What is a oxygen sensor | Oxygen Sensor |

A lambda sensor

is a lambda sensor oxygen sensor which is located in the exhaust of a Yamaha outboard motor.

The lambda sensor measures the proportion of oxygen in the exhaust gas and passes them to the CDI of the Yamaha outboard engine. The value is an indicator for the effectiveness of the combustion. Depending on the lambda value is this by the engine management system adjusted by the composition of fuel and air to adjust by the gasoline injection ratio adjust, by the injection time of the injectors to change.

lambda sensor Honda outboard motor test check:

• • Let the outboard motor between 1500-2000 RPM/per min turning the throttle by pressing forward. It is important the outboard engine with a flush clamp or

    in the water to make it run.

• • make sure you hold the throttle steady, so do not move up and down. The outboard motor would now speed stable and should not rock!

• • the engine Remains stable than there is with the lambda sensor (probably nothing to worry about. see lifetime).

• The lambda sensor gives itself a spanning on this varies between 0.1 and 0.9 volts. If you remove the plug you need outboard motor with running on the plus and minus (black and gray wire or to the black wire and the jacket) a fluctuating tension between these 0.1 and 0.9 volts. If you are measuring this value does the lambda sensor work so good.

• The heating resistance can with a disconnected plug through the white cables on the side of the lambda sensor be measured, if higher than 30 ohms should the lambda sensor be replaced.

Life span of a lambda-probe controlled:

The life span of a lambda sensor depends on various factors. Is there with the outboard many short pieces of hazards, then the life is often shorter. Pollution by motor oil (oil consumption) and poor quality gasoline also shortens the life of the lambda sensor. The operation of the lambda sensor is best with diagnostic equipment and or good multimeter/scoop.
