Buick Regal Buick Lacrosse Wuling Hongguang Intake Pressure Sensor 0261230146 12591290 Direct Replacement New

If Buick Verano, LaCrosse, or Wuling Hongguang shows rough idle, sluggish acceleration, abnormal fuel consumption, or check engine light on, the likely cause is aging/damaged intake pressure sensor. This sensor monitors absolute pressure in the intake manifold in real time and sends signals to the ECU to control fuel injection and ignition timing precisely for stable engine operation. OEM number 12591290; also compatible with 96434780, 12594942, 12644228; fits Buick Verano, LaCrosse, and Wuling Hongguang. Installation requires no adjustment other than proper sealing between sensor and intake manifold to prevent leaks.
