My trucks giving me P1000.

From what I have read that means that its not done with a driving cycle and needs one before I check for codes, but it never clears no matter how much I drive it.
If I read codes after clearing it its still there when I check again.

I have done what that says twice, but I do not have the tool to check for pending codes.

 

It's possible your truck will ALWAYS have the P1000. (mine does). If there's no downstream O2 sensor or it's running OBD1... that'd do it.

Krewat has some tech articles about the OBD1 / OBD2 stuff on these super duties, check his stickies -

 

Check this thread out, but this is not the real answer to your problem:

On my '01, I used to get that P1000 code with my Autotap which at it's current hardware and software rev, doesn't fully "support" the 2001 V10.

If I scan it with my SCT X3 tuner, that code isn't there.

What I suspect may be happening is the scanner is "smart" (or dumb) enough that it knows the O2 sensor and catalyst monitors are reading "incomplete" (and they will NEVER complete), so it's showing you a false P1000 code.

Either that, or something with the PCM's software is befuddled and it's showing that code because the monitors have not completed, even though it shouldn't because they never will.

Again, on my '01 V10, an Autotap software setup reads a P1000 code. The SCT X3 doesn't, even on stock programming. At least, I think it doesn't.

Either the code is real, and it's the PCM showing it incorrectly, or your scanner is showing it because it doesn't see all the monitors completed.

You can ignore it. But I'd love to find out what is really causing it.

 

Thanks for stepping in here Art, I didn't want to give any false information.

On a side note, my SCT does see the P1000. I'll check to see if my aeroforce scangauge picks it up and report back.

 

ok just to confuse matters. Art your p1000 is turned off with tunes.

 

Oh, believe me I know

But I thought I didn't see the P1000 even before the tunes were installed. And I did check for it before uploading anything.

I'd hate to go back to the stock tune to find out, I've been running the 93 octane for about 6 months now and got SPOILED

It wouldn't be the first time I'm wrong though, everyone read my signature

 

Ok, thanks.

The trucks not running right and I was thinking this was part of it.

 

Hey Bill, so us a favor and put your trucks in your signature.

Not even sure what year you're talking about.

 

I'm sorry, I am really bad about not saying.

This is my 01 F350 I got with a bad engine that I am fixing up.
Its got a good engine now, but has no power at all.

I have gone over everything twice.
All I am getting now is P1000 after fixing a couple smaller things that were setting codes.

 

The P1000 is "normal". As for no power, what year engine did you use?

Do you have a datalogger/scanner than can read the MAF flow, timing, etc?

 

Remember when Mr.Pipeline had to pull the engine out of his truck with oil pressure problems and used the 06 van engine to replace it? Well, I made the drive to lubbok and got his old engine. It always had enough oil flow to keep it from being damaged and just needed the pick-up tube.

Its a 2000 engine with PI stamped heads. I don't mean " no power " like people talk about the 5.4, I really mean it has no power AT ALL.
Holding 70 MPH takes WOT with no load. Still getting better than 10 MPGs every tank even though I am on it so hard.

My truck's PO ran it with no air filter off road and a ton of little rocks ended up in the intake. One got in and bent a valve, so I was able to get the truck very cheap.

I replaced fuel and air filters, cleaned the air intake and MAF out and dropped the new V10 in with a good oil pick-up.
Everything looks good, no vacuum leaks, good fuel pressure, ect. but its still not running right.

I should be able to look at that stuff, but I don't know what it means looking at it.
If you tell me which ones to start with I'll go get it and post back with the numbers.

what I would really like to do is data log it to my laptop and post up a screen shot of it, but I can't do that becuase I broke the laptop screen and its on back order.

 

OK... now I get it

I have some datalogs laying around from playing with my SCT X3.

If you could monitor, for instance, MAF flow at WOT, and post the numbers, I can compare to what I have. Timing advance at WOT too.

 

Ok, I just got a data log showing 0-70 WOT and then 0-55 normal driving.
I have got to go to an apointment first but I will get them up as soon as I can.

Its got more power than it did before, but I don't know why.
Its also setting codes now. No CEL, but I scaned and got these:
Po300
Po303
po325
p3400

The coil and plug are both good, so I am thinking of swaping the injector on cylinder #3.
I have some extra's i can use. All the 19 lb 4.6/5.4/6.8 injectors are the same, right?

 

Is that P0340? That's the cam sensor.

I can't find a P3400 for Ford.

P0325 is knock sensor. 300 is random misfire.

I wouldn't go messing around with Cylinder #3 until you figure out why: Knock sensor is not connect, if that's a P0340 what's wrong with the cam sensor (or the wiring, given that you have both that and knock sensor) and a random misfire.

 

Yes, sorry must be P0340. The sun was putting glare on the screen when I was reading it.

I will look at the Knock sensor and cam sensor.
