Page: 258 / 376

Install the electronic control unit interface wiring.
Start the engine and warm up until the electric fan
switches on.
Use an analogue multimeter with a direct voltage
scale measuring down to 2 V.
Connect the multimeter probes between pin 2 (-)
and pin 8 (+)
With the engine running at idle speed, check that
the voltage oscillates between 0V and 1V
With the throttle valve completely open, the volt-
age is approx. 1V.
During the closing phase, the voltage is approx.
0V.
If the voltage remains constant, the sensor may be
damaged. Remove the sensor and check that
there are no oil or carbon deposits inside it..
