How to Replace the Throttle Body in a Hyundai Sonataby Contributor
The Hyundai Sonata is a mid-sized sedan and is known for generous headroom, a big back seat and a huge trunk. A long list of standard and safety features and a terrific warranty program, shot the Sonata to the top of buyers' lists when it made its debut in 1989. The 2001 Sonata came as the result of four rounds of improvements, offering better engines and significant upgrades in ride quality. This information details about installation of a new throttle body in models produced between 2001 and 2006.
Put the ignition in the off position and allow the engine to cool completely before servicing the vehicle. Disconnect the negative battery cable.
Remove the engine cover and remove the throttle body electrical connector. Loosen and remove the bolts that hold the throttle body.
Lift out the throttle body and its gasket. Discard the gasket. Clean the mating surfaces of the throttle body thoroughly to remove any gasket material or other dirt and debris.
Install the throttle body with a new gasket. Set the bolts in place on the throttle body and finger tighten them.
Torque the bolts to 21 foot pounds. Reattach the throttle body electrical connector. Replace the engine cover.
Reconnect the negative battery cable to the terminal. Start the engine and allow it to run for several minutes until it is warm. Check for optimal engine operation.
- Place a clean shop cloth over the opening to the intake manifold when the throttle body is removed so that debris cannot fall into the engine.
- Refer to an auto repair manual for detailed photos of the engine components and procedures.
- Watch where the tools are laid while working on the vehicle. Never lay any tools or parts on the battery which may cause sudden electrical charges and result in the battery losing its charge.
