Detailed Description

Standard Ignition AS488 is built for vehicles that use a three-terminal barometric pressure sensor to monitor atmospheric pressure as part of engine management and emissions control. Accurate barometric input helps the control system interpret load and altitude conditions, which is important for proper fuel and spark strategy. This part number, AS488, is listed for 1999-2005 Volkswagen Beetle, 1998-2004 Audi A6 Quattro, and 1998-2001 Volkswagen Passat applications.

For buyers searching for a barometric pressure sensor for Volkswagen Beetle 1999-2005, Audi A6 Quattro 1998-2004, or Volkswagen Passat 1998-2001, AS488 provides the specified connector style and terminal layout needed for the original vehicle connection. Standard Ignition AS488 is a practical replacement choice when the existing sensor has failed or is sending inaccurate pressure data.

What It Helps Address

• Incorrect barometric pressure readings
• Engine performance issues tied to faulty atmospheric pressure input
• Emission control faults related to sensor signal errors
• Driveability concerns caused by inconsistent engine management data
• Check engine light conditions linked to barometric pressure sensor failure

Installation Notes and Tips

Verify the connector style, terminal count, and terminal type before installation. AS488 uses a female connector, plug-in design, and three male blade terminals, so the replacement should match the vehicle harness exactly. Confirm the application against the vehicle year and model before service, especially on Volkswagen Beetle, Audi A6 Quattro, and Volkswagen Passat listings.

Quality Assurance

Standard Ignition parts are cataloged for service replacement use and application-specific fitment. Confirm the part number AS488 against the original sensor and vehicle identification to ensure the correct emission control sensor is selected.
