Detailed Description

Delphi PS20073 is engineered as a manifold absolute pressure sensor for vehicles that rely on accurate intake manifold pressure data to manage fuel delivery, load calculation, and emissions-related engine control. Delphi tests and calibrates its sensors to OE standards, helping maintain consistent readings and reducing the chance of repeat repairs. This part cross-references Walker Products 225-1083 for the same application.

Search terms commonly used for this part include Delphi PS20073 MAP sensor for Volkswagen Jetta 2013-2021, Delphi PS20073 manifold absolute pressure sensor for Volkswagen Golf 2019-2021, and Audi A3 Sportback e-tron MAP sensor replacement 2016-2018.

What It Helps Address

• Incorrect manifold pressure readings
• Rough idle or unstable engine operation caused by faulty MAP signal output
• Check engine light conditions related to intake pressure sensor faults
• Fuel mixture and load calculation errors
• Emissions control performance issues tied to sensor inaccuracies

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. This sensor uses a 4-pin male terminal layout with a bolt-on design, so confirm the original part matches the connector and port configuration. Use the vehicle application data to confirm compatibility with your Volkswagen Golf, Volkswagen Jetta, Volkswagen Golf SportWagen, or Audi A3 Sportback e-tron before replacement.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for accurate readings.
