SOURCE: 2000 Ford Windstar failed inspection for emission.

The code is "Keep Alive Power Voltage Too Low" perhaps you can find something in chilton's regarding this error. Appears to be a communication error

SOURCE: 2001 for tarous code p1633 what does that mean

P1633 means KAM (keep alive memory) power is low. The power that goes to the vehicles computer to hold its memory when the key is off has lost its power. I would start by checking fuses in the fuse panel in the engine compartment(near the radiator support). If the fuses are all good then I would test for power at the computer connector which is also in the engine compartment behind the engine. I don't have the pin number or wire color at the moment (I apologize) since the Ford website is down at the moment. I have repaired this problem in the past by installing another power wire to feed the circuit essentially bypassing the original circuit.
Hope this helps

SOURCE: ford escape 2001 ,engine light

P1633 - Keep Alive Power Voltage Too Low Indicates that the Keep Alive Power (KAPWR) circuit has experienced a power interrupt.

  • Open KAPWR circuit
  • Damaged PCM
  • Intermittent KAPWR Circuit

QB1 CHECK BATTERY TERMINALS
    Note: If KAPWR is interrupted to the PCM (that is, when a breakout box is installed or the battery is disconnected), DTC P0603/P1605 can be generated on the first power-up.
  • Inspect the battery cables for loose connections, corrosion.
Are the battery terminal connections in good condition? Yes No KEY OFF. Battery terminals are OK. GO to QB2 . REPAIR battery terminals as necessary. QB2 INSPECT ENGINE COMPARTMENT FOR PROPER WIRE ROUTING
  • Inspect Electronic Engine Control (EC) System wiring for proximity to ignition components or wires.
Is wiring too close to ignition components or wires? Yes No REROUTE as necessary. Engine compartment wire routing is OK. GO to QB3 . QB3 CHECK KEEP ALIVE POWER (KAPWR) TO PCM
    Note: Refer to the PCM connector pin numbers in the beginning of this pinpoint test.
  • Disconnect PCM.
  • Measure voltage between KAPWR circuit at the PCM harness connector and ground.
  • While observing digital multimeter, grasp the Electronic EC harness and wiggle, shake or bend a small section while working from the PCM to the dash panel.
Does the voltage reading indicate less than 10.5 volts? Yes No ISOLATE and REPAIR open circuit. No open in KAPWR harness circuit detected. GO to QB4 . QB4 CHECK FOR REPEAT OF DTC P0603/P1605/P1633
  • Reconnect PCM.
  • Start engine and allow it to reach operating temperature.
  • Run Key On Engine Off Self-Test.
  • Retrieve Continuous Memory DTCs.
Is DTC P0603, P1605 or P1633 present? Yes No REPLACE the PCM. REPAIR other DTCs as necessary. If none, testing is complete.

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?

My 1999 ford f150 has amiss fire and the p1633 code came up but the service engine light is not on


P1633 means the battery was disconnected or became discharged enough to be unable to keep the battery-backed memory in the control module alive.

If the alternator is failing intermittently, it may not always keep the battery charged enough to properly run the engine, which could cause misfires. Ensure the battery and its terminal connections are in good shape.

I am trying to connect the two facts you listed. Your facts may not be enough to find the actual cause of the misfire, however. Certainly a disconnected or otherwise discharged battery will cause the P1633 code.

Code p1633


This code means the pcm has detected a low voltage situation on the memory circuit this is a common problem in fords start by disconnecting the battery then with electrical contact cleaner pull the fuses one at a time from the fuse box under the hood clean the contacts coat with dielectric grease and replace them usually it is caused by corrosion of the contacts in this box however I have run across this where the actual wire for the memory itself has corroded to the point where it needs to be replaced from the fuse all the way to the pcm itself

Ford code P1633: Keep alve memory voltage low.
It means the voltage going to the computer fell below about 10.5 volts to set the code.
Have you experienced battery problems recently? Or had the battery disconnected?
Things to check for: bad battery, low alternator output, battery cables, and power and ground circuits to computer,

I am going to insert an Article with test procedures and it will tell you how to correct the problem.
The Code p1633 means "Keep alive power voltage too low". If you type in the captioned sentence in the Browser search box, it will pull up an Article from JustAnswer.com/Ford/18g5e-p1633 and so on. Use that site and the repair will be explained. Our pasting ability does not allow for different Formats to fit our S2008-06-02_220239_1.pngolution screen.

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.
