What are the symptoms of a faulty transmission position sensor?
2 Answers
Symptoms of a faulty transmission position sensor are as follows: Automatic gear disengagement: When the transmission sensor is damaged, the vehicle cannot determine its real-time gear position, which significantly affects the transmission's shifting logic. Additionally, gear disengagement can easily cause component wear and housing deformation, leading to serious consequences. Gear confusion: During driving, the vehicle should start in first gear, but due to sensor issues, the transmission may fail to determine the operating condition, potentially shifting into a higher gear. Reduced power: This occurs because the transmission cannot determine the correct gear position, and shifting confusion greatly affects the vehicle's acceleration performance. Severe shifting jerkiness: There are many causes of transmission jerkiness, and sensor failure is one of the more common ones. Transmission jerkiness significantly impacts the driving comfort of the vehicle.
When my car's sensor failed before, shifting gears became extremely rough—sometimes the car would creep forward after shifting into reverse, or suddenly get stuck and stop moving when in Drive mode. The engine light kept flashing like a warning signal, and when I checked the dashboard, the gear display was completely messed up—it showed R when it was actually in P, which scared me to death. If this happened during a long trip, with unstable power output and fuel consumption skyrocketing, it could even lead to a roadside breakdown. I feel like this kind of failure is a common car issue, so it’s best to get it fixed at a repair shop ASAP. Otherwise, it poses serious safety risks and wastes fuel money. Last year, my friend delayed fixing it, and it ended up damaging the engine, costing way more in repairs. Remember, don’t wait too long—small problems can turn into big troubles!
