The throttle shaft in an engine is held in the idle position primarily by the throttle return spring, which provides the necessary tension to keep it closed when the accelerator pedal is released. Additionally, the idle stop screw may be used to set and maintain a specific idle position by limiting how far the throttle plate can open. In some systems, the engine management system may also play a role in controlling the idle position electronically.

What holds the throttle shaft in the idle position on a Briggs engine?
On a Briggs & Stratton engine, the throttle shaft is held in the idle position primarily by a combination of a throttle return spring and the governor system. The throttle return spring provides tension to keep the throttle in the idle position when no other forces are acting on it. Additionally, the governor mechanism helps regulate engine speed by adjusting the throttle position based on load and speed, ensuring the engine maintains a stable idle when not under load.
Which governor component applies force to the throttle shaft in an effort to move it to the wide open throttle position?
governed idle spring
Where is idle speed sensor located on a 1990 Chevy Z71?
If you are looking for the throttle position sensor, it is located at one end of the throttle plate shaft, on the side of the throttle body, opposite side to where the throttle cable is attached.
Where can you find the throttle position sensor in a 1993 Oldsmobile cierra cutlass?
The Throttle Position Sensor (TPS Sensor) is located underneath the air intake< right below the Idle Control Valve. If your new, Find where your throttle cable hooks up & its right there. Its on the throttle body. When you follow the throttle cable, you will see it go to a lever that turns a shaft. The TPS is on the opposite end of the shaft.
On a Ford Escort where is the idle position sensor located?
You have an idle air control valve and you also have a throttle position sensor. They are both located and the throttle body.
Adjust idle speed on 1994 trans am?
the TPS (throttle position sensor) controls the idle.
What is a Tps throttle switch?
TPS (throttle position Sensor) is a variable potentiometer! Is is connected to the throttle shaft on the throttle body. The ECM/PCM (computer) uses the voltage from the TPS to determine fuel delivery based on the angle of the throttle shaft or valve (driver demand) A loose or broken TPS can cause an unstable idle or intermittent bursts of fuel from the fuel injectors, because the ECM/PCM is fooled into thinking the throttle is moving.
Ford escort 1991 when have scan and find the code 12 12 what means that code?
Code 12 displayed during self test, per Ford, takes you to test TP, for the throttle position sensor. It could be the failure of the throttle position sensor, idle speed or throttle stop adjustments, throttle shaft or linkage, and/or cruie control linkage.
What is a tp switch?
TPS (throttle position Sensor) is a variable potentiometer! Is is connected to the throttle shaft on the throttle body. The ECM/PCM (computer) uses the voltage from the TPS to determine fuel delivery based on the angle of the throttle shaft or valve (driver demand) A loose or broken TPS can cause an unstable idle or intermittent bursts of fuel from the fuel injectors, because the ECM/PCM is fooled into thinking the throttle is moving.
Is the throttle position sensor and the idle control valve the same thing?
No
What would cause the engine to rev to full throttle when throttle position is at idle on a polaris magnum 325?
It may be that the idle is set at max rpm on your carberator
What are the symptoms of throttle position sensor?
Symptoms of a failing throttle position sensor might include: Irregular idle Fast idle speed Engine is slow to return to idle speed Hesitation when depressing the accelerator General poor engine performance The ECM, engine control module, uses the throttle position sensor to know when the throttle has moved. If the ECM doesn't know accurately where the throttle is it won't know how much fuel to deliver when.
