2003 Grand Caravan ES model AWD 105,000 miles
This morning after 5 minute warm up, I turned off the van and 15 minutes later I started the van again to go to work then I saw the check engine light was on that supprised me, I turned the engine off and hear the clicking sounds from under the hood, I opened the hood and found out the clicking sounds were from the Idle Air Control Motor and the ASD relay.
I did do the key dance to see what the DTC are, I got P0645,P1282,P1495.
I attach the pictures so you can see what I'm talking about.
The van still driving good as nothing happens.
So what's wrong with the van, this van totally drives me nut.
Any ideals to fix this problem.
Thank you.

You have a p0645 for a/c relay and p1282 which is a fuel pump relay code, and p1495 which is a leak detection pump code. You may have a wiring problem. Ck the wire harness by the p/s pump, i have seen the wires melt together and causes these and other codes.

 

I will check the wire hardness this week end, and how about the clicking sounds from the 2 picture, what's causing the clicking sounds?
I tried to unplug the relay and the Idle Control then pluged them back to see if the sounds goes away, but not.
Thank you

 

In most case's its a feed back thats causing the clicking sound.

 

Thanks Master Tech.
Today I just hold all the wires and pull them back and forth a few times, then suddenly the clicking sounds stopped, I ran the car couple times to see if the clicking sounds come back, but not.
I parked the car and pulled the wires couple times again to see if the clicking sounds happen again so I can spot exactly where the open/short wires are, but couldn't make it sounds again.
Well at least the car fixed for now, I'll let you know if it happens again.
Thanks again.
