日产蓝鸟/帕拉丁MAP传感器SERA48305，节气门位置精准反馈

Nissan Bluebird (2000–2006, 1.8L/2.0L) and Parading (2003–2010, 2.4L) MAP sensor SERA48305 directly monitors intake manifold pressure and provides precise feedback of manifold pressure to the ECU to optimize air-fuel ratio and ignition timing. OEM number SERA48305 can be cross-checked with original parts for compatibility. Replacement difficulty medium; use a 10mm socket to remove, clean the interface seals, and avoid leaks. A faulty sensor often leads to rough idle or reduced acceleration; bulk purchase helps reduce maintenance costs for fleets or shops.
