Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.
drive it. I am betting you have recently "cleared" codes which also clears readiness monitors in an attempt to better control people cheating the system. After enough drive cycles are reached the monitors will pass if nothing is wrong and turn to ready. If the problem that the codes implicated where not fixed than the check engine light will again come back on and you will again fail your attempt to pass emissions.
Is the check engine light displayed? If it is, that's where you start, by retrieving the fault code(s). If not, then you could have a security system fault, fuel system breakdown, etc. All codes, regardless of the systems affected, will cause the vehicle computer to immediately default to a failsafe mode, till the problem has been fixed, and this drastically affects driveability, causing no-start issues, idle problems, etc.
broken evap line/port on fuel pump. Or leaking fuel pump o-ring
check the EVAP canister it is right next to fuel filter could be pcm needs update to fix false codes. Here is a old hillbilly trick that may help put saliva on the seal of gas cap when you fill up every time that may work for you.
Is there a specific code that has come up and turned on the check engine light?
The EVAP emissions system collects the fuel vapor from your fuel tank and stores them in the charcoal canister. While you are driver the computer cycles the EVAP purge solenoid which places the EVAP system and gas tank under a slight vacuum. This pulls or "purges" those stored vapors out if the charcoal canister and let's them burn off through the engine.
P1000 JAGUAR - On Board Diagnostic System Readiness Test Not Complete, this is known as the OBD2 drive cycle.
- The vehicle is new from the factory. - Battery or Powertrain Control Module (PCM) had recently been disconnected. - An OBD monitor failure occurred before completion of an OBD drive cycle. - PCM Detected Trouble Codes (DTC) have recently been cleared with a scan tool. When is the code detected?
If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared.
P1000 JAGUAR Description
The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.
This code is an indication that the transmission has excessive slippage, the code is for the input and output turbine speed sensors, based on what i know of this problem the trans has a mechanical problem, that would be low fluid pressure or worn out forward clutches, make sure the trans fluid is not low, if it is ok you will need to have the trans torn down for inspection..
The trick to setting all the monitors is:
Make sure you have more than 1/4 tank of fuel but no more than 3/4.
Clear codes then Do Not cycle key off. Start vehicle and drive,make sure you do at least 2 minutes of steady spead between 40-50 mph and at least 2 minutes at 50-65 mph, usually about a 20 to 25 mile drive will set them..
If you turn the ignition off before the monitors complete then EVAP will have to see a 6 hour cold soak before it will attempt to run again.
