How to troubleshoot the electronic power steering failure in Hongguang S?

[DelMicah]

Hongguang S electronic power steering troubleshooting methods are as follows: 1. Steering system: Check the steering gear, steering pump control valve, oil cup filter, steering oil, and clean the entire power steering system. 2. Check tires: Inspect tire pressure and replenish if low. 3. Connection parts: Examine all connection points of the oil pipes and tighten all connecting bolts. 4. Power steering gear: Replace oil pipes, power steering pump, or power steering gear. Additional information: Electric power steering system is a power steering system that directly relies on a motor to provide auxiliary torque. Compared to the traditional hydraulic power steering system (HPS), this system eliminates the hydraulic power steering system and directly provides steering assistance through an electric power machine.

As an experienced mechanic, I've encountered plenty of electronic power steering failures in the Hongguang S. The troubleshooting method is quite simple but requires attention to detail. Start with the battery - voltage shouldn't drop below 12 volts, just measure it with a multimeter since the power steering system relies entirely on electrical power. Fuses are common culprits; look for the power steering fuse in the engine compartment fuse box - they burn out easily, so pull it out and try replacing it. Loose or dirty sensor connections can also cause malfunctions, especially the torque sensor - just clean or tighten the connections. When symptoms like heavy steering or unusual noises appear, don't experiment randomly - reading OBD fault codes is crucial. Scanning for P-codes will help pinpoint ECU or motor issues accurately. If initial troubleshooting doesn't improve the situation, I recommend taking it directly to a professional shop. Don't try to save small money at the risk of creating bigger safety hazards. Always disconnect the negative battery terminal before working for safety.

I've been driving the Hongguang S for several years. Last time when the power steering failed, it was as heavy as pushing a rock, but I managed to troubleshoot it myself. First, check the fuse box—it's under the cover below the driver's seat. Look for the power steering fuse; replacing a fuse that costs just a few bucks can bring it back to life. If that doesn't work, check the battery voltage. Charge it overnight with a charger and try again—the power steering system is a big power consumer, so don't overlook this. Simply wiggle the sensor connector; the Hongguang S's connector near the steering column often gets loose, so just re-plug it. If the lights are working but the power steering isn't, it might be due to aging wiring—check if the ground wire is corroded. Don't disassemble complex components like the ECU yourself. Save money by going to a local shop for a code read—it only costs a few dozen bucks to get it fixed in one go. Combine the fun of DIY with practicality to avoid making things worse.

I'm fascinated by automotive electronics, and troubleshooting the power steering system in the Hongguang S is quite cool. The power steering system relies on torque sensors, the ECU, and the motor. If the sensor signals go haywire, power assist fails. Using an OBD scanner to read fault codes is efficient—for example, if it shows an abnormal sensor code, you may need to clean or replace the connector. Check that the battery connections are secure and the motor wiring is intact, as poor grounding is a common issue that can be checked with a multimeter for continuity. Regularly monitoring changes in steering feel can provide early warnings. For complex issues, visiting a specialized repair shop with professional tools saves time and ensures safety.
