Description
xTAUTOY delivers a two-piece oxygen sensor set designed for select GM 1.4L engines, pairing an upstream sensor (234-4529) with a downstream sensor (234-4528). This pair is crafted to integrate with factory wiring and mounting points, delivering OEM-grade sensing for exhaust oxygen levels across the engine management cycle.
The sensors feature a double laser-welded stainless steel body, built for durability in high-heat environments and resistance to corrosion. This construction supports high-precision measurement of oxygen partial pressure, helping the engine control module maintain a balanced air-fuel ratio as you drive through city streets and highway climbs. While results can vary by vehicle and conditions, you may notice a smoother ride and more consistent sensor signals as part of regular maintenance.
