Global Parts 1711586 A/C Refrigerant Temperature Sensor

A/C Refrigerant Temperature Sensor for GM HVAC Systems

Global Parts 1711586 is an A/C refrigerant temperature sensor used in HVAC control systems that monitor refrigerant temperature and relay that information to the engine management system. On modern vehicles, that feedback helps the ECM manage A/C operation; on earlier systems, it can directly signal the compressor to shut off and help prevent compressor damage.

• Type: Freon Sensor; Metric 12
• Provides refrigerant temperature feedback for A/C system control
• Supports ECM-managed compressor operation on later vehicles
• Used in compressor protection strategies on earlier systems
• Direct replacement style for select Cadillac and Oldsmobile applications

Detailed Product Information

This Global Parts A/C refrigerant temperature sensor, part number 1711586, is built for HVAC sensor applications where accurate refrigerant temperature input is required. It is a practical replacement for vehicles such as Cadillac DeVille, Cadillac Seville, Cadillac Eldorado, and Oldsmobile Aurora when the original sensor is no longer providing reliable feedback to the control system. This part cross-references Four Seasons 20047 for the same application.

Compatible With 1995-2004 Cadillac DeVille, N/A; 1995-2004 Cadillac Seville, N/A; 1995-2002 Cadillac Eldorado, N/A; 1995-1999 Oldsmobile Aurora, N/A; and 2001-2003 Oldsmobile Aurora, N/A. The part number 1711586 is also referenced in aftermarket interchange listings for related HVAC service applications.

Common Problems This Sensor Can Address

• Inaccurate refrigerant temperature feedback to the ECM
• A/C compressor cycling issues caused by a failing sensor
• Compressor shutdown triggered by incorrect temperature input
• HVAC performance problems on Cadillac DeVille and Cadillac Seville models
• Refrigerant control faults on Oldsmobile Aurora and Cadillac Eldorado vehicles

Installation Notes and Tips

Verify the connector style and sensor thread specification before installation. Compare the original sensor location and electrical connection to the replacement part number 1711586 to confirm proper fitment on your Cadillac or Oldsmobile HVAC system. After installation, clear any stored HVAC or engine management codes and confirm that the A/C system responds normally.
