Where is the crankshaft sensor located on the Wuling Hongguang?
4 Answers
The crankshaft sensor on the Wuling Hongguang is located near the crankshaft pulley. The function of the crankshaft position sensor is to determine the position of the crankshaft, specifically its rotation angle. It typically works in conjunction with the camshaft position sensor to determine the basic ignition timing. Below is an introduction to the crankshaft sensor: 1. Magnetic Induction Type: The magnetic induction speed sensor and crankshaft position sensor are installed in the distributor in upper and lower layers. The sensor consists of a permanent magnet induction detection coil and a rotor (timing rotor and speed rotor), which rotates along with the distributor shaft. 2. Hall Effect Type: The Hall effect speed sensor and crankshaft position sensor utilize the Hall effect as a signal generator. The Hall signal generator is installed inside the distributor, coaxial with the distributor rotor, and consists of an encapsulated Hall chip and a permanent magnet fixed on the distributor plate. 3. Photoelectric Type: The photoelectric crankshaft position sensor is generally installed in the distributor and consists of a signal generator and a signal disc with light holes. The signal disc rotates with the distributor shaft. The outer ring of the signal disc has 360 light-slit gaps, generating a signal for every 1° of crankshaft rotation. Slightly inward, there are six evenly spaced light holes at 60° intervals, producing a signal for every 120° of crankshaft rotation. One of these light holes is wider, used to generate the signal relative to the top dead center of cylinder 1.
I previously replaced this sensor on my Wuling Hongguang vehicle. It's usually installed near the flywheel housing at the rear of the engine, in a somewhat concealed location that requires removing the underbody protection panel to access. The sensor plays a crucial role in monitoring crankshaft speed. If it's improperly positioned or dirty, the car may fail to start or experience severe jerking during acceleration. I've personally encountered this issue - while driving, the car started jerking intermittently, and upon inspection, I found the sensor connector had come loose. It took me half a day to properly tighten it. So, I recommend regularly cleaning the area around the sensor to prevent dust accumulation, which can reduce the risk of malfunctions and maintain smooth engine operation. Additionally, if you're having trouble locating it yourself, it's best to visit an auto repair shop where they have all the necessary tools to handle it quickly.
After driving the Wuling Hongguang for so many years, I had a sensor issue last time where the car would suddenly speed up and slow down, which scared me into checking its location. It's on the side of the engine, near the transmission area. To be more specific, squat down and look at the middle part of the chassis—there's a small black box connected with wires. Installation isn't difficult, but the position is awkward; you'll need a wrench to tighten a few screws. A faulty sensor can cause significant issues like increased fuel consumption and stalling, which I've experienced. After replacing it, everything ran smoothly again. I recommend checking if the warning light is on—if it is, this is likely the problem. Related topic: The engine compartment is tight, so take your time during inspection. Slowly refer to the manual or look for diagram videos online as a reference.
The crankshaft sensor of the Wuling Hongguang is usually fixed at the lower rear end of the crankcase, which can be spotted by peering into the engine bay. Its function is to read crankshaft data and maintain engine synchronization. A worn or malfunctioning sensor can cause difficulty in starting the car—I once had to call a tow truck for this issue. The search method is straightforward: lift the hood and trace the wiring to locate the rear connector. If the position is offset, professional adjustment may be required.
