What Are the Effects of a Faulty Exhaust Sensor?
1 Answers
The sensor installed on the exhaust pipe of a car is called the oxygen sensor. Below are the effects a faulty sensor can have on the vehicle: 1. Increased fuel consumption: The vehicle consumes more fuel. If the upstream sensor is damaged, the vehicle will enter an open-loop control state, and the computer cannot detect the oxygen content in the exhaust, leading to excessive fuel injection. Fuel consumption may increase by 3 to 10 times. 2. Reduced power: The vehicle's acceleration performance declines. Excessive fuel injection cannot be fully burned, resulting in a noticeable drop in power. 3. Black smoke from the exhaust pipe: Incompletely burned fuel mixture is emitted into the air, causing thick black smoke.
