Detailed Description

Delphi PS20126 is an emission control sensor that measures manifold pressure so the engine control module can calculate air load more accurately. This part number is engineered with OE development and validation methods, and it is calibrated to OE standards for reliable signal output. For Volkswagen Beetle, Golf, Jetta, Passat, Eos, and R32 applications, the PS20126 supports precise pressure feedback needed for proper engine management. This part cross-references Standard Ignition AS440 for the same application.

Common Issues It May Address

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine speed
• Incorrect air-fuel calculations from inaccurate pressure readings
• Hard starting or poor throttle response
• Emissions faults tied to manifold pressure signal errors

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. The Delphi PS20126 uses a 5-volt voltage signal, a black oval male connector, 4 male blade terminals, and a bolt-on design. Confirm the vehicle application by year and model before replacing the sensor. Compatible Volkswagen applications include 2012-2014 Beetle, 2010-2012 Golf, 2008-2009 Jetta, 2011-2012 Jetta, 2012 Passat, 2007-2008 Eos, and 2008 R32.

Quality Assurance

Delphi sensors are validated to OE standards and built to support accurate readings that help reduce comebacks. The PS20126 reflects Delphi’s OE-focused sensor development and calibration process for dependable replacement performance.
