•
Verify, with the key turned ON, the presence of voltage on the coil connector PIN 1. If no
voltage is read, verify the continuity of the cabling between coil and injection relay (No. 33
on the electrical circuit diagram): Coil PIN 1 - relay PIN 3.
•
If the above tests provided a positive result, the coil should be replaced.
Shorted to negative:
•
Disconnect the control unit connector and the coil connector.
•
Verify the coil connector PIN 3 ground insulation (or control unit connector PIN 8). Restore
the cabling if necessary.
Engine oil pressure sensor
Function:Indicates the instrument panel if there is
enough oil pressure (0.35 +/- 0.2 bar) (5.1 +/- 2.9
PSI) in the engine.
Operation / Operating principle: normally closed
switch. With oil pressure above 0.35 +/-0.2 bar (5.1
+/- 2.9 PSI), open circuit.
Level in wiring diagram:fuel reserve and oil pres-
sure.
Location:
•
sensor: between the two heads, at the
back.
•
connector: on the sensor.
Electrical characteristics:
•
With engine off: closed circuit (continu-
ity).
•
With engine started: open circuit (infin-
ite resistance).
Pin-out: Voltage 12V
Instrument panel
Warning light always off
Troubleshooting
•
Check the sensor connector and the instrument panel connector (PIN 11): If not OK, restore.
If OK, check the continuity of the purple cable between the sensor connector and the in-
strument panel connector PIN 11: if not OK, restore the cable harness; if OK, replace the
