2001 ford Taurus code P1633 what does it mean and how do I fix it ?

P1633 - Keep Alive Power Voltage Too Low

Indicates that the Keep Alive Power (KAPWR) circuit has experienced a power interrupt.

Possible causes:
-Open KAPWR circuit.
-Damaged PCM.
-Intermittent KAPWR Circuit.

First thing would be to check the fuse associated with the KAP. In your case, that would be fuse #22 (10A). If you're A/C doesn't work, then that's why. Usually the A/C clutch causes the fuse to blow and your get your P1633 code.

If the fuse is fine and the A/C works, then it might be a bad PCM. If the battery was bad before it might have set this code. Have you tried clearing the codes to see if it comes back or not?

P1633 code

I have no idea why dozens of people every day, come to this site,
only wanting to clear some warning light or code

Doesn't anyone realize you have a fault in the vehicles
electrical systems, that has to be diagnosed by trained
& knowledgeable technicians, and a repair made

Google the Code & see the problem

You have a Dead Battery or Wiring issues to PCM

Study the Code

P1633---Keep Alive Power Voltage Too Low

I would suspect you have a dead battery

You did good, if you got 6 or 7 years out of it

If battery is new, there is a fuse, but that will only
set the Mil Lamp,not fix anything

P1633 code

The code indicates the battery at some point dropped below 9 volts, take your car to your local auto parts store and have them clear the code, check the battery and alternator. Most places they do this free of charge.

Hi, i have a problem with my ford escape 2001, check engine with code p1633, what are the cause tank you

Code P1633 simply means that the Keep Alive Power (KAPWR) circuit to the Engine Control Module has been interrupted. This could be due to a dead battery where you had to jump-start your vehicle or because the battery was disconnected for any reason. If your battery is hooked up and in good condition, the code will clear by itself.
