Product Details

The Walker Products 235-2139 crankshaft position sensor is part of the Walker Products engine sensor lineup, a product line focused on fuel system and engine management components. For Volkswagen service work, this sensor is listed for 1998-2010 Volkswagen Pointer and Pointer Truck applications, plus 2004-2005 Volkswagen Passat, 2006 Volkswagen Jetta, 2007 Volkswagen EuroVan, 2007-2009 Volkswagen CrossFox and Pointer, and 2008-2010 Volkswagen Bora. Some applications note a wire lead or sensor-only configuration, so matching the original connector style is important when ordering.

This part cross-references NGK 90565 and Dayco 87937 for the same application.

What It Helps Fix

• Crankshaft signal loss that can trigger a no-start condition
• Intermittent stalling or rough running related to crank position input
• Check engine light concerns tied to crankshaft sensor faults
• Hard starting or extended cranking on affected Volkswagen models
• Engine misfire or timing-related drivability issues caused by inaccurate sensor data

Installation Notes

Verify the original sensor style before installation, especially on listings marked with wire lead or sensor only. Confirm year, model, and engine application against the vehicle catalog before ordering. For Volkswagen Bora crankshaft position sensor replacement, Volkswagen Passat crankshaft position sensor service, and Volkswagen Jetta crankshaft position sensor repair, match the connector and routing to the original part.
