How to Remove Torque Limitation on China VI Vehicles?
3 Answers
Torque limitation cannot be temporarily removed unless the fault causing the limitation is resolved. When encountering such a situation, car owners should drive to the nearest repair shop for inspection and maintenance. The vehicle's onboard computer is generally quite intelligent. If a certain fault could potentially damage the engine, the computer will limit the engine's power output to protect it.
I previously encountered a torque limitation issue with my China VI compliant vehicle, which is typically a protective response triggered by faults in the emission system, such as a clogged DPF or abnormal oxygen sensor signals. The most common resolution method involves using an OBD diagnostic tool to connect to the vehicle's computer interface and scan for trouble codes to identify the root cause. For soft faults, inputting specific codes can temporarily clear the torque limitation, but this only addresses the symptom superficially. Hard faults require actual repairs like DPF cleaning or component replacement. I don't recommend reckless attempts—I once tried a DIY torque limitation removal that didn't fully resolve the issue, leading to worsened engine misfires and a subsequent repair bill exceeding a thousand yuan. The key point is that torque limitation exists to protect both the environment and our safety. Bypassing it may mask underlying problems, potentially increasing pollution, damaging components, or causing inspection failures. It's best to regularly inspect the fuel system and particulate filter to maintain system health and minimize triggers. Safe driving far outweighs chasing temporary performance gains.
When my China VI-compliant car went into torque reduction mode last time, I immediately became alert, as this is the system's automatic way of preventing major failures by reducing torque. Simply removing the restriction isn't an option—it could mask potential hazards like excessive emissions or engine overheating risks. A friend told me his car suddenly limited torque on the highway; he pulled over and found a dirty sensor was the culprit, which was cleaned at a repair shop to restore normal operation. Arbitrary actions like disconnecting the battery or manual resets might backfire, potentially damaging the control module and creating more trouble. The torque reduction mechanism is meticulously designed with strict monitoring under China VI standards to protect both air quality and driving safety. Make it a habit to check your exhaust system monthly using simple scan tools for diagnostics—don't cut corners seeking quick fixes to avoid future problems. Safety should always come first.
