Denso 234-4976 Oxygen Sensor - Downstream or Upstream Right

Denso 234-4976 Oxygen Sensor for Honda Odyssey

The Denso 234-4976 is an OE-style oxygen sensor built for exact replacement on select Honda Odyssey applications. It uses a heated, 4-wire design with a 27.17-inch wiring harness length for the specified fitment, helping restore accurate exhaust feedback for the engine management system.

Compatible with 2014-2017 Honda Odyssey downstream applications and 2016 Honda Odyssey upstream right applications, this sensor is built to match the original installation point and connector-style requirements for a direct-fit repair.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed Honda Odyssey applications
• 4-wire configuration for OE-style signal and heater control
• 27.17-inch wiring harness length
• OE Style replacement from Denso

OE Style Construction

Denso’s OE Style line is built around factory-fit replacement standards, with precision manufacturing and testing aimed at matching original equipment dimensions and performance requirements. The sensor also uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable sensor operation over time. This Denso 234-4976 oxygen sensor is a direct-fit choice for Honda Odyssey owners addressing emissions-related service needs.

This part cross-references Honda (e.g., 36532RV0A01, 36542RV0A01) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn sensor
• Reduced fuel economy caused by slow sensor response
• Emissions test failure tied to sensor output issues
• Rough engine operation from inaccurate exhaust readings

Installation Notes and Tips

Verify the sensor position before ordering: this part fits 2014-2017 Honda Odyssey downstream and 2016 Honda Odyssey upstream right locations only. Confirm the connector, harness length, and wire count against the original sensor before installation. For best results, inspect the exhaust threads and wiring routing during replacement to avoid damage to the new sensor.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for exact replacement and first-time fit. The OE-style design and contamination-resistant trap layer support consistent performance in the specified Honda Odyssey applications.
