Breath new life into your oxygen sensor program.

What They Do:

The Oxygen Sensor (also known a Lamda sensor) is located in the exhaust manifold. It measures the amount of "unburned" oxygen in the exhaust and signals the car's onboard computer whether the mixture is too lean or too rich.

Failure Symptoms:

• High hydrocarbon emissions, failing an emissions inspection.
• The engine warming light may be on or service flag displayed.
• Excessive fuel consumption, a faulty oxygen sensor can waste 30% of fuel.
• Driveability problems, such as engine surging or hesitation.
• 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:

• Perform periodic emission checks.
• Watch for service light.
• Vehicle manufacturers recommend periodic inspection and replacement of Oxygen Sensors.
