The throttle valve (throttle plate) opens and closes to control how much air enters the engine, directly controlling engine power in response to the accelerator pedal.
For a throttle body, compare bore, mountings, connector and full part number. Resemblance to another unit for the same engine does not confirm its specification. Establish which accessories are supplied and whether adaptation is required. Cleaning the existing component and fitting a replacement are separate decisions that should follow diagnosis.
If you notice any of the following, the part likely needs replacement:
Rough or unstable idle
Hesitation or delayed response when accelerating
Check Engine light with a throttle-related fault code
Installation information
Bolts to the intake manifold with a gasket — a throttle relearn procedure is often required after installation on electronically controlled systems.
Frequently asked questions
Carbon deposits from crankcase gases and fuel residue collect on the valve and its bore, restricting airflow and preventing the valve from closing to its exact calibrated position, causing a rough idle.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
