DENSO 234-9064 Upstream Air Fuel Ratio O2 Sensor Honda CR-V Element 2.4L For Sale

Restore optimal engine combustion, maximize fuel economy, and clear engine check lights (CEL codes such as P0134, P0135, P1157, or P2A00) with the Denso 234-9064 Upstream Air/Fuel Ratio Sensor. As an original equipment manufacturer (OEM) for Honda and Acura, Denso sensors are engineered to exact factory specifications to ensure peak performance and seamless ECU communication.

Unlike conventional narrow-band zirconia O2 sensors that only measure rich or lean conditions, the Denso 234-9064 is an advanced wideband Air/Fuel Ratio (A/F) sensor capable of continuously detecting the exact air-fuel ratio from approximately 12:1 to 19:1. Built with tarnish-proof platinum electrodes and a rapid-heating planar zirconia element, this sensor reaches operating temperature in seconds for lower cold-start emissions, smooth idle, and responsive throttle acceleration.

• Genuine OE Performance: Direct factory replacement engineered to OEM tolerances for precise ECU response and fuel trim control.

• Wideband Planar Technology: Measures real-time lambda air-fuel fluctuations across a wide spectrum for optimal horsepower and fuel mileage.

• Integrated High-Output Heater: Accelerates light-off time so the engine control module enters closed-loop operation sooner.

• Plug & Play Direct Fit: Features a factory-matched 4-pin gray connector, 14-inch wiring loom, and chassis mounting push-pin clip for effortless installation.
