What Causes the Abnormal Noise When Accelerating in an Odyssey?
2 Answers
Odyssey may produce abnormal noise when accelerating due to excessive impurities, excessive carbon buildup in the throttle, or damage to the clutch release bearing. Excessive impurities: When the fuel pump motor is worn or contains impurities, abnormal noise will occur when accelerating. This issue requires replacing the fuel pump. Motor gear wear: Modern throttles are electronically controlled, with the valve opening and closing managed by a motor. When the motor gears are worn, insufficient engagement can cause abnormal noise. Clutch release bearing damage: Incomplete separation of the clutch disc can produce abnormal noise, requiring removal of the clutch to replace the release bearing.
From my years of experience driving the Odyssey, abnormal noises when accelerating usually involve several key components. The most likely culprit is a loose or worn drive belt, which produces a squeaking sound during acceleration, resembling fine friction noise. Damage to the CV joints on the driveshaft is also common—especially when accelerating during turns, it often creates a clicking sound, usually caused by a torn boot allowing dirt accumulation. I’ve also encountered cases of air intake system leaks, where faster airflow generates a whistling noise, like someone blowing a whistle. My suggestion is to start the engine, have someone gently press the accelerator while you open the hood and carefully listen for the source: if it’s near the front of the engine, it’s likely a belt issue; near the wheels points to drivetrain components. Don’t delay addressing this—last time I ignored it, a failed tensioner ended up costing a lot in parts. Regularly checking belt tension and CV joint condition can prevent major repairs, but for safety, it’s best to have a professional shop diagnose it.
