Dreaded P1000 code.

[MarauderVOL]

I installed a tune from Reinhart and evidently I didn't drive it enough before taking it in for emissions testing. It came back with a Cat,Evap not ready in essence the computers aren't talking to each other due to the PCM not having reset. Dennis told me to return it back to stock which I have done. My wife has been driving my car back the past 2 days and has put roughly 50 miles on her on the interstate and stop and go traffic. P1000 is still showing up on the Xcal 3 tuner. What has to be done to get rid of this code? Frustrated....thanks for any suggestions

[offroadkarter]

did you try clearing it?


how long have you left the battery unplugged for?

[MarauderVOL]

I did try the clear DTC on the tuner and when I re-read the DTC it still comes up.

Sometimes you need to drive the car as much as a week to get it to clear.
It needs to see a certain amount of criteria before it turns off.

You did not need to return the car back to stock.

I had the same problem on a Crown Vic. Still hasn't gone away to my knowledge. I'm interested in what you find out... please post back up with the details. Thanks!

I'll have to check back as it's been a couple weeks for the Crown Vic.

Read this attachment about the drive cycle from the Ford manual. When I was working in dealer service most guys forgot or didn't realize the amount of fuel in the tank is VERY important inorder for proper drive cycle completion.

Why not go into scalars-misc-code_p1000_switch and set it to 0 ?

It will still know it hasnt ran through its cycles.

[FordNut]

OK, just thinking out loud.

I remember talking to a service rep about this, he showed me page off of the DMV website, and after digging around the NY vehicle inspection program website I found it again. Try These criteria:

RUNNING AN OBDII DRIVE CYCLE
The purpose of completing an OBD II drive cycle is to force the vehicle to run its onboard diagnostics. Some form of a drive cycle needs to be performed after DTCs have been erased from the PCM’s memory or after the battery has been disconnected. Running through a vehicle’s complete drive cycle will “set” the readiness monitors so that future faults can be detected (and potentially to pass the NYVIP re-inspection). Drive cycles vary depending on the vehicle and the monitor that needs to be re-set. Whenever possible, follow the drive trace prescribed for the specific vehicle/monitor in question. Some vehicle-specific drive cycles can be found in the vehicle’s Owner’s Manual.


The following “universal” drive cycle can be used as a guide to assist with re-setting monitors when a vehicle specific drive cycle cannot be located. This generic OBDII drive cycle begins with a cold start (coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another). This condition can be achieved by allowing the vehicle to “sit” overnight, and then by beginning the drive cycle the next day. Most drive cycles will be difficult to follow exactly under normal driving conditions, so the driver should exercise caution, road safety, and courtesy to others.


Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on.
Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.
Hold at a steady speed of 55 mph for three minutes.
Decelerate (coast down) to 20 mph without braking or depressing the clutch.
Accelerate back to 55 to 60 mph at ¾ throttle.
Hold at a steady speed of 55 to 60 mph for five minutes.
Decelerate (coast down) to a stop without braking.

I'm having the same problem. Failed emissions twice, for lack of communication and unsupporteds That drive cycle doc is not as easy as it seems. To much traffic to do the runs it talks about and not enough intersections without stop signs or lights. Plus i just don't do that much required highway driving. And no offense but to many LEO's about.

[ROB502]

Mine has the same code. I just thought it was the norm. and drive it like I stole it. :burnout:

My 05 Tahoe always has a code also BO229. I have it memorized because the dealer would always find it at service time. I figure the ecm is just board and looking for something to do. :cool4:

As Dennis well knows, the hardest ready monitor to pass is the canister purge. The car has to cold soak overnight and go through a cold startup. Passing all the monitors sometimes takes time.

I would just like to repeat myself with this taken from my attachment above:

Drive Cycle Recommendations
1. Most OBDII monitors will complete more readily using a "steady foot" driving style during cruise or acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
3. The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize "fuel slosh".

[MarauderVOL]

Well I've put 100 miles on her the last 3 days on the interstate and stop and go driving. Xcal 3 is still showing P1000 looks like i'm taking her to my local Ford dealer.

You are too impatient, have fun spending your money for nothing.

This is exactly what you need to do, almost to the line, I had a freind who was in the emissions repair industry and this is exactly what he did right after fixing a failed OBDII car.

+1, you can not be impatient with this, computers take time and the emissions test requires so many of the components to register prior to completing the test with a pass.

[MarauderVOL]

I just called a service tech. I really trust and he said just to drive it. So no $$ wasted as of yet. Up to 150 miles driven and no change as of yet and my tags expire tomorrow. Luckily my 1st emissions test gives me till Jan. of 09 to see if it will re-set.

[1stMerc]

In my case i don't have any codes on tuner or scanguage. So how can you tell when the pcm has reset enough to pass emissions. I drove the hell out of it last Saturday. It's already failed twice so i'd hate to pay another 24.00 to be told it failed again.

[Zack]

FYI, everytime you clear the codes in the pcm (if any) this cycle starts over from the beginning.

[1stMerc]

That's just it i didn't get any codes to begin with.
Gotta get a new PCM. Dealer couldn't get it to accept any input, not even the P1000. Even when i returned it to stock the crappy oem shift schedule didn't return. 800 smakers

[DOOM]

What exactly is the p1000 code? This just came up on my crown vic AFTER replacing my cat on the passenger side. The code for my cat was p0430. So what is p1000??? :help:

800 smackers for what? A PCM?
They list for $400 and junkyards sell them for 125-200 all day long.
I have an MAV2 computer at home.

You know dealers. Part, installation, programming. :dunno: :(

You got *****.

[1stMerc]

Yeah, that's what happens when you run out of time.
THanks for the info tho.
Maybe this will help someone else avoid it in the future.

Funny thing is i don't know what tune is in there now. Flashed it back to stock, but it doesn't have that funky oem drive and it's definitely not the way it was when i took it before i flashed it. If it wasn't for the emissions C**p i'd leave it. Gotta hook up the GPS to check speedo with the 410.s

I hope you returned your tuner back to stock before they changed the computer.

Q: What is the code P1000?

A: P1000 is not actually a trouble code. It just means that the Readiness code has not been set yet or in other words, the engine computer hasn't completed testing certain emission control components. If there is no other problems with the car emission system, the code P1000 will disappear after driving for some time (the drive circle must include idling, stop and go traffic, acceleration and steady cruising).

[MarauderVOL]

Awesome the P1000 code is gone according to the Xcal 3. It took exactly 5 days and 176 miles of interstate and city driving. I'll take it thru emissions on Mon. and then re-install the Reinhart tune. I know P1000 will then come back but I'll have a whole year to clear it out. Thanks for everyones help.

[1stMerc]

Yes i did.
