What Are the Effects of Faulty Car Sensors?

[Olga]

The effects of faulty car sensors are as follows: 1. Oxygen Sensor: When the oxygen sensor fails, the ECU cannot obtain this information, and an inappropriate air-fuel ratio will lead to reduced engine power and increased emissions; 2. Wheel Speed Sensor: It primarily collects the car's speed to determine if there are signs of skidding, usually installed on the hub of each wheel. Once the sensor is damaged, the ABS will fail; 3. Coolant Temperature Sensor: When the coolant temperature sensor fails, it often displays the temperature signal of a hot engine during a cold start. The ECU cannot receive the correct signal and can only supply the engine with a leaner mixture, making it difficult to start the engine when cold, accompanied by unstable idle operation and insufficient acceleration power; 4. Electronic Throttle Pedal Position Sensor: When the sensor fails, the ECU cannot detect the throttle position signal or obtain the correct position of the throttle pedal, resulting in weak engine acceleration or even the engine's inability to accelerate; 5. Intake Pressure Sensor: The intake pressure sensor senses a series of resistance and pressure changes with different engine speeds and loads, converting them into voltage signals for the ECU to adjust fuel injection volume and ignition timing angle.
