Global Parts 1711741 HVAC Pressure Transducer

HVAC Pressure Transducer Overview

Global Parts 1711741 is an HVAC pressure transducer used to send pressure feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier systems, it can help shut the compressor off before damage occurs. This HVAC pressure transducer is a direct-fit service part for select GM applications, including Chevrolet Cavalier, Pontiac Sunbird, and Buick Skylark.

Key Features

• HVAC pressure transducer for A/C system pressure feedback
• Supports ECM-controlled air conditioning operation
• Used in system-mounted pressure transducer applications
• Direct replacement for select GM vehicles
• Global Parts Part Number: 1711741
• Cross-reference: 22599559, SW-200

Detailed Description

Global Parts 1711741 is built for vehicles that rely on an electrical pressure switch to report A/C system pressure to the control module. That signal helps the ECM regulate compressor operation and protect the system from pressure-related failure. It is a practical replacement for service work on GM platforms such as the Chevrolet Cavalier, Chevrolet Corsica, Chevrolet Lumina, Pontiac Grand Am, Pontiac Grand Prix, and Buick Regal.

Common Problems This Part Can Address

• Inaccurate A/C pressure signal to the ECM
• Compressor cycling issues caused by a failed transducer
• A/C shutdown triggered by pressure sensor faults
• Loss of compressor protection logic in system-mounted applications
• Intermittent air conditioning operation on select GM vehicles

Installation Notes and Tips

Verify the original connector style and system-mounted location before installation. Compare the removed part number and vehicle application against the listed fitment for Chevrolet Cavalier, Pontiac Sunbird, and other supported GM models. After installation, confirm A/C system operation and check for stored HVAC or ECM fault codes.

Quality Assurance

Global Parts 1711741 is engineered for the listed GM applications and follows the pressure-feedback function required by the vehicle control system. Confirm fitment by year, make, and model before ordering.
