Where is the torque sensor of the engine located?

Under the steering wheel, locate the power steering motor on the steering column. The torque sensor for power steering is usually a small metal cover with four wires attached to the motor. Additional information about torque sensors is as follows: Classification: Torque sensors, also known as moment sensors, torsion sensors, or torque meters, are divided into two main categories: dynamic and static. Dynamic torque sensors can also be referred to as torque transducers, torque-speed sensors, non-contact torque sensors, or rotary torque sensors. Introduction: Torque sensors are used to detect torsional moments on various rotating or non-rotating mechanical components. They convert physical changes in torque into precise electrical signals. Torque sensors can be applied in manufacturing viscometers, electric (pneumatic, hydraulic) torque wrenches, and offer advantages such as high precision, fast frequency response, reliability, and long service life.
I usually drive regular family cars and have some experience with torque sensors. Actually, it's not directly on the engine block, but typically hidden near the flywheel or transmission. For example, in most gasoline cars, it's installed where the engine output shaft connects to the transmission or on the flywheel ring. If I were to check it myself, I'd first open the engine hood and look toward the transmission area. It looks like a small cylindrical component with multiple wires. What does this sensor do? It measures the output force of the engine to help the automatic transmission shift smoothly and prevent jerking. If it fails, you'll feel a lack of power or sluggish throttle response, and you should replace it at a repair shop immediately. During routine maintenance, don't forget to clean the surrounding dust to prevent buildup from affecting accuracy. In short, knowing its location can help you spot potential issues early.
I've been repairing cars for over a decade and frequently work with torque sensors. They're typically located at the flywheel on the engine's rear end or the transmission input, directly mounted on the drive shaft. For example, in automatic transmission vehicles, you can find it by removing the transmission cover – it's attached there to measure rotational speed and torque. Why is it important? It continuously monitors engine output and coordinates with the control system to ensure smooth acceleration and fuel efficiency. If the sensor fails, the dashboard warning light will illuminate, and the vehicle may experience jerking or stalling. I recommend regularly using a diagnostic tool to check signal values. The location varies slightly between vehicles – sedans usually have it under the chassis, while SUVs may position it higher. The repair isn't overly complicated but requires professional tools for proper positioning. Safety first – don't attempt disassembly without proper expertise.
