Denso 234-4227 Oxygen Sensor for Suzuki Esteem
Denso 234-4227 is an OE-style heated oxygen sensor built for exact replacement and first-time fit. It is engineered for 2001-2002 Suzuki Esteem downstream applications and 2001 Suzuki Esteem upstream applications, with the connector, thread, and harness layout matched to the original design.
Key Features
- OE Style oxygen sensor for direct replacement service
- Heated sensor design for faster operating response
- Specific fit for Suzuki Esteem applications
- 4-wire configuration with male connector
- Threaded mounting with 0.708 in. thread diameter
- 19.69 in. wiring harness length for factory-style routing
- Built with Denso’s aluminum oxide trap layer to help protect the sensing element from silicone and lead contamination
Product Details
This Denso oxygen sensor is manufactured and tested to OE standards for accurate replacement on the Suzuki Esteem. The heated design helps the sensor reach operating temperature quickly, while the specific-fit construction supports proper installation in the original location. Denso 234-4227 is a practical choice for drivers searching for a 2001 Suzuki Esteem upstream oxygen sensor or a 2001-2002 Suzuki Esteem downstream oxygen sensor.
This part cross-references Delphi ES20191 and NTK 24685 for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel mixture readings
- Reduced fuel economy caused by a worn sensor
- Slow sensor response during closed-loop operation
- Emissions test failures tied to sensor output issues
Installation Notes
Verify the sensor position before ordering, since this part is listed for both upstream and downstream locations on the Suzuki Esteem. Confirm the 4-wire connector, threaded mounting style, and harness length against the original sensor before installation. Use the vehicle’s factory routing and thread specification to ensure proper fitment.
Quality Assurance
Denso manufactures and tests this OE-style oxygen sensor to strict original-equipment standards. The design focuses on accurate replacement fitment, stable sensor performance, and protection of the sensing element for long service life.
