U have to complete what is called a drive cycle to clear P1000, it is a very special mixture of city and freeway driving with idleing and other driving needed to have all 5 system self test and pass. This can take a few days or a week, it depends on how u drive and where u drive, be patient it will prove out.

    the check engine lite will come back on if the fault that set code P0341 still exists after the drive cycle completes.

My car won't start and is showing a p1000 code . What does this mean?

P1000 is a manufacturer specific fault code:

Ford P1000: OBDII Monitor Testing Not Complete.
Jaguar P1000: Engine control module (ECM) - internal error.
Kia P1000: System diagnosis incomplete.
Land Rover P1000: Engine control module (ECM) memory erased - no codes stored.
Mazda P1000: OBDII Drive Cycle Malfunction.

So depending on the manufacturer of your car would depend on the meaning of a P1000 code!

What is code p1000

OBD-II Monitor Testing Incomplete

Engine misses

Hi there:
This means testing incomplete and the car needs to be driven to clear this code. Really this isn't a hard code, the causes of a P1000 include:
  • The battery or PCM has been disconnected
  • The diagnostic trouble codes have been cleared
  • An OBD monitor concern occured before completion of the drive cycle

Although this may be considered a common Ford DTC, it's very minor. You in fact can safely ignore this code and it should go away as part of normal driving, you do not need to clear this code (as it may not actually turn off the MIL). If you want to the code to clear itself, faster, run through the Ford Drive Cycle. However, if you have other trouble codes, the MIL will stay on as there are other issues.

Hope this helps.

P1000 code problem. When car has been run for awhile and shot off will not turn on until car is cold.

P1000 = Monitors incomplete. This is not a fault code it often occurs after a battery disconnect and shows that some tests have not been completed on the OBD driving cycle tests carried out automatically as the car is driven. hope this helps, please rate the answers on this site if they have been of use to you - good luck

My scan tool says p1000 when i look up the codes on my f150 just woundering what p1000 is

Hello, my name is Ben. Here is the short answer: P1000 OBD-II Monitor Testing Incomplete
P1000 will be set anytime there is any interruption of power to the PCM. This action could be but is not limited to, changing the battery, clearing history codes, or reprogramming the PCM. If there are no other codes stored the P1000 will clear itself after several "driving cycles". I hope this helps you, Ben.

Super duty fault code p1000

P1000 OBD-II Monitor Testing Incomplete

This is NOT a fault code. It is an indicator code that simply means all the self-tests have not been run yet since the last computer reset.
It's primary practical effect is to keep vehicle owner's from cheating on emissions tests.

That means there are no codes set and there aren’t enough drive cycles yet completed since the last time the codes were cleared. Once enough drive cycles have been completed you will get system passed or a fault code.

Most likely you need to take a drive, 10 minutes at highway speeds and 20 minutes at city speeds, without turning off the engine. Also while driving at city speeds there has to be several periods of stop and go.

I used an SCT livewire tuner and it came up with a trouble code of P1000. What does this code mean?

P1000 code means "testing incomplete". You can not reset this code, drive the vehicle and code should clear when the system recovers all testing data.
This can occur when the battery is disconnected for an extended period of time.
