Why is my throttle body making a ticking noise?
The throttle bodies click loudly. It is most pronounced when the engine is cold at idle but is annoyingly loud even when warmed up and well off idle. My understanding is this is is caused by worn bushings that support the butterfly in the throttle body. If the throttle cable pulleys are touched, the clicking goes away.
What are the symptoms of a bad throttle body?
When the throttle body is not working properly, your car may stall, run rough, and/or lack power. Below is a detailed overview of the common symptoms of a bad throttle body.
Where are the throttle bodies located in a car?
Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold. Most cars use just one throttle body, though some engines (usually those with twin turbochargers) use two throttle bodies.
When to keep your fingers out of the throttle body?
KEEP YOUR FINGERS OUT OF THE THROTTLE BODY AT ALL TIMES!!! The car’s primary computer, which is often referred to as the powertrain control module (PCM), expects to see a certain amount of airflow through the throttle body. When that doesn’t happen, because the throttle body is dirty or faulty, the engine may stall.
How is the throttle plate in an ETC system?
An ETC system uses an electric motor to operate the throttle plate. On ETC systems, a redundant pair of throttle position (TP) sensors is mounted to monitor the position of the throttle plate, completing an important part of the feedback loop so the ECM/PCM can apply pulses to the plate motor to drive the plate to its desired target.
A bad throttle body may cause stalling in the vehicle, misfiring, electrical problems, high or poor idle, and improper throttle stop. Issues such as grime and dirt deposits or vacuum leaks can also cause problems to the throttle body. Below, you will find some further information about throttle body diagnostics.

Can a bad throttle body cause high RPM idle?
High RPM Idle The throttle body controls the engine’s idle to make sure it is always holding a steady RPM. If there is a problem with the throttle body, it may cause the be way too high. A not calibrated throttle body can also cause this.
Why does the Check Engine light come on when throttle body is bad?
As soon as the car’s onboard computer detects a problem with the throttle body signal, it will cause the check engine light to illuminate. The check engine light also comes on due to several other reasons, which is why we recommend to visit an auto specialist and have the car scanned for any trouble codes when it pops up on your dashboard.
