Description
Maintain the engine management and emissions-control performance of your Nissan Patrol with the OX762 Oxygen Sensor, listed for selected 2001–2012 Nissan Patrol ST, ST-L, ST-S and Ti GU Y61 models equipped with a 4.8-litre inline six-cylinder, 24-valve petrol engine. This replacement listing is intended for compatible applications and should be matched to the vehicle’s original sensor specifications before purchase.
An oxygen sensor, also known as a lambda sensor, measures the oxygen content in the exhaust gases and sends an electrical signal to the engine control unit (ECU). The ECU uses this information, together with readings from other engine sensors, to help regulate the air-fuel mixture and manage emissions. A sensor that has deteriorated, become contaminated or developed an electrical fault may provide inaccurate readings, potentially affecting fuel control, engine operation and emissions performance.
The Nissan Patrol Y61 is popular for touring, towing and off-road driving. Keeping its engine management system in good condition is important for reliable operation across different driving conditions. The OX762 product code helps identify this listing when searching for a replacement oxygen sensor. However, the correct sensor depends on the production date, cylinder bank and position within the exhaust system.

Parts catalogues identify multiple oxygen sensor applications for the Patrol Y61 4.8-litre TB48DE engine. These include upstream and downstream sensors, with different applications for the cylinder banks and production periods. Some replacement catalogues distinguish sensors fitted before and after early 2006, so the listed model-year range should not be treated as confirmation that one sensor fits every position.
What Does an Oxygen Sensor Do?
The oxygen sensor measures the amount of oxygen remaining in the exhaust gases after combustion. This information helps the ECU determine whether the engine is operating with the expected air-fuel mixture and make adjustments to fuel injection when required.
Depending on the vehicle’s exhaust configuration, oxygen sensors generally perform two important functions:
- Upstream sensor: Usually positioned before the catalytic converter, it provides feedback used to help regulate the air-fuel mixture.
- Downstream sensor: Usually positioned after the catalytic converter, it helps the ECU monitor catalytic converter performance and emissions-system operation.
The Patrol’s 4.8-litre engine can use multiple sensors across its exhaust system. These components may differ in electrical specifications, wiring arrangements, connector design and cable length. A sensor that looks similar to the original may still be incompatible if its signal characteristics or installation position differ.
Key Product Benefits
- Engine management feedback: Helps provide exhaust oxygen information to the ECU when correctly specified and functioning properly.
- Air-fuel mixture support: Contributes to appropriate fuel-control adjustments under normal engine management conditions.
- Emissions-system support: Helps the ECU monitor exhaust emissions and catalytic converter operation when installed in the correct position.
- Replacement option: Suitable for consideration when diagnosis confirms that the original oxygen sensor is faulty.
- Application identification: The OX762 product code helps identify this listing when comparing replacement components.
- Maintenance support: A correctly matched replacement may help restore the intended sensor feedback and support normal engine management operation.
Actual results depend on the vehicle’s condition and the underlying cause of any fault. Replacing an oxygen sensor will not repair unrelated issues such as exhaust leaks, damaged wiring, vacuum leaks, ignition faults or fuel delivery problems.
Common Symptoms of a Faulty Oxygen Sensor
A worn or malfunctioning oxygen sensor may contribute to several symptoms, including:
- The check engine warning light illuminating.
- Increased fuel consumption.
- Rough or unstable engine idling.
- Hesitation during acceleration.
- Inconsistent engine response.
- An emissions test failure.
- Diagnostic trouble codes relating to oxygen sensor signals or heater circuits.
These symptoms do not automatically confirm oxygen sensor failure. Other engine-management, fuel-system and exhaust faults can produce similar problems. A diagnostic scan, inspection of the wiring and connectors, and review of live sensor data can help identify the cause before a replacement is installed.
Installation Guidelines
Correct installation is essential for reliable sensor operation. Allow the exhaust system to cool completely before working near the sensor, as exhaust manifolds, pipes and catalytic converters can remain extremely hot after the engine has been switched off.
Before installing the OX762, follow these general checks:
- Compare the replacement sensor with the original component.
- Confirm the engine code, production date and original equipment part number.
- Identify the correct location, including upstream or downstream position and cylinder bank.
- Check the connector shape, number of wires, cable length and mounting thread.
- Inspect the wiring harness for corrosion, damaged insulation or heat exposure.
- Install the sensor according to the manufacturer’s service instructions and specified tightening torque.
- Route the wiring away from hot exhaust parts and moving components.
- Clear diagnostic codes when appropriate and verify system operation using a suitable diagnostic procedure.
Avoid pulling on the sensor wires or twisting the cable during installation. Use anti-seize compound or other thread products only when permitted by the sensor manufacturer’s instructions, as unsuitable products may contaminate the sensing element.
Professional installation is recommended if access is difficult or the original fault has not been accurately diagnosed.
Compatibility Checklist Before Purchase
To reduce the risk of ordering an incompatible part, confirm:
- Vehicle identification number (VIN).
- Exact Patrol Y61 model and production date.
- TB48DE engine specification.
- Original equipment oxygen sensor part number.
- Required sensor position and cylinder bank.
- Connector design and number of wires.
- Cable length and mounting thread.
- Emissions specification for the vehicle’s market.
Pay particular attention to the production date and cylinder bank. Parts listings distinguish some TB48DE sensor applications by build period, and front and rear sensors may also differ between the left and right sides. Confirm the original part reference before ordering.
Conclusion
The OX762 Oxygen Sensor is listed for selected 2001–2012 Nissan Patrol ST, ST-L, ST-S and Ti GU Y61 applications equipped with a 4.8-litre TB48DE inline six-cylinder, 24-valve petrol engine. As part of the engine management and emissions-control system, a correctly matched oxygen sensor helps provide the ECU with exhaust oxygen information used for fuel control and emissions monitoring.
Before purchasing, verify the original equipment part number, production date, connector and exact sensor position. When diagnosis confirms that the existing sensor is faulty, selecting the correct replacement can help restore the intended feedback function and support normal engine management performance.
