Lambda Oxygen Sensor (BEFORE Catalyst). Porsche 958 Cayenne 3.6L Petrol 2010-17  ❭  958906262S

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:

• Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17

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.  

What This Product Does:

• Monitors oxygen levels in the exhaust gases before the catalytic converter.
• Provides accurate air-fuel mixture feedback to the engine control unit.
• Optimises fuel injection and combustion efficiency.
• Improves engine performance and throttle response.
• Helps reduce fuel consumption and exhaust emissions.
• Protects the catalytic converter from incorrect fuel mixtures.
• Provides a genuine Porsche fit for straightforward installation.

Symptoms Of Wear Or Failure:

• Engine management warning light illuminated.
• Increased fuel consumption.
• Rough idle or unstable engine operation.
• Reduced engine performance or acceleration.
• Poor throttle response.
• Increased exhaust emissions.
• Failed emissions or MOT testing.
• Diagnostic fault codes relating to the oxygen sensor or air-fuel ratio.
• Premature catalytic converter deterioration caused by incorrect fuel mixture.

Why Replacement Matters:

• The pre-catalyst lambda oxygen sensor is one of the most important sensors within the engine management system, providing continuous feedback that enables the ECU to maintain the ideal air-fuel ratio. A worn or faulty sensor can cause excessive fuel consumption, reduced engine performance, rough running, increased exhaust emissions, and potential damage to the catalytic converter through prolonged rich or lean fuel mixtures.
• Replacing a worn or faulty sensor with this Genuine Porsche Lambda Oxygen Sensor (Before Catalyst) restores accurate exhaust gas monitoring, improves fuel efficiency, enhances engine performance, reduces emissions, and helps protect expensive emissions system components. Manufactured to Porsche's exacting standards, it delivers exceptional fit, precision, durability, and long-term reliability for Porsche maintenance, repairs, and restoration projects.
