Customer Question
Hi 2001 Ram 1500...

Hi 2001 Ram 1500. Got a dead battery and P0443 code. Cleared code runs OK, but CEL comes back on same code. Have IOD of almost one AMP. IOD drops to 70ma when I pull the engine control fuse. Drain still high with PCM disconnected. Also, I noticed the power door locks operating intermittently on their own?

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

Door locks still operated on their own with fuse removed.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The code P0443 can be set by any of the following,

  • Powertrain Control Module (PCM)
  • Purge Solenoid
  • Purge Solenoid Wiring

    In order to determine which is failing you are going to need to do some testing . I have enclosed the steps in the link below, copy and paste the link to your browser to open and view it.

    The draw concern you are having is likely related to the door lock problem and the common cause for this type of problem is usually a failing Central Timer Module (CTM). Try disconnecting it and see if the draws leaves. Is so the the CTM is likely at fault.

Thanks. I forgot to say disconnecting the purge valve did not reduce the IOD. Where do I find the CTM?
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

The CTM is under the dash next to the steering column, you have to remove the panel under the column to access it. See it in the location below.

Disconnected CTM, same drain. I see in the manual that PDC fuse 3 (engine control 2) goes to PCM (the obvious suspect) fuel pump and ignition switch. I'll disconnect the PCM again tomorrow.
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

Okay post back , Im off today but will be here on Monday.

OK, so with CTM out I had the same .9A drain.
With PCM disconnected (and CTM still disconnected) the drain was lower, .6A
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

Its not likely the PCM causing the drain, have you tired pulling each fuse one at a time to try and isolate the circuit?

Customer reply replied 2 years ago
drain is on PDC fuse 3 ("engine control 2")
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

Okay then is has to something in that circuit.

Should doors lock and unlock when I pull/replace that fuse#3?
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

No they should not.

Ask Your Own Dodge Question
Customer reply replied 2 years ago
I had random power lock activity after the first dead battery. When I pull PDC#3 I still get door lock action even if the power lock (interior fuse block) is removed. So what module can operate doors locks around the fuse?
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

The door locks are controlled by the CTM.

I am not sure what to do next.
Dodge Mechanic: Ron, ASE Certified Technician replied 2 years ago

Unfortunately this type of problem is going to take some hands on testing and I can not do that from here. Something is being overlooked here and Im not sure what it is . I can open the post back up for you and see if someone else has something new to offer if you would like. Let me know.
