Got all three. ..... Probally not the best combo.

If your still looking to get the P1000 code cleared; leave the PCM alone.
Everytime you clear a code, reboot etc. it resets the 1000 code.
The drive cycle is complex such that you don't just wait for cool down and go again.
There are many requirements to be met for temperatures and times. The PCM keeps track of time intervals for these tests.
Best to let it cool over and 8 hour period, begin the drive cycle with little use of braking, do accelerations and decells from different speeds.
These procedures test all the systems abilies to detect faults.
It is very hard to 'intentionaly' do this because you have no way to tell what is happening as well as the areas you drive in may not provide the sequences requires such as accelerations to 60+ in a city location etc.
For more info on all this, search for 'drive cycle' info to get the bigger picture on it, off the internet.
Just think how much of a hassle the taxi cabs have trying to clear a 1000 code in a big city!. They have to meet inspection standards same a most of the rest of us.
For an example, I had to put more than 500 mile on my truck in close to 5 different drive cycles of various lengths and it was close to the end of my inspection period to boot, to clear the 1000 code, after a coil failure..
You just have to wait it out, then one day you ckeck for the code and it's gone. Not even a dealer can clear it without doing drive cycle time.

Well i went out on the same drive as last night. I didn't get the p0232 again but thats the thing. I have been getting it off and on for about 6 months. I just have never worried about it cuase i never need to pass anything. The p1000 didn't go away either. Im guna go out and do it again tomarrow morning and post more results. Even if i pull the p1000 i shouldn't clear the DTC right. THat would start the whole process over... Right??? Thats the only code that clears it self right????

you get a p1000 that quick ? Stop rebooting on the p1000 - that was just a one shot try

I rebooted it to clear the p0232. Was i wrong. I thought that was the only way to clear that code. After that i havn't cleared the p1000. I just left it in there when i was done with the drive.

Guys your misunderstanding this relationship between codes.
The P1000 is strickly for the PIDS, that's why it does not light a CEL lamp.
There are about 8 Pids depending on the vehichle application. Sometimes not all are used.
These Pids are associated with different groups of tests and monitors.
If any one test fails under a peticular PID, that sets the code 1000.
Any detected interupption of power also set the code 1000.
The P232 is a fuel monitor action. Any failure under it's PID sets a code 1000 that then need a succesful drive cycle to clear, "after" the 232 is cleared.
For the 232 code , it can be the inertia switch contacts, fuel shut off valve monitor, bad ground, harness, short etc.
I don't envy anyone who has this kind of intermittant fault.
Good luck with it.

I thought he had a cel for p1000

I looked under fuel monitor - the code doesn't exist in my literature - maybe it's outdated. It goes from the 170's right to the low 200's which are injector codes per cylinder - from there , it goes to the 300's on the truck monitor .

So I'm confused why he has it..

I was reading that @ Scorpio - just like you said it about the valve and inertia switch .. Theres also a big ground behind the passenger side kick panel.

There a ground on the drivers side behind the kick-panel and another right above the drivers side kick panel - GREEN bolts - can't miss them . I cleaned mine up at one time.

Outside underneath the truck , there's a copper braided ground strap - 1/2 " thick . that runs from the bottom of the cab below the inertia switch and grounds on the frame..

Connector grounds are mostly Black or black w/white stripe. Pump ground is the only pink w/orange stripped ground.

Look fo bad connections..I think I have picks - hangon -

Alright ..... Lets start out with the basics taht i think i get... If you reset your computer IE take your attery out for a bit, Retune, or clear dtc's your guna get a P1000.... RIGHT???? Becuase it hasn't gone throught the "PID's". Before you even drive it the first time you will get the p1000. Then in my case as im driving i get the second code. becuase it faild to run through its "pids". So then i try and fix that code by rearanging relays and checking fuses. The easy stuff.

When i went out for my drive tonight i would have had to reswet the comp to get rid of the p0232. Otherwise when i check my comp again its still guna be there even though i fixed the problem. Right. Im not worried about the P1000. I know it clears itself out. Or at least thats what i think. The other codes dont though to my knowledge. So i have to be able to tell somehow i fixed the code and that is the only way i know of. Is there another?

To make it clear, you can reboot as much as you need to in trying to fix a DTC code fault issue.
But, this keeps the 1000 code active until the drive cycle passes all tests to auto clear the 1000 code. The only way you see the 1000 code is by reader, since it does not light the CEL lamp.
Put another way, the 1000 code is not a direct fault code but tells you that all tests had not been completed.
Most testing stations use this Pid code to pass or fail you even if there are no DTC codes present. That's why the drive cycle has to be done succesfully.
It make things difficult but that's the way it comes down from the Gov. regulatons to the mfger.
This is one way they get you for any mods that don't pass with the PCM.
They detect it but still don't know what the cause is and don't really care; you fail. Come back later and try again or whatever!
