Denso OE Style Oxygen Sensor 234-4244
Denso 234-4244 is a specific-fit heated oxygen sensor built for direct replacement in emission control systems. It is engineered for the downstream left position on select Chevrolet Camaro, Cadillac CTS, and Cadillac STS applications, with OE-style fitment and a 4-wire male connector for straightforward integration.
Denso’s OE Style line focuses on exact replacement geometry and sensor performance. This oxygen sensor uses a threaded mounting design, a 0.708-inch thread diameter, and a 12.60-inch wiring harness length to match the original application. The sensor also incorporates Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine operation and fuel control.
