Service life of Toyota Prievia 2.4 accelerator

The throttle has no specific service life, so it should be replaced every 40,000 kilometers. According to car home's inquiry, Toyota Prievia 2.4 throttle has no specific service life. When the throttle valve is used for a long time, it is easy to attach dirt to the joint between the inner wall of the throttle valve and the flap, which makes the opening angle of the flap smaller, and carbon deposition will affect the air intake and cause idling jitter. Therefore, Toyota Prievia needs to change the throttle every 40,000 kilometers. Toyota Previa is an MPV produced by Toyota from 1990. It is called Estima in Japanese market, Tarago in Australia and Bullet, Overlord and Super Overlord in Chinese mainland.
