What Impact Does a Faulty Nitrogen Oxide Sensor Have on a Vehicle?
1 Answers
Below are the impacts of a faulty nitrogen oxide sensor on a vehicle: 1. Impact on measuring diesel vehicle exhaust: The nitrogen oxide sensor is a key component for measuring whether diesel vehicle exhaust exceeds standards. Damage to it will directly cause multiple engine warning lights to illuminate, while also storing related fault records in the control unit. 2. Impact on the diesel control system: A damaged nitrogen oxide sensor will cause the diesel control system to operate in an open-loop state, unable to accurately feedback emission data. As a result, the engine control unit cannot precisely adjust emissions, leading to the vehicle's emissions exceeding standards. Prolonged operation in this state can shorten the lifespan of the exhaust emission treatment equipment. 3. Impact on diesel combustion control: A damaged nitrogen oxide sensor can cause disruptions in diesel combustion control, leading to symptoms such as weak acceleration, rough idling, and failure to start.
