Sangyue Oxygen O2 Sensor Kit for 2.4L GM Vehicles — 2PCS Upstream & Downstream, Direct Replacement

The Sangyue Oxygen O2 02 Sensor 1 & 2 Kit is a two-piece upstream and downstream replacement set engineered to restore accurate air-fuel sensing for compatible 2.4L GM vehicles.

This pair of O2 sensors (one upstream, one downstream) is built as a direct-replacement option for a range of 2.4L Chevrolet, GMC, Pontiac and Saturn models. Designed to work with the vehicle engine management system, the sensors help the car’s computer measure exhaust oxygen levels so it can adjust fuel delivery and emissions controls. Before purchasing, always verify vehicle fitment details — the wrong sensor can lead to poor performance or fit issues.

Which vehicles will these Sangyue oxygen sensors fit?

These sensors are specifically made for a list of GM vehicles equipped with a 2.4L engine from model years around 2007–2014. They do not fit certain Malibu 2.4L LTZ/LT models from 2008–2010; confirm the exact engine and model notes for your car before ordering.

• Fits: 2008 Chevrolet Malibu LT/Hybrid/LS 2.4L and many 2009–2010 Malibu variants (check exclusions)
• Also fits: Pontiac G6, Saturn Vue, Saturn Sky, Saturn Aura, Pontiac Solstice with 2.4L
• Fits later models: 2010–2014 GMC Terrain and Chevrolet Equinox 2.4L, 2012–2014 Chevrolet Captiva Sport

How will replacing both upstream and downstream sensors help my vehicle?

Replacing both sensors at once ensures the engine control module receives accurate data before and after the catalytic converter. This coordinated sensing helps stabilize fuel trims, reduce false trouble codes, and maintain emissions performance compared with changing only one sensor.

• Upstream sensor measures raw exhaust oxygen for fuel control
• Downstream sensor monitors catalytic converter function
• Full-kit replacement helps prevent mismatched sensor readings

What should I check before buying the Sangyue O2 sensor kit?

Because fitment is vehicle-specific, confirm make, model, year and engine type against the seller’s compatibility chart. Also note two explicit exclusions for certain 2008–2010 Chevrolet Malibu 2.4L LTZ and 2010 Malibu LT 2.4L models; final fit depends on engine and OEM wiring connectors.

• Verify engine size: must be 2.4L for the listed models
• Cross-check model year and trim against fitment notes
• Compare connector type and sensor thread to the original unit

What warranty and quality assurances come with this pair?

Sangyue backs this two-sensor kit with a one-year unlimited mileage quality guarantee, offering replacement or support if the parts fail under normal use during that period. Keep proof of purchase and follow the seller’s return or warranty process if an issue appears.

• One-year unlimited mileage quality guarantee included
• Packaged as a 2-piece set: upstream + downstream sensor
• Sold as aftermarket direct replacements for listed GM vehicles

Who this is for: Drivers and independent mechanics who need a matched upstream/downstream O2 sensor pair for GM 2.4L vehicles listed in the compatibility guide. It’s ideal for owners diagnosing oxygen-sensor-related fault codes, replacing worn sensors to restore proper fuel trim and emissions operation, or preparing a vehicle for inspection — provided you confirm fitment against your car’s engine and trim notes.
