Ford Super Duty (1999-2016) :: Code P1633 - No Power To Keep Alive Memory
Jan 6, 2014
2000 F250 4x4 V10... I am getting code P1633, no power to Keep Alive Memory
Here are the symptoms...
First, the voltmeter shows under 10 volts. When this happens, the check engine light comes on and throws code P1633.
Also, I can't shift out of park for some reason when the voltmeter shows under 10 volts.
Also, when I apply the brake, the voltmeter drops completely, no other functions seem to affect it other than applying the brake. I know this is related to the shift interlock which could have something to do with not sensing the brake is applied and won't come out of park.
What I've checked so far:
Battery has good voltage
Alternator is charging
Fuse to PCM shows good voltage
Fuses to voltmeter and shift interlock show good voltage
All grounds I've found are good
The one problem I have found is there is no power to pin 55 to PCM, Keep alive power circuit.
So, I am trying to figure out where the voltmeter gets it's signal from after the fuse box under the dash or where it is grounded, I found the shift interlock ground and it is good.
Would the fact that there is no power to pin 55 cause the voltmeter problem and shift interlock problem? I am tempted to jump power to that pin, but this will not be easy and I don't want to do it if it will just mask the real problem.
Also, when I was first experiencing this problem, the voltmeter would jump around when going over bumps while driving, then it would finally settle under 10 volts. At one time I couldn't drive the truck and kept turning it off then on in hopes it would go back to normal, I applied the parking brake then released it and let it slam up, after that it went back to normal, not sure if the jolt make a connection or what, but I would lean towards a loose connection because of the jumping around of the gauge. Now it's constant though, I messed with a ton of wiring and can't get it to go back to normal. Is there another module that has to do with any of these functions or anything that ties them all together that I am missing?
I am at a loss. I am hoping there are no drive ability issues with this problem, I'll be going on a camping trip in a couple weeks and doubt I'll have it fixed by then. I figured out how to get it out of park bypassing the shift interlock, so that's not a problem.

So I'm not sure if I bought a lemon, but i picked up a F-350 6.4 Turbo Diesel two days ago and the check engine light came on yesterday. It's giving me a P0088 Code as well as the P0088pd. It's got 131,000 miles on it so no warranty will cover me.
I'm tracking the TSB put out telling the techs to replace the HPFP, but they mention a loss of power. I've only had the truck for two days, but I've driven them for work before and I can't detect any loss of power. Besides the code, everything seems to be running fine.
What can I can try out before running out and changing the HPFP? I'd rather not cut so deep into my savings if I don't have to.

My 1999 super duty v10 has thrown a code but my scanner and a mechanics scanner won't power up and read the code, I also noticed that the cigarette lighter is dead. Which fuse controls both the plug and the lighter?

I have a 1999 Motor home has a 6.8L Triton V-10 just had a 100,000 milie tune up to include 10 new titanium spark plugs 3 months later I have this problem While driving the other day I had no power to take small hills. Little neighborhood hills were slowing me to 10 mph. Hoping its was the MAF sensor although it didn't throw a code when it was doing this but a code for PO358. So what's next back to the Ford Dealership for repairs?

I'm working on an 05 with a 5.4. I got it with a bad valvetrain noise on the PS, which ended up being a bad cam, and one bad rocker. I changed the bad rocker and any others that showed any wear, the cam, and all 12 lifters on that head.
The truck starts, idles, runs, and drives fine; identical to my own 05. But if I get on it, it has a dead spot around 3-4k rpm, then picks right up again. After a while, I get the p0012 (Variable camshaft timing over-retarded bank 1). After I get it pissed off, the idle gets rough as well and bogs down.
Now I know the cam went it correctly. I used the wedge tool so the phaser never left the timing chain. I marked the chain as well just to be safe, and the phaser only goes on the cam in one position. Also, it idles too nicely, and runs fine under normal acceleration.
Tonight I swapped the VCT solenoids from one side to the other. It took a lot longer to get the code, but finally came up as a freeze frame dtc, and on Bank 1 again, so it's not the solenoid.
So in my mind, all I can think is that the timing chain jumped (which I don't think is likely due to the good running under normal conditions), or the phaser is bad/sticking on Bank 1. I popped off the oil fill tube and the phaser looks fine physically, so I don't think I banged into it somewhere along the line. I also manually excited the Bank 1 solenoid by grounding the purple wire, and it gives my the same rough idle which I get after the p0012.
It looks like the phaser to me. Another mistake I made was not scanning the truck when I first got it. It came right from a repair shop which diagnosed the camshaft, but I would have at least known if they cleared any codes from it.

I have a 2015 SRW f350 and has been fairly problem free. Last Thursday I was driving home and I received the reduced engine power and code popped up P0088, high pressure fuel rail issue.. anyway, I just popped over 36k miles, the truck is at 36,278 miles, so I take it in thinking they will goodwill it.
I get a call saying they can't clear the code and the TCM AND PCM can't communicate and they have to reach out to Ford engineering. They find the PCM is corrupt, they call me twice and ask if the truck has been tuned, the answer is no, but then pin me against the wall saying I am the second owner, which I am, and that it could have been tuned prior. I tell them to prove it, you can see if there has been a tune. The truck truly has never been tuned, it was sold at Ford factory auction as a employee vehicle.
Now they are trying to tell me the corruption was due to the tune, which it never had. But they won't goodwill it and say I am responsible for all the diag and work done, I say no. I say this should be a warranty issue and should be covered, they say it was tuned, I told them to prove it.

I have a 2010 F250 with the V10 and 42000 miles. Lost*power*while pulling a trailer. Couldn't get over 30 mph. Tried turning back home and lost all*power*and would barely idle. Fuel filter good air filter good. Code P0300 came up. Towed it back to the house and then couldn't even get it to idle. Wouldn't throttle up past about 2800 rpm. Cleaned MAF sensor and nothing. Somewhere during all that P0174 code came up and misfire cylinder 10. Cleared codes and they haven't come back. Now when trying to crank, it barely turns over, yet battery is good. Opened air filter cover after getting it to start one time and there was some light smoke coming out. Also while barely keeping it running for a little bit, the catalytic converter on the driver side was fire hot and the other side I could grab with my hand.

I have a 2009 6.4L F250 with 153k miles on it. Yesterday I drove from downtown Dallas north to McKinney (about 40 miles) and truck was running fine. Left approx. 3 hours later for dinner and the check engine light came on and truck ran very sluggish with hardly any power. Had it checked at auto zone today and got the P040D Exhaust Gas Recirculation temperature A circuit high DTC. I can get the part but not sure if I can replace it myself.

I have been having trouble with my 2008 Ford F250 4x4, 6.4 liter diesel transmission. SCT tuner, 10" lift, egg delete and dp delete has been done. I have been losing power mainly in reverse but have noticed that the transmission hasn't always been going into the last gear on the interstate. Code PO741 would come up. The other day the shifter was stuck. So I played with it and found that the cable on the transmission had fallen off. After replacing it. The transmission wouldn't go into reverse but has been doing semi good in forward. Well I have been limping it around until today when I was going down the road and it completely stopped pulling. Now no matter what gear I place it in, it will on go in reverse. What could be causing these issues or where to even begin to start looking?

Replaced my old sagging leaf springs with new X code springs. Had an almost impossible time centering the axle even with adjustable center link. Even with it totally maxed out it is just barely centered. Now I have a terrible squeak coming from springs. Is this because of the side loading of springs? Is there any fix for it? Not only do they squeak but the drivers side now sags almost an inch even with brand new springs. 2002 F350. Super annoying and irritating

I have been trying to find a new sensor after my truck popped a P2285 code. I can't find ICP sensor at any auto parts store. I found this but it was labeled as a fuel pressure sensor on RockAuto: More Information for Standard Motor Products ICP103... Is this the same thing?

I plan to be buying a 2000 F250 V10 in a couple of hours.
I had my boss run by and take a picture of the door tag so I could determine the axle code. What he sent me was this:
Other than giving me the knowledge of how bad of a photographer he is, it doesn't tell me much else. The axle code area is blank, what gives? Am I just going to have to crawl under the truck when I get there after work?

2004 SD ext cab 5.4L Gas ! I have a mis-fire at low RPMs ! Autozone said it kicked out code P0316 Crank Position Sensor ( CPS ) but the CEL was not on ! So I replaced it and Still has the same problem. I checked the coil packs there good according to the autozone diagram "how to" ! I also pulled each wire 2 check the old shade tree way to see if I could tell that way. Now the CEL is on...

1999 F250 Super Duty 6.8 V10 4x4 157k miles
On Friday afternoon the ABS light on my dash came up, ran the codes on my SCT Livewire and came up with a "P0500 Vehicle Speed Sensor A"
What should I be going after? Rear speed sensor? Front ABS sensors? Transmission speed sensor?
Speedometer is functioning 90% of the time, twice in the last 48 hours it wouldn't then shift hard and I would pull off to reset.
I have looked over the search results and wondered if there is a way to test the sensor with my multi-meter? Seems quite a bit of people had flashing over-drive light's at the same time, which I do not.
