What are the symptoms of a faulty speed sensor in the Sagitar?
2 Answers
The symptoms of a faulty speed sensor in the Sagitar include unstable engine idle, momentary stalling or engine shutdown when starting or decelerating to a stop, reduced engine acceleration performance, inaccurate speed display on the dashboard, and illumination of the engine warning light. Symptoms of a faulty throttle position sensor: If the throttle position sensor is misaligned, it cannot ensure the correct ignition timing and air-fuel mixture ratio. Symptoms of a faulty coolant temperature sensor: If the coolant temperature sensor fails, the engine may exhibit unstable idle, misfires, stalling, or increased fuel consumption. A multimeter should be used to measure the sensor's resistance at various operating temperatures as specified by the manufacturer.
I've been driving a Sagitar for several years, and when the vehicle speed sensor fails, the driving experience becomes quite frustrating. The most obvious issue is the speedometer not moving or being inaccurate, often stuck at zero, forcing me to rely on my phone or intuition to check the speed. On highways, I'm always worried about speeding tickets, which makes me uneasy. The cruise control function stops working—pressing the buttons has no effect—making long-distance driving even more exhausting. The ABS warning light on the dashboard turns red, making me nervous every time. The automatic transmission shifts become jerky, with unstable power output, and the car shakes noticeably when accelerating. There are significant safety risks, so I recommend not delaying if you notice these symptoms—get the sensor wiring checked or the part replaced at a professional shop immediately. Ignoring it long-term could lead to other issues, such as the engine computer making incorrect judgments.
