Lambda oxygen sensor AFTER CAT Porsche 996 / 997 / GT3
Code: 99660617801
Lambda oxygen sensor AFTER CAT Porsche 996 / 997 / GT3
porsche

Fits:
Porsche 996 C2/4 02>> (after catalytic converter)
*Cars with M661 stricter emission control concept

Porsche 997 C2/4 >>05 (after catalytic converter)

Porsche 996 GT3 MKII 04>> (after catalytic converter)


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.

About Lambda Sensors / Probes

Lambda sensors (also widely known as Oxygen sensors) on your Porsche are fitted to measure the oxygen level in the emission gasses. They are designed to help your Porsche's engine to constantly monitor the efficiency of your cats and fuel to air ratio in the intake system to help the engine run smoothly. If one of those sensors was to fail on your Porsche it could trigger poor performance and abnormally higher emissions from your engine.

It is also advised to get new oxygen sensors if you are up for a change of the exhaust system on your car as often the thread shears off and refit of old sensors is not possible.
