Diagram Ref No 6
Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring the amount of oxygen remaining in the exhaust, the sensor enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make the necessary fuel-delivery corrections.
Because this sensor operates upstream of the catalytic converter, it plays a particularly important role in closed-loop fuel control. Accurate readings contribute to efficient combustion, responsive engine performance, fuel economy and emissions control.
Continuous exposure to high exhaust temperatures, vibration and combustion deposits can cause lambda sensors to deteriorate over time. A worn sensor may become slow to respond, provide inaccurate readings or fail completely.
This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated or defective pre-catalytic converter sensor.
What This Product Does:
- Measures oxygen content within the exhaust gases.
- Is designed for installation before the catalytic converter.
- Sends exhaust oxygen information to the ECU.
- Helps determine whether the air-fuel mixture is rich or lean.
- Allows the ECU to continuously adjust fuel delivery.
- Supports accurate closed-loop fuel control.
- Helps maintain efficient combustion.
- Contributes to consistent throttle response and engine performance.
- Helps optimise fuel consumption.
- Supports correct exhaust emissions.
- Helps protect the catalytic converter from problems caused by incorrect fuelling.
- Replaces a slow, contaminated, damaged or failed oxygen sensor.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Lambda or oxygen sensor-related diagnostic fault codes.
- Rich or lean mixture fault codes. Increased fuel consumption.
- Rough or unstable idle. Engine hesitation or stumbling.
- 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 faults.
- Slow sensor response visible through diagnostic equipment.
- Implausible or inconsistent oxygen sensor readings.
- Sensor heater circuit faults where applicable.
- Damaged wiring or electrical connectors.
Why Replacement Matters:
- The pre-catalytic converter lambda sensor is one of the engine-management system's primary tools for controlling the air-fuel mixture.
- When operating correctly, the sensor provides rapid feedback that allows the ECU to continually adjust fuel delivery according to actual combustion conditions. If the sensor becomes slow or inaccurate, these adjustments may no longer be as precise.
- Poor mixture control can result in increased fuel consumption, reduced performance and higher emissions. In some cases, the engine may continue to operate relatively normally while efficiency gradually deteriorates.
- Incorrect fuelling can also place the catalytic converter at risk. An excessively rich mixture may allow unburned fuel to enter the exhaust system, increasing catalyst temperatures and potentially contributing to premature catalytic converter damage.
- A completely failed sensor may cause the ECU to use substitute values or a more conservative operating strategy, potentially illuminating the engine-management warning light and reducing overall efficiency.
- Replacing a defective sensor with this OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

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.

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
23mm in length
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.
