Application Details

Walker part number 250-241203 is engineered for exact vehicle placement and diagnostic response. It fits 2013 Volkswagen Jetta, center, and fits 2013-2016 Volkswagen Beetle, downstream, excluding SULEV spec and Tier 2 emissions versions. If you are searching for a Volkswagen Beetle downstream oxygen sensor or a 2013 Volkswagen Jetta center oxygen sensor, this OE-style replacement is built for those positions.

The OE Base Sensor product line is designed around original-equipment replacement requirements, with the correct connector shape, terminal count, and sensor type for the specified application. Walker part number 250-241203 is intended to restore accurate exhaust feedback to the engine management system when the original sensor has aged or failed.

What It Helps Address

• Check engine light or malfunction indicator light related to oxygen sensor faults
• Poor fuel economy caused by inaccurate air-fuel feedback
• Rough engine operation from incorrect ECU sensor input
• Elevated exhaust emissions from a degraded sensor signal
• Fault codes tied to the affected sensor circuit or related systems

Installation Notes

Confirm the connector shape, wire count, thread size, and sensor position before installation. Inspect the sensor wiring harness and connector for physical damage, since damaged wiring can shorten service life and affect operation. This oxygen sensor uses a threaded mount and is specific to the listed Volkswagen applications, so position matching is important for correct installation.

Quality Assurance

Walker Products has produced engine management and oxygen/air-fuel sensors since 1946 and operates under ISO 9001/TS 16949 certification. The OE Base Sensor line is built as an original-equipment replacement solution for the specified vehicle applications, including Volkswagen Beetle and Volkswagen Jetta fitments listed above.
