Technical Specifications

Vehicle Fitment

Engine details (verify with VIN):

• 3.0L V6 Diesel 24V DOHC TC (306DT / TDV6 / SDV6)

Signs of Failure

• Rough idle or stalling – throttle plate sticking or actuator motor failure

• Reduced engine performance – hesitation or lack of power during acceleration

• Check engine light – throttle position sensor or airflow-related DTCs

• Limp mode – ECU may force limited engine operation to protect the drivetrain

💡 Throttle body failure can cause drivability issues and trigger fault codes. Proper diagnosis is recommended before replacement.

Critical – Verify Your VIN Before Ordering

Throttle bodies are VIN‑, engine‑, and model‑year‑specific. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.
