What Causes Car Sensor Malfunctions?

[VanLuke]

Car sensor malfunctions can be caused by the following reasons: 1. Carbon particle blockage: In this case, the oxygen sensor's signal voltage will be too high, causing the engine computer to issue a command to reduce fuel injection, resulting in an overly lean air-fuel mixture. 2. Dust and oil blockage: Here, the oxygen sensor's signal voltage will be too low, prompting the engine voltage to instruct the injectors to increase fuel injection, leading to an overly rich air-fuel mixture. Relevant information about car sensors is as follows: 1. Car sensors: These are input devices for the car's computer system, converting various operational conditions (such as speed, temperature of various mediums, engine operation conditions, etc.) into electrical signals for the computer, ensuring the engine operates in its optimal state. 2. Function: When diagnosing faults, besides checking the sensors, it's also necessary to inspect the wiring harness, connectors, and related circuits between the sensors and the electronic control unit.
