Give your engine computer a clean exhaust-oxygen signal with the DENSO Oxygen Sensor 234-4332. It is a direct-fit upstream replacement, whether you need a Corvette sensor for the 2005-2013 Chevrolet Corvette 6.0L / 6.2L / 7.0L or one for the 2006-2007 Chevrolet HHR 2.4L. This heated, narrow-band, 4-wire sensor threads into the exhaust in the upstream position. It reads oxygen content so the engine control module can adjust the air-fuel ratio.
- Protective housing: A laser-welded stainless housing resists corrosion. A PTFE filter blocks contaminants under harsh engine conditions.
- Dual-layer protection: Shields the ceramic element to support fast, reliable response times.
- Aluminum oxide trap layer: DENSO's exclusive layer is designed to protect the ceramic element from silicone and lead poisoning.
- Built for exact replacement: Manufactured and tested to strict OE standards, with each component precision built for a first-time fit.
Specifications: heated narrow-band sensor, 4 wires, male connector, 11.42 in wiring harness, 0.708 in thread diameter, threaded mounting and specific fit. Country of origin: United States.
The 2005-2013 Chevrolet Corvette 6.0L / 6.2L / 7.0L applications use two of these sensors per vehicle. The 2006-2007 Chevrolet HHR 2.4L application uses one sensor. See the "Vehicles it fits" section for year-by-engine details.
Signs an upstream oxygen sensor may need replacing include a check engine light, rough idle, higher fuel consumption or a failed emissions test. Other faults can cause the same symptoms, so diagnose the cause before replacing the sensor.

Frequently Asked Questions
What does the DENSO 234-4332 oxygen sensor do?
It measures oxygen in the exhaust from the upstream position and sends that signal to the engine control module, which uses it to adjust the air-fuel ratio. Its heater helps it reach operating temperature quickly.
Which vehicles does this sensor fit?
It is a direct-fit upstream sensor for the 2005-2013 Chevrolet Corvette 6.0L / 6.2L / 7.0L and the 2006-2007 Chevrolet HHR 2.4L. See the "Vehicles it fits" section for engine details.
How many of these sensors does a 2005-2013 Chevrolet Corvette 6.0L / 6.2L / 7.0L use?
The listed 2005-2013 Chevrolet Corvette 6.0L / 6.2L / 7.0L applications use two of these upstream sensors per vehicle. The 2006-2007 Chevrolet HHR 2.4L application uses one.
What are the key specifications?
It is a heated, narrow-band, 4-wire sensor with a male connector, an 11.42 in wiring harness, a 0.708 in thread diameter and threaded mounting.
What are signs an oxygen sensor may need replacing?
A check engine light, rough idle, higher fuel use or a failed emissions test may be linked to a worn oxygen sensor. Other faults cause the same signs, so diagnose the cause before replacing it.
