Welcome to the forum.

Before we can help you with that code we need to know what year it is and what repairs have been done to it recently.

Hi
Thanks for the reply.
First its a UK car manufactured in 2003 ,its a 2.0l limited and its my baby.
It turns out that the auto electrician has managed to clear the ecu so unless i get lucky the car is now spare parts. Local Chrysler garage has quoted 1600
for a new ecu ,so looking at another cruiser tomorrow and i will play around with this one.

Thanks Again

P1681: No Fuel Level Bus Message

Possible Causes:

1. Communicate With Cluster
2. Fuel Level Bus Message
3. PCI BUS Circuit Open From PCM To Instrument Cluster
4. Instrument Cluster

I would suggest checking the wiring between the Instrument Cluster and the PCM. Check all the PCM plugs for good contacts.
