P1668 OBD Code Definition:
PCM-IDM communications error
P1668 OBD Code Description:
- Irregular rpm
- Wiring and/or connections to/from the Valve for Pump Jet
- Valve for Pump Jet
- 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 !)
- 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.
