2005 Ford Freester engine running but will not drive code P1000. what is the cause of this?

The P1000 code is telling you that the diagnostics scan on van was not completed after initial scan codes were cleared and/or battery was disconnected. You will need a new scan to help pinpoint the problem which seems to possibly be a transmission sensor issue. Hope this helps-please update

If the engine light came on, there is a trouble code present. Most parts stores will scan for codes at no charge. please post codes for more information. With the tapping, I would definitely check the oil level.

My car have the code p1111 and p1646,which is that?

p1111 is nothing just letting you know system is ready after codes had been previously cleared, p1646 is 02 Sensor Control Malfuntion Bank 1 Upstream. Possible causes for p1646 o2 sensor went bad,short circuit to ground, short circuit to voltage, or open circuit. Code p1646 bank 1 sensor 1 o2 sensor control malfunction. Bank 1 is the rear bank and sensor 1 is the upstream sensor which you can see if you look between the engine inlet manifold and the brake booster(LHD). It is screwed into the manifold and has the grey connector next to the booster. You can check power to the heater on the white with green stripe wire. Any other testing will require a scan tool with datalogging capabilities. There were some VINs around your year that had their wires for that sensor twisted up by a faulty tool in the factory but you should be able to see that sort of damage easily.

P1000 JAGUAR - On Board Diagnostic System Readiness Test Not Complete, this is known as the OBD2 drive cycle.

Possible causes - The vehicle is new from the factory.

P1000 JAGUAR Description The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle.

P1000 normally is shown after the engine management light is reset.
When the light is on you should see other codes that will indicate which sensor(s) are faulty.
Most good mechanics have the equipment to read these codes and can give you a list (there may be multiple codes)
If you check out you will find further information on this subject.

Fault code P1000 [18,2,10,0],Ford Fiesta 2005

P1000 means that you or someone has disconnected the battery,and the car has not been driven far / long enough for the computer to relearn its stratagies.
Engine light could be the fault of the speed sensor, or wiring to the sensor.
