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

Sangyue Oxygen O2 02 Sensor 1 & 2 Kit 2PCS is a direct-fit upstream and downstream replacement set made for specific 2.4L GM models to restore accurate exhaust oxygen readings.

If your check engine light points to an O2 sensor fault or your vehicle is showing reduced fuel efficiency, this Sangyue two-piece oxygen sensor kit supplies the upstream (sensor 1) and downstream (sensor 2) components designed to fit a range of 2.4L General Motors vehicles. Each sensor ships as a pair so you replace both monitor points at once, helping the engine management system get reliable oxygen readings and maintain optimal air-fuel balance. The kit includes a one-year unlimited mileage quality guarantee and is vehicle-specific, so confirming fitment before purchase matters.

How do I install the Sangyue oxygen sensors and what locations are included?

Installation is typical for O2 sensors: locate the upstream (before the catalytic converter) and downstream (after the converter) sensor ports, remove the old sensors with an O2 sensor socket, and thread in the replacements. The kit contains both upstream and downstream sensors so you can replace both monitoring points in one service session.

• Included: two sensors — upstream (Bank 1 Sensor 1) and downstream (Bank 1 Sensor 2)
• Tools typically needed: O2 sensor socket, ratchet, anti-seize compound (if required)
• Pro tip: verify vehicle specifics (make, model, year, engine and note fields) before purchase

What should I check before buying to ensure correct fitment?

Because GM factories used different sensor assemblies and wiring across trims and production runs, confirming your exact vehicle configuration is essential. Use the seller’s compatibility check link (often labeled as an "amazonconfirmedfit" or similar) and compare make, model, year, engine size and any notes about trim to avoid buying the wrong part.

• Confirm engine: 2.4L only for the listed models
• Check exclusions: some LTZ or specific LT models are not compatible
• Use the provided compatibility tool or VIN lookup when available

What warranty and quality assurances come with the Sangyue O2 sensor pair?

Sangyue backs this two-piece sensor kit with a one-year unlimited mileage quality guarantee, which covers manufacturing defects within that timeframe. This warranty aims to give buyers confidence to install both sensors together, but normal wear-and-tear or installation damage may not be covered.

• One-year unlimited mileage quality guarantee
• Sold as an upstream + downstream pair for matching replacements
• Vehicle-specific fitment required to ensure warranty applicability

Who is this for: This Sangyue O2 Sensor 1 & 2 Kit suits owners and independent mechanics who drive or service 2.4L GM vehicles listed above and want to replace both oxygen sensors at once. It’s aimed at shoppers who prefer a direct-fit aftermarket option with a one-year quality guarantee—but buyers must confirm exact trim and year compatibility before ordering to ensure proper fit and function.
