The throttle body on a Toyota Camry should be cleaned every 60,000 to 80,000 km under typical UAE driving conditions to prevent sluggish acceleration and maintain fuel efficiency. Primarily caused by dust and combustion byproducts, deposits can build up faster here due to the high ambient dust and frequent stop-and-go traffic on routes like Sheikh Zayed Road. A clean throttle body ensures the engine receives the precise air-fuel mixture based on signals from sensors like the MAF. For a 2020-2023 Camry with a 2.5L engine, allowing deposits to accumulate can reduce fuel economy by approximately 0.5-0.7 km/l, as noted in common workshop findings for GCC-spec vehicles. The total cost for professional cleaning at a reputable garage typically ranges between 120 to 180 AED, which is minor compared to the long-term impact on performance and fuel costs. Considering the annual depreciation of a mainstream sedan like the Camry in the UAE market, such preventive maintenance, highlighted in RTA Dubai's general vehicle inspection reports for common faults and MOI UAE's driving maintenance guidelines, helps preserve the vehicle's drivability and operational economy in harsh summer temperatures. This translates to a lower overall cost per kilometer over the vehicle's lifetime in the Emirates.
