Carquest Premium – Air Conditioner Refrigerant Pressure Sensor (Part No.ACA1745)

Air Conditioner Refrigerant Pressure Sensor

from

$128.99
The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Sensor reports system pressures to the on-board computer, in turn allowing the computer to properly and efficiently control the compressor, fans and system levels. An improperly functioning A/C Pressure Sensor will provide erratic or inaccurate readings to on-board computers severely affecting system performance and function. Without reliable and accurate data from a properly functioning A/C Pressure Sensor, on-board computers are unable to protect the safety of critical components and the system as a whole which can lead to excessive wear and tear on critical components and costly system damage.

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 A/C Pressure Sensor.
  • All units are helium leak tested on fully automated mass spectrometer equipment before end-of-line testing.
  • All units are tested using automated end-of-line testing equipment that pressurizes the sensor and checks full-spectrum functionality and electrical output to ensure each part meets manufacturing specifications before packaging.

Carquest Premium – Multi-Purpose Relay (Part No.RAA1522)

Multi-Purpose Relay

from

$19.99
Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

Product Features:
  • Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
  • Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
  • Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
  • Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
  • 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
  • 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
