Nissan Navara Throttle Body Cleaning Malaysia — YD25
Diesel engines still have a throttle body (intake air control butterfly valve) that can accumulate carbon deposits, especially on the EGR-equipped YD25. Carbon from EGR recirculation coats the throttle bore and butterfly valve. Symptoms: rough idle, hesitation, P2135 or idle control codes. Clean with dedicated throttle body cleaner every 40,000–60,000 km alongside EGR service.
