Electrical system
ELE SYS - 92
Verify continuity of the wiring harness between the sensor connector and the control unit
connector: control unit PIN 31 - sensor PIN B. If necessary, restore the wiring harness.
Verify continuity of the wiring harness between the sensor connector and the injection relay:
sensor PIN A - injection relay PIN 3. If necessary, restore the wiring harness.
If the wiring harness is intact and the error persists, proceed with the following checks.
Short circuit to negative:
Disconnect the sensor connector.
Check the sensor connector PIN B ground insulation. If there is no insulation, restore the
wiring harness.
If PIN B is insulated from ground and in the absence of other errors (fuel pump, injector,
coil), this means that the control unit is most likely faulty.
