The Premium CarQuest Vehicle Solutions line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The transmission oil pressure sensor monitors and relays the oil pressure inside the transmission to on-board computers, helping to ensure smooth and proper timing, shifting and operation. Properly pressurized oil delivery is critical to the transmission, and when this system fails to operate properly the on-board computers may throw a code and illuminate a check engine light. A failing or improperly functioning transmission oil pressure sensor will provide erratic or inaccurate readings to on-board computers, affecting performance and system function. Product Features:Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to exceed OE performance and to meet the uncompromising demands of service professionals.Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your transmission oil pressure sensor.All units are 100% helium leak tested on fully automated mass spectrometer equipment before end-of-line testing.All units are 100% tested using automated end-of-line testing equipment that pressurizes the sensor and checks full-spectrum functionality and electrical output to ensure each sensor meets manufacturing specifications before packaging.
