Product & Technical
Are your new throttle bodies the same design as O.E.?
The new electronic throttle body is engineered and manufactured to match the O.E. design.
Is it OK to bypass the coolant hoses?
No, bypassing the coolant hoses is not recommended. There are cases where we sell units without coolant pipes, because we are following O.E. supersessions where the pipes have been removed. Instructions are provided for rerouting coolant hoses.
Do all throttle bodies have an ice-breaker mode for extreme cold starts?
Not all throttle bodies have this feature, where the throttle valve is reversed from its normal movement by the control module, which breaks up any ice formation between the throttle bore and valve. This feature is based on application.
What else does the throttle body control other than idle air bypass and acceleration throughout driving range?
The throttle body is also part of the cruise control, traction control, stability control, and pre-crash systems, as well as other systems that require engine torque management.
Will I have to modify anything on the vehicle to install your new throttle body?
When installing the new electronic throttle body, there is no need to modify the vehicle for installation.
What’s an electronic throttle body?
The electronic throttle body is a powertrain component that has a plate, motor, and integrated position sensors which are utilized to regulate the amount of air entering the engine by opening the throttle valve to a desired angle via commands from the vehicle’s powertrain control module or throttle actuator control module.
What happens when an electronic throttle body fails?
When an electronic throttle body fails, the controlling module will illuminate the MIL/SES/CEL. The module will then activate a fail-safe mode operation and gradually reduce the engine’s speed back to an idle RPM.
Is there anything that has to be done after installing the replacement throttle body?
A relearn calibration procedure is necessary after installation of replacement throttle body.
Can I purchase a throttle body with a bigger bore to increase horsepower and improve my throttle response?
Swapping your throttle body for one with a bigger bore is not recommended. The throttle bodies we sell are specific to the application.
Do you sell throttle body spacers?
We do not sell throttle body spacers, nor do we recommend the use of a spacer.
Is it OK to bypass the coolant hoses?
No, bypassing the coolant hoses is not recommended. There are cases where we sell units without coolant pipes, because we are following O.E. supersessions where the pipes have been removed. Instructions are provided for rerouting coolant hoses.
The O.E. throttle body has coolant hoses attached. What’s the purpose?
The purpose of the attached coolant hoses is to keep the throttle body warm by the transfer of heat from the coolant to the housing, preventing moisture from freezing between the throttle body bore and throttle valve during extreme cold temperatures.
What causes the electronic throttle body to fail?
The most common failure in an electronic throttle body is the integrated throttle position sensor. The ETB is equipped with high and low voltage reference throttle position sensor for redundancy. Either one of these sensors could fail, or possibly both.
