The Leopard P0318 sensor is located next to the handbrake lever, and the center console needs to be removed to access it. This fault code indicates a malfunction in Circuit A of the rough road condition sensor signal. The rough road condition sensor signal is typically a square wave transmitted from the control module of the ABS (Anti-lock Braking System) / Traction Control System (TCS) to the Powertrain Control Module (PCM). More details are as follows: 1. The Electronic Control Module monitors changes in crankshaft rotation speed to detect cylinder misfires. However, wheel speed variations caused by rough road conditions can also affect crankshaft speed, thereby interfering with misfire detection. The ABS and TCS systems can determine if the vehicle is driving on rough roads based on signals from wheel speed sensors. If the system detects severe rough road conditions that significantly impact misfire detection, it will instruct the Electronic Control Module to disable misfire detection to prevent recording incorrect fault information. 2. When this fault code appears, it is necessary to inspect the rough road detection sensor circuit installed on the lower control arm for any open circuits or poor connections. A broken circuit can cause abnormal engine operation. Normal function can be restored after repairing the circuit. Timely maintenance and repairs ensure stable, comfortable, and safe driving.

I've been driving a Leopard off-road vehicle for years, and the P0318 sensor is quite easy to locate near the chassis. That little gadget is responsible for monitoring bumpy road conditions, usually positioned beneath the engine bay or alongside the front subframe. Last time I checked it myself, I found it resembling a small square box stuck behind the inner fender of the left front wheel, close to the frame rail, secured with two screws. This type of sensor is actually quite sensitive—when the vehicle hits a pothole, it signals the ECU to prevent misfiring and avoid engine damage. If your malfunction indicator light comes on, it's best not to hit the road immediately. First, crawl under the car to check if any wiring harnesses are torn; rain-induced rust could also cause poor contact. If you really can't find it, head to a repair shop and use a lift for inspection. If you frequently drive on rough terrain, remember to regularly clean the mud around the sensor.

Last time my friend had a P0318 error code on his Leopaard, we spent half a day troubleshooting and found the road condition sensor stuck in the middle of the chassis. Specifically, it's located a bit behind the front axle, near the transmission skid plate, about the size of a matchbox wrapped in a rubber sleeve with three wires connected. This sensor is actually quite important—it protects the engine control unit from throwing false error codes when encountering heavy bumps, but its low position makes it prone to mud and water splashes. I'd suggest first cleaning the connector. If the sensor itself is faulty, replacement isn't expensive, just around 100 yuan at auto parts markets. Don't forget to check the wiring route—it's very noticeable when tracing along the chassis, that bulging part in the middle of the wire harness is definitely it.

The Leopard P0318 is a vibration sensor commonly seen adhered to the chassis main beam during car repairs. Its specific location is approximately 30 centimeters behind the front wheels. By removing the plastic underbody cover, you can spot a black cubic module, usually installed with an arrow indicator facing forward. This sensor detects the intensity of road impacts and may interfere with the engine ignition timing when abnormal. If the malfunction indicator light comes on, don't continue driving forcefully. First, turn off the engine and check for any signs of foreign object impact. In winter, frozen conditions might cause the rubber pad to fail. If you can't locate the issue, it's advisable to read the fault codes for confirmation—sometimes, it's just suspension vibrations transmitting to the sensor and triggering a false alarm.
