continuity, restore the cable harness; if there is cable continuity, with the key set to KEY ON,
check the cable ground insulation (from coil connector or control unit connector). If this is
not OK, restore the cable harness.
Engine oil pressure sensor
Function:Indicates the instrument panel if there is
enough oil pressure (0.35 +/- 0.15 bar) (5.1 +/-
2.18 PSI) in the engine.
Operation / Operating principle: normally closed
switch. With oil pressure above 0.35 +/-0.15 bar
(5.1 +/- 2.18 PSI), open circuit.
Level in wiring diagram:fuel reserve and oil pres-
sure.
Location:
•
Sensor: in between the engine "V", a
little to the left, under the generator
•
Connector: on the sensor.
Pin-out: Voltage 12V
Instrument panel
Oil sensor failure DSB 07
Error cause
•
An oil sensor failure is signalled when, with engine off, it is detected that the sensor circuit
is open. The test is performed only once when the key is set to ON. This error is signalled
by the bulb icon and the general warning light turns on as well.
Troubleshooting
•
Check the sensor connector and the instrument panel connector (PIN 3, GREY connector):
if they are not OK, restore. If OK, check continuity of the purple cable between the sensor
connector and the instrument panel GREY connector PIN 3: if not OK, restore the cable
harness; if OK, replace the sensor.
Oil pressure failure DSB 08
Error cause
•
An oil sensor failure is signalled when, with engine running, it is detected that the sensor
circuit is closed. This error is signalled by the bulb icon and the general warning light turns
on as well.
Troubleshooting
•
Detach the sensor connector and check the purple cable is ground insulated: if there is
continuity to ground, restore the cable harness; if it is ground insulated, replace the switch.
