle body with the throttle plate shaft running into the sensor. Standard® throttle position sensors match the OE and send a signal to the computer to show the throttle angle and speed of movement data. If you look under the hood, where the throttle cable is attached to the drivers side of the throttle body, it should be on just the opposite side of the throttle body. Just opposite the throttle lever, on the opposite side of the throttle body, the throttle position sensor is located. Some engine control units (ECUs) also control the throttle position electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control.[1]. The throttle position sensor reads the position of the gas pedal in your Engine Control Unit. Unplug the throttle sensor by lifting up the plug clip and pulling … Your options are to replace it with a new throttle position sensor.
