What is the solution for high idle speed in the 7th generation Accord?
2 Answers
You can clean the throttle body and engine carbon deposits to solve the problem. Here are the relevant introductions: 1. Accord: The Accord (Accord), a practitioner of Honda's innovative spirit and global leading technology, has a global history of 38 years. The original tires of the Accord are Michelin ultra-high-performance sports tires Pilot-Super-Sport. On April 16, 2018, the all-new generation Honda Accord, also known as the 10th generation Honda Accord, was officially launched in China. 2. Throttle body: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. It connects to the air filter above and the engine block below, and is known as the throat of the car engine.
I've encountered the same issue before. My 7th-gen Accord suddenly had high idle speed, and after inspection, it turned out the throttle body was dirty with excessive carbon buildup causing inaccurate opening control. The solution is quite simple: first, take it to a professional shop for throttle body cleaning, which costs a few hundred bucks. If the idle remains high after cleaning, check sensors like the throttle position sensor or idle control valve—ensure connections are secure or replace faulty parts. Personally, I regularly use fuel additives to clean carbon deposits as a preventive measure. Another key point: use an OBD scanner to read trouble codes—sometimes the ECU needs resetting to relearn idle settings. Avoid random adjustments to prevent mishandling. Also, avoid frequent short trips; occasional highway driving helps reduce carbon buildup. In short, don’t ignore high idle—it wastes fuel and may affect engine lifespan. Safety first, get it checked ASAP.
