18075/P1667 - Valve for Pump - Jet: Cylinder 2 (N241): Electrical Malfunction
Possible Symptoms
Irregular rpm
Possible Causes
Wiring and/or connections to/from the Valve for Pump Jet
Valve for Pump Jet
Possible Solutions
Check wiring and Check / Clean all connections
Replace the cable-tree to/from all the Valves for Pump Jet
Replace Valve for Pump Jet (replace them all !)
Special Notes
For each Valve the ECU checks the Begin of Injection Period (BIP) via a voltage. That voltage is very small (less than 0.0001A). Each extra resistance in the cable is fatal. So, in case of any doubt, just replace all cables.
