Where is the crankshaft position sensor of Nissan Qashqai?
2 Answers
The crankshaft position sensor of Nissan Qashqai is located near the engine flywheel. The principle of the crankshaft position sensor is to provide signals for ignition timing (ignition advance angle) and confirm the crankshaft position, which is used to detect the top dead center of the piston, crankshaft angle, and engine speed. Below is relevant information about the crankshaft position sensor: 1. Working principle: The crankshaft position sensor is usually installed at the front end of the crankshaft (near the pulley), the rear end of the crankshaft near the large flywheel, or the middle of the crankshaft. Early models also had it installed inside the distributor, making it one of the most important sensors in the control system. Its functions include: detecting engine speed, hence also known as the speed sensor; detecting the top dead center position of the piston, thus also called the top dead center sensor, including detecting the top dead center signals of each cylinder for ignition control and the top dead center signal of the first cylinder for sequential fuel injection control. 2. Three types: magnetoelectric induction type, Hall effect type, and photoelectric type.
The crankshaft position sensor of the Nissan Qashqai is generally installed at the lower part of the engine, near the flywheel, specifically in the rear right area of the engine. As someone who often works on my own car, I can see a small black box with a wiring harness above the exhaust pipe when I open the hood—that's the location of the sensor. When removing it, first disconnect the negative terminal of the battery to avoid short circuits, then use a wrench to loosen the fixing screws to remove it. Be careful not to touch other pipelines to prevent oil leaks. The sensor monitors the crankshaft speed and affects the ignition system. If it fails, the car may not start or have unstable idling, which can impact safe driving. Last time I encountered a similar issue, I replaced the sensor myself and solved the problem. Remember, its position is generally near the transmission box, and it may vary slightly for different model years of the Qashqai, but the location is roughly the same.
