What is the fault when the EPS light is on in the Changan Honor?
4 Answers
When the EPS light is on in the Changan Honor, it indicates a fault in the power steering system, and the steering wheel will become heavier. The power steering systems in automobiles include: electric power steering system, electro-hydraulic power steering system, and mechanical hydraulic power steering system. The electric power steering system does not have hydraulic mechanisms; this system relies on an electric motor to provide steering assistance. The electro-hydraulic power steering system is actually developed based on the mechanical hydraulic power steering system. Both of these power steering systems have hydraulic mechanisms and require the use of power steering fluid. The electro-hydraulic power steering system simply adds some electronic systems to the mechanical hydraulic power steering system.
As a seasoned driver who has operated various vehicle models, I once encountered the EPS warning light illuminating in my Changan Ono, which really worried me at the time. Simply put, this usually indicates an issue with the electric power steering system—it could stem from minor faults in the steering motor, sensor detection failure, or insufficient battery power. If the battery is weak or voltage fluctuates, the system may trigger an alert; sensors on the steering column might send false signals if jammed or contaminated; worse, a faulty control module can completely cut off power assistance, making the steering wheel dangerously heavy. In such cases, I typically recommend first trying to reset the light by restarting the engine, or checking the battery and fuse box for any blown fuses. Regular maintenance should emphasize lubrication and cleanliness of the steering system to prevent surprises. It’s best not to tough it out—promptly visit a trusted repair shop to scan for trouble codes with diagnostic tools. Changan’s system is quite sophisticated; early professional intervention saves hassle if DIY isn’t feasible.
When repairing cars, I often encounter the issue of the EPS light being on. For vehicles like the Changan Honor, it's mostly due to internal bugs in the steering control unit or loose wiring connections. Specifically, once the torque sensor under the steering wheel wears out or gets dusty, it may falsely report a fault; if the power assist motor burns out, the light will stay on due to interrupted current; also, the fuse in the small box in the engine compartment is prone to aging and blowing—replacing it with a new one might solve the problem; if the battery negative terminal isn't tightened or the alternator isn't charging sufficiently, low voltage can also trigger the protection mechanism. To diagnose, use a multimeter to measure resistance and rule out simple issues first, then check for any damage or short circuits in the chassis wiring harness. It's recommended that owners avoid driving through water and making sharp turns to prolong lifespan, and not delay inspection once the light comes on.
As an owner of a Chana Ono, the first time I saw the EPS light come on, I thought the steering had failed. Actually, it's the system indicating a power steering issue, possibly due to dirty sensors or a weak battery. A simple fix is to try turning the car off and restarting it to let it self-check. If that doesn't work, you'll need to check the fault codes in the manual. When driving, be cautious not to be too reckless in rainy or muddy conditions, as the steering system can easily get dirty. If the light stays on, it's time to seek professional repair.
