Land Rover Fuel Injection Throttle Body - Genuine Land Rover LR078546

Product Information

A Fuel Injection Throttle Body is a component in a vehicle's fuel injection system that controls the amount of air entering the engine. It consists of a throttle plate that opens and closes based on the driver's accelerator pedal input. The throttle body plays a crucial role in regulating engine power and efficiency by managing the air-fuel mixture that enters the combustion chamber.

• Poor Acceleration or Hesitation: A malfunctioning throttle body can lead to poor acceleration or hesitation during driving, particularly when the driver presses the accelerator pedal. This can result from a stuck or faulty throttle plate that doesn’t open or close properly
• Rough Idle or Stalling: If the throttle body is dirty or malfunctioning, it may cause the engine to idle roughly or stall, especially when coming to a stop or during low-speed driving. This is often due to incorrect air-fuel mixture or air supply issues
• Check Engine Light: A faulty throttle body may trigger the Check Engine light. Diagnostic trouble codes (DTCs) related to the throttle position sensor or airflow may be stored in the vehicle’s system, indicating issues with the throttle body.

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
