O2 Oxygen Sensor Upstream Downstream for Chevrolet Corvette (2005-2007) 6.0L

Direct-Fit Oxygen Sensor Kit for 2005-2007 Chevrolet Corvette (C6)

What it Does: This 4-sensor upstream and downstream kit monitors exhaust oxygen content on the 2005-2007 Chevrolet Corvette C6 LS2 6.0L to regulate closed-loop fueling and catalytic efficiency.

The Stock Chevrolet Corvette Sensor Failure

On the C6 Corvette equipped with the LS2 6.0L V8, factory zirconia sensors endure constant thermal cycling and exhaust heat soak. Over time, internal heater circuits burn out and ceramic sensing elements accumulate carbon or oil ash deposits. This sluggish voltage response delays closed-loop fuel trims, forcing rich default mapping and triggering P0135, P0155, P0171/P0174, or P0420/P0430 fault codes.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light / DTCs: Heater circuit and slow-response codes including P0135, P0155, or catalyst faults P0420/P0430.
• Erratic Fuel Trims: Delayed voltage switching skews fueling, causing rough idle, rich exhaust, or P0300 misfires.
• Poor Economy & Emissions Failure: Rich open-loop operation wastes fuel, overheats converters, and fails OBD-II readiness.

The Direct-Fit Matched Sensor Solution

Replacing all four sensors as a matched set restores balanced bank-to-bank air-fuel metering on the LS2 6.0L V8. Each direct-fit sensor features a corrosion-resistant stainless housing, louvered protective shield, and fast-acting internal heater calibrated to OEM voltage curves. Precision harnesses with factory-style weatherproof connectors install directly into stock exhaust bungs without cutting or splicing, replacing OEM numbers 234-4332, 234-4647, and 234-4256.

Frequently Asked Questions & Fitment Warnings

Does this fit the C6 Corvette?

Yes. Fits 2005-2007 Chevrolet Corvette models with the LS2 6.0L engine. Excludes 2008-2013 6.2L Corvettes, 7.0L Z06 models, and GM trucks; confirm engine before ordering.

Will this clear P0135, P0155, or P0420/P0430 codes?

Yes, when caused by worn sensors. New sensors restore proper switching and heater resistance, though persistent P0420/P0430 codes require checking converter health.

Is any wiring modification required for installation?

No. All four sensors feature OEM-style connectors for plug-and-play installation into factory C6 exhaust bungs.
