Lambda sensor
The lambda sensor detects the presence of unburned fuel in the exhaust gases, processes the information
sent to the control unit and allows keeping the mixture ratio (air kg/fuel kg) within the best efficiency range
for the catalytic converter.
The vehicle is provided with two lambda sensors, one per cylinder:
- lambda sensor (1) for horizontal cylinder exhaust;
- lambda sensor (2) for vertical cylinder exhaust.
If it is necessary to reach the lambda sensor connectors, consider that:
- connector (3) of the horizontal cylinder lambda sensor is located on the vehicle front and lower side;
- connector (4) of vertical cylinder lambda sensor.
