Strange chime coming form 2004 freestar 6cyl.

Jeff Turcotte has the diagram in an answer dated May 22 2011.
Let me know if it does not show up as a suggested answer for your question and I will copy it to you.

P0316 means misfire on the first 1,000 revolution, this is not a random misfire,or a steady misfire, it just means it there Ford has recently moved the misfire from 14000. to 1,000. It can mean the crank and cam synchonizer, a worn COP (coil on plug) COP would give a steady and exact misfire. the cranksensor itself or the harness.

I have the same problem we got the van checked there is NOTHING wrong with the engine. it just randomly beeps its a set of 5 beeps about 4 times. its seems like it could be a check engine sound but no lights are on the dash.

You did not state which engine you have in your Freestar, but here is the arrangement for the four cylinder, Come back to me if this is not correct and you have a different engine and layout.

run the fault codes
could be a low coolant level sensor so check coolant level at the tank or radiator cap

think its something to do with traction control for bad weather ,wish they made all these signs universal

go to autozone and get a free computer scan. Report back with codes. Go from there. Is light steady or flashing?

if you have a bad spark plug wire, it will draw condensation and make engine run rough.... you can check this by getting a spray bottle and filling it with water, spray a mist over top of the wires while the car is running, and if one is bad it will show.... (looks like little lightning coming off of wire) .... hope this helps

it sounds like you need to adjust your doors to close tighter or you have a bad door ajar switch which may be part of the latch.

We stopped guessing about causes back in '96 when cars stored trouble codes. Get the codes read and post them. Then we can help
