Restore accurate air-fuel mixture monitoring and dependable engine-management performance with this OE Match Right Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is specified for the RIGHT side, BEFORE the catalytic converter.
Fits:- Porsche 955 Cayenne 3.2L V6 2004-06
Diagram Ref No 26
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor measures the oxygen content remaining in the exhaust gases immediately after combustion. It sends this information to the engine control unit (ECU), allowing the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and adjust fuel delivery accordingly.
Because this sensor is located before the catalyst, it plays an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive engine performance, appropriate fuel consumption and controlled exhaust emissions.
Lambda sensors operate in an extremely demanding environment and are continually exposed to high exhaust temperatures, vibration and combustion deposits. With age, the sensing element may become contaminated or slow to respond, while the internal heater circuit, wiring or connector can also deteriorate.
This OE Match Right Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated, damaged or failed original sensor.
What This Product Does:
- Is specified for the RIGHT-side application.
- Is positioned BEFORE the catalytic converter.
- Measures oxygen content in the exhaust gases.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the engine is running rich or lean.
- Allows continuous adjustment of fuel delivery.
- Supports accurate closed-loop mixture control.
- Helps maintain efficient combustion.
- Supports responsive acceleration and smooth engine operation.
- Helps optimise fuel consumption.
- Contributes to correct exhaust emissions.
- Helps protect the catalytic converter from problems associated with incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed oxygen sensor.
- Provides an OE Match alternative for compatible Porsche applications.
- Check engine or engine-management warning light.
- Lambda or oxygen sensor-related diagnostic codes.
- Bank-specific rich or lean mixture faults.
- Increased fuel consumption.
- Rough or unstable idle.
- Hesitation during acceleration.
- Poor throttle response.
- Reduced engine performance.
- Engine running excessively rich or lean.
- Strong fuel smell from the exhaust.
- Increased exhaust emissions.
- Failed emissions testing where applicable.
- Intermittent engine-management warnings.
- Slow sensor response during diagnostic testing.
- Implausible or inconsistent lambda readings.
- Oxygen sensor heater circuit faults.
- Damaged wiring, insulation or electrical connectors.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor is a key feedback component within the engine-management system. The ECU relies on its signal to make continual adjustments to fuel delivery as engine speed, load and operating conditions change.
- As a lambda sensor deteriorates, it can become slower or less accurate without immediately failing completely. This may result in less precise mixture control and contribute to higher fuel consumption, reduced performance, unstable running and increased emissions.
- Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust system, potentially increasing catalyst temperatures and accelerating deterioration.
- If the sensor fails completely, the ECU may substitute calculated values or adopt a fallback strategy. The vehicle may remain driveable, but performance, fuel economy and emissions can be compromised.
- Because this sensor is specified for the right-side pre-catalyst position, correct identification is especially important on engines equipped with multiple exhaust banks and lambda sensors.
- Replacing a defective component with this OE Match Right Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Information
Lambda oxygen sensor.
Fits:
Porsche 911 1984-86
Porsche 928 1983-86
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.

Blanking Plug For Oxygen Sensor Hole.
Securely seal an unused oxygen sensor port with this OE Match Blanking Plug for Oxygen Sensor Hole. Designed for compatible exhaust applications, this plug is used when an oxygen (lambda) sensor mounting hole is present but a sensor is not required for the particular vehicle, exhaust configuration, testing setup or application.

Oxygen sensor ports are threaded openings in the exhaust system that normally accommodate a lambda sensor. When the port is not being used, it must be properly sealed. Leaving the opening exposed can allow hot exhaust gases to escape and may permit moisture and contamination to enter the exhaust system.

M 18 x 1,5 x 18

Oxygen sensor ports are threaded openings in the exhaust system that normally accommodate a lambda sensor. When the port is not being used, it must be properly sealed. Leaving the opening exposed can allow hot exhaust gases to escape and may permit moisture and contamination to enter the exhaust system.
What This Product Does:
- Seals an unused oxygen or lambda sensor mounting hole.
- Prevents exhaust gases escaping through an unused sensor port.
- Helps maintain the integrity of the exhaust system.
- Protects the threaded sensor opening from dirt and contamination.
- Helps reduce moisture entering through an unused port.
- Allows an exhaust component with an oxygen sensor boss to be used where a sensor is not required.
- Provides a removable solution if an oxygen sensor is required later.
- Replaces a missing, damaged or corroded blanking plug.
- Provides an OE-style solution for compatible exhaust applications.
Symptoms Of Wear Or Failure:
- Exhaust gases leaking around the plug.
- A ticking or blowing noise from the oxygen sensor port.
- Black soot deposits around the plug or threaded opening.
- A strong exhaust smell near the affected area.
- The plug has become loose.
- Visible corrosion or deterioration.
- Damaged or stripped plug threads.
- A plug that can no longer be securely tightened.
- The original blanking plug is missing.
- An oxygen sensor has been removed and the port remains open.
- Heat or exhaust staining around the sensor boss.
Why Replacement Matters:
- An unused oxygen sensor hole should never be left open during normal engine operation. Exhaust gases are extremely hot and can escape through the opening at high velocity, potentially damaging nearby components and creating excessive noise.
- An exhaust leak can also affect the correct operation of the exhaust system. Depending on the location of the unused port and the vehicle's configuration, unwanted air entering the exhaust may also interfere with exhaust-gas measurements or diagnostic testing.
- The threaded sensor boss itself can deteriorate if left exposed. Dirt, moisture and corrosion may damage the threads, making installation of a future oxygen sensor more difficult or requiring repair of the sensor mounting point.
- A loose or damaged plug can produce similar problems. Soot deposits around the port are often an indication that combustion gases are escaping past the sealing surface or threads.
