What is the solution for Honda Fit VTC abnormal noise?
2 Answers
Honda's Earth Dreams engines across the entire lineup experience oil dilution issues. Below is relevant information: 1. Starting: Whether manual or CVT, allow the ECU to complete self-check for at least 6 seconds before starting. My starting procedure is to turn the key to position II, shift to neutral, depress the clutch for manual transmission models, fasten seatbelt, wait briefly, then ignite. 2. Maintenance: Actually, VTC abnormal noise doesn't indicate VTC malfunction. Since VTC operation is triggered by oil pressure, engine oil is the root cause. Therefore, Fit's maintenance requires special planning. Many don't know how to choose engine oil - it's actually simple: any brand is acceptable as long as it's genuine. For the Fit, oil brand isn't crucial; what matters is planning maintenance intervals based on usage intensity, which then determines the oil selection.
I recently just fixed the VTC rattling issue with my Fit. That clicking sound during startup was particularly annoying. Actually, this is a common problem with the Fit, usually caused by issues with the oil pressure accumulator inside the VTC actuator. The most straightforward solution is to replace it with an improved version of the actuator assembly, as the new part has optimized internal structure. I replaced it myself—those with good DIY skills can give it a try, but be extra careful with the timing chain alignment, as getting it wrong can damage the engine. I recommend using OEM parts, as aftermarket ones don’t guarantee the same quality. Also, while you’re at it, it’s a good idea to check the timing chain tensioner, as these two failure points often go hand in hand.
