Carquest Premium – AC Pressure Sensor (Part No.ABA1074)

AC Pressure Sensor

from

$135.99
The Premium CarQuest Vehicle Solutions 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 A/C Pressure Sensor and checks full-spectrum functionality and electrical output to ensure each A/C Pressure Sensor meets manufacturing specifications before packaging
