OXYGEN SENSOR FITS HONDA CRV RE RE4 2006-2012 4 DOOR 2.4 LITRE I4 16V OX746

Description

Maintain the engine management and exhaust monitoring performance of your Honda CR-V with the OX746 Oxygen Sensor, listed for compatible Honda CR-V RE and RE4 models from 2006 to 2012 equipped with a 2.4-litre inline-four-cylinder 16-valve petrol engine.

An oxygen sensor, also known as an O2 sensor or lambda sensor, measures the oxygen content in exhaust gases and sends information to the vehicle’s engine management system. This information helps the system regulate the air-fuel mixture and monitor exhaust emissions. When the original sensor becomes slow to respond, contaminated or electrically faulty, the engine computer may receive inaccurate information that affects engine operation and emissions control.

The Honda CR-V is designed to provide practical everyday transportation, comfort and versatility. Keeping its fuel-injection and emissions systems in good condition supports dependable vehicle operation. The OX746 listing offers a replacement option for owners, mechanics, workshops and automotive parts suppliers servicing compatible CR-V models.

Because the CR-V RE range can use different sensor specifications depending on the production date, engine code and installation position, it is important to confirm the precise application before purchasing.

Vehicle Compatibility

This listing identifies the following intended vehicle application:

• Make: Honda
• Model: CR-V
• Chassis-model series: RE and RE4
• Years listed: 2006–2012, subject to exact specification
• Body style: Four-door SUV
• Engine capacity: 2.4 litres
• Engine configuration: Inline-four (I4)
• Valve configuration: 16-valve

• Product code: OX746

The CR-V RE4 is listed in automotive parts catalogues with a 2.4-litre K24Z1 four-cylinder DOHC VTEC engine for applications extending from late 2006 through 2012. Oxygen-sensor catalogues distinguish these vehicles by engine and sensor position.

The years in the product title represent the intended listing range and should not be interpreted as guaranteed fitment for every market or production variant. Before ordering, compare the vehicle identification number (VIN), engine code, original sensor part number and connector against the replacement specifications.

What Does an Oxygen Sensor Do?

An oxygen sensor measures the oxygen remaining in the exhaust after combustion. Its signal helps the engine control module assess the air-fuel mixture and adjust fuel delivery according to the vehicle’s engine-management calibration.

On compatible Honda CR-V 2.4L applications, the exhaust system may use an upstream air-fuel ratio sensor and a downstream oxygen sensor. The upstream sensor helps the engine management system control the mixture, while the downstream sensor generally monitors exhaust conditions after the catalytic converter. These sensors perform different functions and may not be interchangeable.

A properly functioning sensor provides useful feedback for engine management and emissions monitoring. However, replacing a sensor will not automatically correct every running problem. Faults in the ignition system, fuel delivery, wiring, exhaust or other engine components can produce similar symptoms.

Key Product Benefits

• Application-focused replacement: Listed for compatible Honda CR-V RE and RE4 2.4L petrol applications.
• Supports engine management: Supplies exhaust oxygen information when correctly matched and functioning.
• Assists emissions monitoring: Contributes to the system that assesses combustion and exhaust conditions.
• Useful for maintenance and repairs: Offers a replacement option when diagnostic testing confirms the original sensor is faulty.
• Helps simplify parts identification: The OX746 code makes it easier to identify the listing when ordering or managing stock.
• Supports diagnostic-led servicing: Helps technicians focus on the confirmed cause of a fault rather than replacing unrelated components.

Actual compatibility depends on the sensor’s design, electrical connector, wiring length, installation position and vehicle specification. This listing does not establish that OX746 fits every sensor position on every CR-V RE model.

Common Symptoms of a Faulty Oxygen Sensor

A failing or inaccurate oxygen sensor may contribute to the following symptoms:

• Increased fuel consumption.
• Rough or inconsistent engine idle.
• Hesitation during acceleration.
• Changes in engine response.
• An illuminated engine warning light.
• Higher-than-expected exhaust emissions.
• Diagnostic trouble codes associated with oxygen-sensor signals or heater circuits.

These symptoms are not exclusive to oxygen-sensor failure. A vacuum leak, faulty ignition component, fuel-delivery issue, damaged wiring or exhaust leak may produce similar results. A diagnostic scan and appropriate sensor-circuit checks should be completed before replacing the part.

Installation Guidelines

Correct installation helps protect the replacement sensor and its electrical connection. If you are unfamiliar with exhaust-system work, professional installation is recommended.

• Verify the application. Confirm the VIN, production date, engine code and original sensor part number.
• Identify the sensor position. Determine whether the replacement is for the upstream air-fuel ratio sensor or downstream oxygen sensor.
• Allow the exhaust to cool. Exhaust components can remain extremely hot after the engine is switched off.
• Inspect the connector and wiring. Look for corrosion, damaged insulation, heat damage or previous repairs.
• Remove the original sensor carefully. Use a suitable oxygen-sensor socket and avoid twisting or pulling the wiring harness.
• Install the replacement correctly. Follow the manufacturer’s service procedure and tightening specifications. Avoid contaminating the sensing element.
• Verify operation. Route wiring safely away from hot or moving parts and use appropriate diagnostic equipment to check the repair.

If the original sensor is seized, the connector does not match or the vehicle has a modified exhaust system, seek professional advice before proceeding.

Important Compatibility Checklist

Before purchasing OX746, confirm that:

• Your vehicle is a Honda CR-V RE or RE4 within the applicable production range.
• The engine is the specified 2.4L I4 16-valve petrol variant.
• The sensor’s connector and wiring arrangement match the original.
• The required upstream or downstream position has been identified.
• The original part number or a reliable parts catalogue confirms compatibility.
• The vehicle’s emissions configuration and any exhaust modifications have been considered.

Some vehicles require more than one exhaust sensor. Do not assume that the same replacement fits both positions, even when the connectors look similar. Confirm the required sensor location before ordering.

Conclusion

The OX746 Oxygen Sensor is listed for compatible Honda CR-V RE and RE4 four-door models from 2006 to 2012 with a 2.4-litre inline-four-cylinder 16-valve petrol engine. It is intended as a replacement option for a matching sensor application and can help support proper engine-management feedback when the original component has been diagnosed as faulty.

For the best chance of a correct fit, verify the VIN, engine code, production date, original part number, connector and exact sensor position before purchase. Correct identification and installation help support the intended engine-management and exhaust-monitoring operation of your Honda CR-V.
