DENSO 234-4793 Heated Oxygen Sensor Direct Fit Wire - 4-Wire 41.02

The DENSO 234-4793 is a heated, 4-wire direct-fit oxygen sensor (O2 sensor) engineered to OE-identical standards for a precise, first-time fit. With a wiring harness length of 41.02 inches and a threaded mounting type with a 0.708-inch thread diameter, this sensor is built to restore proper air-fuel mixture monitoring and emissions performance.

DENSO manufactures this sensor to the same tolerances as the original equipment part, ensuring accurate exhaust gas readings under idle, moderate acceleration, and cruise conditions. The integrated heater element brings the sensor to operating temperature quickly, supporting tighter emissions control and consistent engine management from a cold start.

Key Features:

• Direct-fit replacement — precision-engineered to OE specifications for exact installation without modification
• 4-wire heated design — integrated heater element reaches operating temperature rapidly for faster closed-loop fuel control
• 41.02" wire harness length — factory-correct pigtail length for a clean, plug-and-play installation
• Aluminum oxide trap layer — DENSO's exclusive protective coating shields the ceramic sensing element from silicone and lead contamination
• Corrosion-resistant stainless steel housing — withstands extreme exhaust heat and harsh underhood environments
• Porous PTFE filter — allows reference air to enter the sensor while blocking water and engine contaminants
• 100% tested — each unit is verified for high-temperature signal output, air tightness, continuity, and heat resistance before leaving the factory
