日产英菲尼迪氧传感器 22693-1KT0A 替换22693-1JA0A/2349127 直插式

Nissan Infiniti oxygen sensor 22693-1KT0A directly replaces 22693-1JA0A and 2349127; plug-in design requires no wiring modifications. Core function is real-time monitoring of exhaust oxygen and transmitting signals to the ECU to precisely adjust fuel injection to keep optimal air-fuel ratio. Fits models such as Teana, X-Trail, Murano, Q50, Q70. If fuel consumption rises, acceleration is weak, idle is unstable, or the engine light is on, sensor aging is indicated; replacement recovers power and reduces emissions.
