C3 Picasso Electronic Problem was created by fadilabban
Hello from France
I have an electronic problem with a car that I bought, and I would appreciate your help please
Citroen C3 Picasso, Model 2011, Gasoline Engine 1.4 VTI (developed with BMW) code 8FN (EP3), 95 Horse Power, 70 Kw.
I only have these trouble codes:
P023A Water Pump Open Circuit (Controlled by the ECU by two wires)
P0597 Thermostat Open Circuit (Controlled by the ECU by two wires)
P0945 Oil Pump Open Circuit (Controlled by the ECU by two wires)
** On the scan tool I see live this live data:
Water Temperature 95 degrees celcius
Oil Pressure 5.5 bars at Idle
** I checked using a Pico Scope the two wires to each of the Water Pump, Thermostat, and Oil Pump:
I see a digital signal 3.3 volts to 14 volts on both wires Engine Running
Thanks a lot for your help
