Operator Control/ Panel of Simulator
OPERATOR CONTROL - PANEL OF SIMULATOR
Signal:
Yellow connection socket for measuring the oxygen sensor voltage of all Bosch oxygen sensors.
Ground:
Blue connection socket for measuring the oxygen sensor voltage of the 4-pin oxygen sensor only.
Heating:
Red connection sockets for measuring the heating current of heated oxygen sensors. The jumper is only removed when Test # 1 is being performed. It remains installed throughout all other tests.
Level:
Yellow LED flashes when simulation in progress.
The yellow LED flashes whenever the "RICH" or "LEAN" button is pushed. This verifies oxygen sensor and oxygen sensor circuit simulation.
12V:
Green LED lights when battery voltage (>1O.5V) is applied (using 117 452).
Oxygen sensor at catalytic converter oxygen sensor at exhaust pipe:
Selector switch to select the location of the oxygen sensor.
Rich/Lean:
This button when depressed will interrupt the oxygen sensor circuit and simulate a rich or lean condition. See Test 2 & 3 for further details.
