Diesel Injection Control Pressure Sensor

from

$164.99
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.
  • Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your injection control pressure sensor.
  • Upgraded materials compared to OE, including stainless steel housings and upgraded thermoplastics for superior corrosion resistance and high temperature performance.
  • Hermetically sealed, robotically laser-welded stainless steel housing creates a burst proof structure and superior environmental sealing protection from the elements.
  • 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.
