Detailed Description

Prenco 4D-1031 is an engine crankshaft position sensor used to monitor crankshaft position and speed so the engine control system can manage ignition timing and fuel delivery. This part is a direct-fit replacement for Volkswagen Golf, Volkswagen Jetta, and Volkswagen Beetle applications listed in the fitment data, including the 2000-2001 Volkswagen Golf Brazil built vehicle application. The Prenco 4D-1031 cross-references Beck/Arnley 180-0415 and Standard Ignition PC575 for the same application.

For buyers searching by vehicle and part number, this sensor supports common replacement needs on 2000-2004 Volkswagen Jetta, 2000-2003 Volkswagen Beetle, and 2002-2004 Volkswagen Golf models. The connector layout, terminal count, and harness length are specified to match the original sensor connection points as closely as possible.

What This Sensor Helps Address

• Crankshaft position signal loss
• Intermittent stalling or no-start conditions related to crank signal failure
• Rough running caused by inaccurate engine speed input
• Check engine light concerns tied to crankshaft position sensor faults
• Hard starting after sensor or wiring degradation

Installation Notes and Tips

Verify connector shape, terminal count, and harness length against the original sensor before installation. Inspect the mating connector, wiring, and mounting area for corrosion, damage, or oil contamination before connecting the new sensor. Because the mounting bracket is not included, reuse the factory mounting arrangement where applicable and confirm the sensor seats fully at the original location.

Quality Assurance

Prenco 4D-1031 is built as an OE-style replacement sensor for the listed Volkswagen applications. Confirm fitment by year, model, and vehicle notes before ordering, especially for the 2000-2001 Volkswagen Golf Brazil built vehicle application.
