Detailed Description

The Holstein 2MAP3031 manifold absolute pressure sensor measures intake manifold pressure so the engine control system can calculate boost and air delivery more accurately. This matters on turbocharged gasoline and diesel vehicles where pressure feedback affects drivability, fuel control, and emissions monitoring. For Volkswagen Beetle, Golf, and Jetta models, the sensor is listed across multiple engine and VIN-specific configurations, making exact fitment verification important before ordering.

Use this Holstein Parts sensor when replacing a failed boost sensor on a Volkswagen Golf or Volkswagen Jetta, or when servicing pressure-sensor related faults on a Porsche 911 within the listed model years. The part number 2MAP3031 also cross-references Standard Ignition AS365 and URO 03G906051D.

What It Is Used For

• Incorrect boost pressure readings
• Check engine lights tied to manifold pressure or boost sensor faults
• Poor throttle response under load
• Fuel mixture or air management issues caused by inaccurate pressure data
• Emissions-related diagnostic trouble codes on listed Volkswagen and Porsche applications

Installation Notes and Tips

Confirm the vehicle’s VIN, engine code, and emissions configuration before installation, especially on 2002-2006 Volkswagen Golf and Jetta applications with multiple listed engine variants. Inspect the sensor connector, vacuum or intake tract sealing surfaces, and surrounding wiring before replacing the part. Clear diagnostic codes after installation and verify live pressure readings during a road test.

Quality Assurance

Holstein Parts 2MAP3031 is cataloged as an application-specific replacement sensor for emission control systems. Verify all fitment details against the vehicle listing and OE cross-reference before purchase.
