DASHBOARD CHECK

• Disconnect the water thermistor connector and
connect an electrical resistance (from the connector
side) between the orange/red and white/black cables.
• Turn the key to ON and verify the indication on the
dashboard.

FUEL LEVEL

DASHBOARD CHECK
• Disconnect the pump assembly connector and
connect an electrical resistance (from the connector
side) between the yellow-green and orange-black
cables.
• Turn the key to ON and verify the indication on the
dashboard.

resistance 820 Ω empty indication and indicator lit

FUEL LEVEL SENSOR CHECK

• Disconnect the pump assembly/sensor connector.
• Connect an ohm meter to terminals 2 and 3 and
verify the indication at different fuel levels.
Correct value with full tank - less than 16 Ω
Correct value with 8 litres of fuel - 300-400 Ω
Correct value with Ø litres - more than 800 Ω
