What Are the Causes of Automotive Sensor Failures?

[SanAriana]

Automotive sensor failures can be attributed to the following reasons: 1. Carbon particle blockage: In this case, the oxygen sensor's signal voltage will be higher than normal, prompting the engine control unit 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 lower than normal, causing the engine control unit to increase fuel injection, leading to an overly rich air-fuel mixture. Relevant information about automotive sensors is as follows: 1. Automotive sensors: These are input devices for the vehicle's computer system, converting various operational conditions (such as speed, temperature of various mediums, engine operating conditions, etc.) into electrical signals for the computer, ensuring the engine operates in its optimal state. 2. Function: When diagnosing faults, in addition to checking the sensors themselves, it's also necessary to inspect the wiring harness, connectors, and related circuits between the sensors and the electronic control unit.
