This is a problem with the alternator. Diode rectifiers and voltage regulator replacement will give this baby a 14.2 voltage output. In this 3L V6 SUV removal of the alternator requires removing the right tire, the right axis and undercovering to reach the 6G alternator. It is a 133mm rectifier with a motorcraft, The serpentine belt is better removed from the bottom. Also keep a bucket on hand to recover the oil from the transmission.

You need to remove your tyres and clean the abs sensors well enough.

You might also change your brrake pads if they have gone bad.

SOURCE: 05 ford escape wont start. jump started it and it

okay try this....talk to your parts store and get a battery load tester, and find out if the battery is indeed dead. My guess is it sounds like the Altenator is dying. they are around 50-100 and can be install by a pro in minutes.

It could be a spark plug, plug wire, or a coil. Sometimes thay break down intermittently. If it needs a tuneup, that would be the first thing to do.

This really sounds like a problem with your battery. I know you said you checked it, but is it really putting out the appropriate voltage (12.66 volts) and CCAs? Even draining the battery once can damage it (especially in cold weather), and cold weather reduces the CCAs a battery can put out. A weak battery can cause those codes. When the vehicle hesitates to start, does that typically happen on colder mornings or after the car sat for longer periods of time? I would double-check your battery. If it's the original, it's near its end of life anyway.

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 escape 2001 ,engine light on all time and code p1633 came when i did the scan ,how can i fix the problem


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.

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.

What does the code P1633 mean


P1633 Keep Alive Power Voltage Too Low (Ford/Lincoln/Mercury) It means that at sometime in the past the battery voltage was below specs at the PCM and set the code.The battery provides 12 volts to power everything,the car probably sat for a while and probably took a long time to start or had to be jumped off to start.... when the voltage got below 9 volts it set the code. The code is more of a indicator for info than anything.. the computer learns as you drive and all the code is saying is that it lost it's power to itself and can loose that learned information. Have a shop inspect the battery for being weak or dying as well as your battery connections.. if all is fine, I wouldn't worry. You can have the error reset by a mechanic or auto parts store. If you are paitent enough, the computer will reset itself over time.
