Diagram Ref No 36

This coolant pipe forms part of the cooling circuit associated with the engine compressor system, providing a secure route for coolant between the relevant components. It must safely contain and transport coolant while the system is exposed to heat, pressure, vibration and repeated temperature changes.

Over time, coolant pipes, seals and connection points can deteriorate. Corrosion, physical damage, ageing seals or repeated thermal cycling may cause coolant seepage or more substantial leakage. Even a relatively minor leak can gradually reduce the coolant level and compromise cooling-system performance.

Replacing a damaged or leaking pipe with this OE Match Coolant Pipe helps restore a sealed cooling circuit, maintain dependable coolant flow and reduce the risk of overheating or associated component damage.

What This Product Does:

• Carries coolant through the relevant cooling circuit.
• Provides coolant routing for the engine compressor system where specified.
• Connects associated cooling-system components.
• Contains hot, pressurised coolant.
• Helps maintain a sealed coolant circuit.
• Supports correct coolant circulation.
• Helps regulate component operating temperatures.
• Supports effective heat transfer.
• Helps prevent coolant loss when correctly installed and sealed.
• Works alongside associated hoses, pipes, pumps and cooling components.
• Replaces a leaking, corroded or damaged coolant pipe.

LEFT Lambda Oxygen Sensor, BEFORE Catalyst, Cyl 4-6.

Restore accurate air-fuel mixture monitoring and dependable engine-management operation with this OE Match LEFT Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is specified for the LEFT side, cylinders 4–6, and is positioned BEFORE the catalytic converter.

Fits:

• Porsche 955 Cayenne 3.2L V6 2004-06  

Diagram Ref No 27

Also known as an oxygen sensor, O2 sensor or lambda probe, this component measures the oxygen content of the exhaust gases leaving the engine. As a pre-catalyst sensor, its readings provide the engine control unit (ECU) with important information about the combustion mixture before the exhaust gases enter the catalytic converter.

The ECU uses this information to determine whether the engine is operating richer or leaner than intended and can make appropriate adjustments to fuel delivery. Accurate lambda feedback helps maintain efficient combustion, smooth engine performance, controlled emissions and correct catalytic converter operation.

Located directly in the hot exhaust stream, lambda sensors endure high temperatures, vibration, thermal cycling and combustion deposits. With age, the sensing element can become contaminated or slow to respond, while the internal heater, wiring or electrical connections may also deteriorate.

This OE Match LEFT Lambda Oxygen Sensor provides a high-quality replacement for a slow, inaccurate, contaminated or failed sensor on the cylinders 4–6 bank.

What This Product Does:

• Measures oxygen content in the exhaust gases.
• Fits the LEFT-side exhaust bank where specified.
• Serves cylinders 4–6.
• Is positioned BEFORE the catalytic converter.
• Sends exhaust-mixture information to the ECU.
• Helps determine whether combustion is rich or lean.
• Supports closed-loop fuel control.
• Allows the ECU to make appropriate fuel corrections.
• Helps maintain the intended air-fuel mixture.
• Supports smooth idle and consistent engine performance.
• Helps maintain responsive acceleration.
• Contributes to efficient fuel consumption.
• Helps control exhaust emissions.
• Supports efficient catalytic converter operation.
• Replaces a faulty or slow-response pre-catalyst 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 fault codes.
• Bank-specific oxygen sensor faults for cylinders 4–6.
• Rich or lean mixture fault codes.
• Sensor heater circuit faults.
• Increased fuel consumption.
• Rough or unstable idle.
• Engine hesitation.
• Poor throttle response.
• Reduced engine performance.
• Uneven engine operation.
• Engine misfires.
• Difficult starting.
• Increased exhaust emissions.
• Failed emissions test.
• Strong fuel smell from the exhaust.
• Slow lambda sensor response during diagnostics.
• Implausible oxygen sensor readings.
• Intermittent sensor signal.
• Heat-damaged sensor wiring.
• Damaged or corroded electrical connector.  

Why Replacement Matters:

• The before-catalyst lambda sensor is an important part of the engine's fuel-management system.
• When operating in closed-loop control, the ECU uses lambda sensor information to continually refine fuel delivery. If the sensor reports inaccurate information or responds too slowly, the ECU may make inappropriate fuel corrections.
• A lambda sensor does not necessarily stop working completely when worn. It may instead become progressively slower or less accurate, which can make deterioration harder to identify without diagnostic testing.
• Replacing a confirmed faulty OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback for the cylinders 4–6 bank and allows the engine-management system to control fuelling correctly.

Lambda Oxygen Sensor, AFTER Catalytic Converter, Cyl 1-3.

Restore accurate exhaust monitoring and dependable engine-management operation with this OE Match Lambda Oxygen Sensor,. Designed for compatible Porsche applications, this sensor is positioned AFTER the catalytic converter and is specified for the exhaust bank serving cylinders 1–3.

Fits:

• Porsche 957 Cayenne 3.6L 2007-10

Diagram Ref No 31

Also known as an oxygen sensor, O2 sensor or lambda probe, this component measures the oxygen content present in the exhaust gases. Because this particular sensor is located downstream of the catalytic converter, one of its primary roles is to provide the engine control unit (ECU) with information used to monitor catalytic converter operation and overall exhaust-system performance.

The ECU compares information from sensors positioned before and after the catalytic converter. Changes in these signals allow the engine-management system to assess whether the catalyst is storing and converting exhaust pollutants as expected.

Lambda sensors operate in an exceptionally demanding environment, exposed to very high exhaust temperatures, vibration, moisture and combustion deposits. Over time, the sensing element can become contaminated or electrically degraded, while wiring and connectors may suffer heat-related damage.

This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a slow, inaccurate or failed downstream sensor.

What This Product Does:

• Measures oxygen content in the exhaust gases.
• Is positioned AFTER the catalytic converter.
• Is specified for the exhaust bank serving cylinders 1–3.
• Sends exhaust oxygen information to the ECU.
• Helps monitor catalytic converter performance.
• Allows comparison between upstream and downstream exhaust readings.
• Helps the ECU identify abnormal catalyst operation.
• Supports emissions-system diagnostics.
• Helps detect implausible exhaust sensor readings.
• Supports correct engine-management monitoring.
• Helps maintain reliable emissions-control system operation.
• Replaces a slow, contaminated 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.
• Oxygen sensor-related diagnostic fault codes.
• Catalyst efficiency-related fault codes.
• Slow or implausible downstream oxygen sensor readings.
• Intermittent sensor signal. Emissions warning messages.
• Vehicle failing an emissions test.
• Increased exhaust emissions.
• Increased fuel consumption in some circumstances.
• Rough or inconsistent engine operation where sensor faults affect control strategy.
• Damaged sensor wiring. Heat-damaged wiring insulation.
• Corroded or contaminated electrical connector.
• Sensor heater circuit fault.
• Open or short-circuit diagnostic faults.
• Sensor becoming seized in the exhaust mounting point.  

Why Replacement Matters:

• The downstream oxygen sensor provides important information about the condition and operation of the emissions-control system.
• The catalytic converter chemically converts harmful exhaust gases into less harmful emissions. To assess catalyst performance, the ECU can compare oxygen-sensor behaviour before and after the catalytic converter.
• If the downstream sensor becomes slow, inaccurate or completely inoperative, the ECU may no longer receive reliable information about catalyst operation. This can result in diagnostic fault codes and an illuminated engine-management warning light.
• A failed sensor can also make accurate diagnosis of the catalytic converter more difficult. If the ECU cannot trust the downstream sensor signal, it may be unable to distinguish reliably between a sensor problem and an actual catalyst-efficiency issue.
• Replacing a confirmed faulty OE Match Lambda Oxygen Sensor restores dependable downstream exhaust monitoring and allows the engine-management system to assess emissions-system performance correctly.

Diagram Ref No 23

Correct oil pressure is essential for engine protection. Engine oil must circulate under sufficient pressure to lubricate critical components such as crankshaft bearings, camshafts and other moving surfaces. The oil pressure sender allows the vehicle to monitor this important operating condition and alert the driver if an abnormal pressure condition is detected.

The sender operates in a demanding environment where it is exposed to hot engine oil, vibration, pressure changes and repeated heating and cooling cycles. Over time, the internal sensing mechanism, electrical connection or sealing area can deteriorate, resulting in inaccurate or intermittent pressure information.

A defective sender may produce false low-pressure warnings, implausible readings or no pressure information at all. This OE Match Engine Oil Pressure Sender provides a high-quality replacement for a confirmed faulty original component.

What This Product Does:

• Monitors pressure within the engine lubrication system.
• Converts oil pressure into an electrical signal.
• Provides oil-pressure information to applicable vehicle electronics.
• Supports engine oil-pressure warning functions.
• Helps alert the driver to potentially dangerous low oil pressure.
• Helps the engine-management or monitoring system identify abnormal pressure conditions.
• Supports reliable engine lubrication monitoring.
• Provides diagnostic information where applicable.
• Replaces an inaccurate, intermittent or failed oil pressure sender.
• Helps restore correct oil-pressure readings where displayed.
• Helps eliminate false warnings when sender failure is confirmed.
• Provides an OE Match replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Oil pressure warning light.
• Oil pressure warning message.
• Incorrect oil-pressure reading.
• Pressure gauge reading unusually high or low.
• Oil-pressure reading remaining fixed.
• Gauge fluctuating unexpectedly.
•  Intermittent oil-pressure warnings.
• Warning appearing despite verified correct mechanical oil pressure.
• Implausible oil-pressure values during diagnostics.
• Oil pressure sender-related fault codes.
• Oil leaking around the sender.
• Damaged electrical connector.
• Corroded connector terminals.
• Damaged wiring near the sender.
• Warning occurring primarily when the engine is hot.
• Pressure reading behaving inconsistently as engine speed changes.  

Why Replacement Matters:

• The oil pump circulates lubricant throughout the engine, creating the pressure necessary to maintain an oil film between moving surfaces. If actual oil pressure becomes too low, bearings and other components may no longer receive adequate lubrication.
• A correctly functioning sender allows the vehicle to provide meaningful oil-pressure information and warnings.
• If the sender itself fails, it can create false warnings or inaccurate readings. This is problematic because the driver can no longer reliably distinguish between an electrical sender fault and a genuine lubrication-system problem.
• Replacing a confirmed defective OE Match Engine Oil Pressure Sender restores reliable pressure monitoring and allows genuine oil-pressure problems to be identified more confidently.
