18075/P1667
From Ross-Tech Wiki
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 all cables 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.
