Where is the Leopard P0318 sensor located?

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.
