There is no fixed replacement interval for the automotive oxygen sensor, but it is recommended to replace the oxygen sensor for vehicles that have traveled over 100,000 kilometers. More information about the automotive oxygen sensor is as follows: 1. The automotive oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system. It is a key component for controlling vehicle exhaust emissions, reducing environmental pollution, and improving the fuel combustion quality of the engine. Oxygen sensors are installed on the engine's exhaust pipe. 2. Once the oxygen sensor fails, the computer of the electronic fuel injection system will not be able to obtain information about the oxygen concentration in the exhaust pipe, thus failing to provide feedback control for the air-fuel ratio. This can lead to increased engine fuel consumption and exhaust pollution, as well as engine issues such as unstable idling, misfires, and surging.

How Often Should the Spark Plugs on a BMW X2 Be Replaced?

It is recommended to replace the spark plugs on a BMW X2 approximately every 30,000 kilometers. If spark plugs are not replaced for a long time, it can lead to various issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, which affects the normal operation of the vehicle. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced every 40,000 kilometers, standard nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers. Steps for Replacing Spark Plugs: Open the hood, remove the plastic engine cover, and disconnect the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and reattach the cover.

Why does the car rev up to 2000 RPM immediately after starting?

The issue of the car revving up to 2000 RPM immediately after starting is related to sensor signal problems. Below is relevant information about engine RPM: 1. Introduction: The engine RPM determines the number of power cycles per unit time or the effective power output of the engine, meaning the effective power varies with different RPM levels. Therefore, when specifying the effective power of an engine, the corresponding RPM must also be indicated. 2. Product Label: The effective power and corresponding RPM specified on the engine's product label are referred to as the rated power and rated RPM, respectively. The operating condition of the engine at rated power and RPM is called the rated condition. The rated power is not the maximum power the engine can produce; it is the maximum usable limit of effective power determined based on the engine's intended use.
