How to Measure an Oxygen Sensor?

Measuring an oxygen sensor can be done using the following methods: 1. Multimeter Resistance Measurement Method: This method utilizes the resistance characteristics of the oxygen sensor to determine its resistance value in both warmed-up and non-warmed-up states, thereby assessing whether it is damaged. 2. Multimeter Voltage Measurement Method: Maintain the engine speed at around 2500 rpm for approximately 90 seconds, then use a multimeter to measure the voltage at the oxygen sensor's signal output terminal. 3. Oxygen Sensor Tester Inspection Method: By observing the flashing or extinguishing of the indicator light on the oxygen sensor tester, you can determine whether the sensor is functioning normally. The oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system. It plays a key role in controlling vehicle exhaust emissions, reducing environmental pollution caused by automobiles, and improving the fuel combustion quality of the car engine.

Do tires need to be replaced after 7 years?

Tires generally have a lifespan of 3-5 years. If tires have been used for more than 7 years, they have exceeded their service life, which can significantly compromise safety performance and must be replaced. Related information: 1. Considerations: Mileage is not the sole factor in determining whether tires need replacement; the age of the tires is also a critical factor. Tires are rubber products, and over time, the rubber will deteriorate. Even if the tread appears relatively intact, tires that have exceeded their recommended lifespan should be replaced because aged tires are highly prone to blowouts. 2. Additional information: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims, supporting the vehicle body, absorbing external shocks, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
