- 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.
