Lambda Oxygen Sensor. Porsche 955 V8 BEFORE Catalytic converter - 94860612
94860612
Vehicle Group
- Porsche 955 Cayenne S 4.5L V8 2003-06
Information
Lambda oxygen sensor
Fits:
Porsche Cayenne 955 S 4.5L V8 (BEFORE catalytic converter)
Function:
The Oxygen Sensor (also known as Lambda Sensor) is located in the exhaust manifold and measures the amount of unburned oxygen in your engine's exhaust. Based on the amount of oxygen, it sends a signal to your engine computer which then adjusts the air/fuel mixture for optimum engine performance and emission control.
Failure Symptoms:
Excessive fuel consumption, a faulty oxygen sensor can waste 30% of your fuel.
Driveability problems, such as engine surging or hesitation.
High hydrocarbon emissions, failing an emissions inspection.
The engine warning light may be on or service flag displayed.
The ecu/computer stores a mixture-related fault code.
When the oxygen sensor has stopped functioning completely, the catalytic converter may overheat and fail
Maintenance/Service:
Test and/or replace every 30,000 miles.
Perform periodic emission checks.
Watch for service light.
Vehicle manufacturers recommend periodic inspection and replacement of oxygen sensor.

Information
Lambda Oxygen Sensor (BEFORE Catalyst).
Maintain optimum engine performance, fuel efficiency, and emissions control with this Genuine Porsche Lambda Oxygen Sensor (Before Catalyst), a direct replacement for 958906262S. Manufactured to Porsche's exact factory specifications, this high-precision sensor continuously monitors the oxygen content of the exhaust gases before they enter the catalytic converter. The sensor provides real-time feedback to the engine control unit (ECU), allowing precise adjustment of the air-fuel mixture for efficient combustion, maximum engine performance, and reduced exhaust emissions.
Fits:
The pre-catalyst lambda sensor is a critical component of the engine management and emissions control system. Positioned upstream of the catalytic converter, it measures the oxygen level in the exhaust stream and enables the ECU to make continuous fuel mixture corrections under all driving conditions. Manufactured using premium sensing elements within a durable, heat-resistant housing, this genuine Porsche sensor is engineered to withstand extreme exhaust temperatures, vibration, and harsh operating conditions, making it ideal for routine servicing, repairs, and emissions system maintenance.
