The Lambda sensor or oxygen sensor is a sensor which provides indications concerning the oxygen
content in the exhaust gas. The signal generated is not of the proportional type but of the ON/OFF type,
i.e. there is oxygen or there is not. The sensor is positioned on the exhaust manifold before the catalytic
converter in an area where the gas temperature is always high. The temperature at which the sensor
works is at least 350°C at 600°C and it has a reaction time of just 50 milliseconds. The signal generated
passes from a high value to a low value with a mixture with lambda =1.

Check that the injection load 15A fuse No. 2 works
properly.
Check that the live control unit power supply 7.5A
fuse No. 10 works properly.
Check the efficiency of the injection load remote
control: Check the resistance of the energising coil
between pins 86 and 85: 40 to 80 Ohm
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the remote control.
