The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The injection control pressure (ICP) sensor monitors and relays the oil pressure inside the high pressure oil rails to on-board computers, helping to ensure smooth and proper fuel injector actuation and operation. Properly pressurized oil delivery is critical to the hydraulically activated electronically assisted unit injector (HEUI) fuel injection system, 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 injection control pressure sensor will provide erratic or inaccurate readings to on-board computers, severely affecting fuel injection performance and system function. Tell-tale signs of failing or failed injection control pressure sensor are rough idle and operation, power loss and the inability to start the vehicle in more severe cases.

Product Features:

The Carquest Premium line of ICP sensors offer an extremely robust design, manufactured on OE production lines. The ICP sensor kit includes all necessary components for a professional installation.
Designed and manufactured with highest quality materials, industry leading electronic components and strict quality controls. Engineered to exceed OE performance and to meet the uncompromising demands of service professionals.
