Left Oxygen Sensor for 1999-2005 Volkswagen Jetta & More - Bosch 17351

Bosch 17351 left oxygen sensor for the 1999-2002 Volkswagen Jetta V6 2.8L, the 2001-2003 Jetta 4-cylinder 2.0L, the 2001-2005 Jetta 4-cylinder 1.8L, the 2005 Jetta 4-cylinder 2.0L and other vehicles gives the ECU air-fuel data for mixture control. This Bosch O2 sensor is a wide-band type that supports fuel efficiency and reduced emissions.

• Continuous, high-precision air-fuel ratio readings across the full lambda range
• Reaches operating temperature in under 7 seconds, so the ECU gets a signal quickly for closed-loop control
• Ceramic construction and an integrated heater element with optimized control handle rapid load changes and harsh thermal cycles
• Metal housing with TSP coating resists vibration, corrosion and contamination
• Withstands exhaust streams up to 1,880°F

Quick facts

A failing wide-band sensor can show up as a check engine light, lower fuel economy or rough running. Before you replace the sensor, rule out damaged wiring or an exhaust leak ahead of it, since either can also skew the air-fuel readings; a shop can test for both. This listing is one sensor, and the 1999-2002 Jetta V6 2.8L takes one.

Fits

The 2000-2005 Volkswagen Passat 4-cylinder 1.8L, the 1999-2002 Golf V6 2.8L and the 2001-2006 Golf 4-cylinder 1.8L or 2.0L are among the vehicles it fits, so the same oxygen sensor works as a Passat oxygen sensor and as a VW Golf oxygen sensor, and it fits many other Volkswagen, Audi and Bentley models. If your car is not named here, look it up by year and engine in the "Vehicles it fits" section.
