What is the normal idle speed for Nissan Teana?
2 Answers
The idle speed of the Teana is generally maintained between 750 rpm and 900 rpm under normal conditions. Idle speeds vary among different models: Different models have different idle speeds due to variations in engines. Typically, the idle speed ranges between 500 and 850 rpm. During a cold start, the idle speed can momentarily reach between 1500 and 2000 rpm. Once the engine coolant temperature returns to 90 degrees, the idle speed stabilizes within the specified range. About car idle speed: Car idle speed is not a type of speed but rather a working condition. When the engine runs without load, it is referred to as idling. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle opening, among other methods. Generally, the optimal idle speed is the lowest rpm at which the engine does not vibrate.
I've been driving the Teana for almost five years now, and this car has exceptionally stable idling. Under normal conditions, the tachometer needle basically stays fixed at the 700 RPM mark. During winter starts, the RPM might be slightly higher, initially surging to around 1000 RPM, but it gradually drops back to 700 after about half a minute as the engine warms up. If the air conditioning compressor is running, the RPM might increase by another 50 RPM or so, but these fluctuations are all within the normal range. During routine maintenance, I always specifically ask the mechanic to check the throttle body. Excessive carbon buildup can cause unstable idling, making the needle dance up and down erratically—that's when a cleaning is necessary. In short, remember that 700 RPM is the golden spot, and as long as the fluctuation stays within 50 RPM, it's considered a healthy condition.
