Volkswagen Jetta 2005-2012 Rear Oxygen Sensor 06A906262DM 06E906265D Cost-Effective Replacement

When a 2005-2012 VW Jetta shows check engine light on, noticeably higher fuel consumption, rough idle, or exhaust odor, typical symptoms indicate downstream oxygen sensor aging or failure. This sensor monitors exhaust oxygen content after the catalytic converter and feeds ECU to precisely adjust the air-fuel ratio for efficient engine operation and compliant emissions. This product is a high cost-performance replacement for VW Jetta (2005-2012). OEM numbers 06A906262DM and 06E906265D; fully compatible with the factory system. Installation requires clean sensor threads, use of a dedicated torque wrench to tighten to specification, avoid thread or harness damage, and disconnect the negative battery before operation to prevent short circuits.
