CAT not Ready- P1000
Thanks for replying. Wouldn't i get a bad o2 sensor code if there was an issue with them? Only code is P1000 (CAT not ready). I read the drive cycle in structions and would need to be on a closed track to do that. Insane.

Follow the link below and go to post #4 and print out the procedure for clearing monitors especially cats.
Be sure to follow each step and it should set if there are no DTC's on the scan tool.

here is what i picked up from Jaguar service manual:
JAGUAR EMS: ON BOARD DIAGNOSTICS REVIEW
Service Training
OBD.9
Student Guide
OBD II Drive Cycle
This is a very specific combination of driving conditions that have been set out by the Federal Clean Air Act adhering
to Federal Test Procedure 75 (FTP 75). Completion of all the conditions of this cycle ensures that all monitors
have completed their required tests. This cycle is the most comprehensive of all the cycles.
In order for all monitors to take place the following must happen:
Connect the Scan Tool or PDU to the DLC. Switch ignition on. Start the engine. Once started, the engine must not
be turned off at any time during the drive cycle.
1. Allow the engine to idle or drive the vehicle for at least
4 minutes
until it is warmed up to a temperature of
180°F.
2. Idle for
45 seconds.
3. Accelerate to 45 MPH at 1/4 throttle (elapsed time is about
10 seconds
).
4. Once 45 MPH is realized, decelerate vehicle speed to approximately 35 MPH
5. Drive at a speed between 30 and 40 MPH, maintaining a steady throttle position for at least one minute.
6. Decelerate to a speed above 20 MPH.
7. Drive until at least four minutes are spent between 20 and 45 MPH. Do not operate at WOT.
8. Decelerate and idle for at least 10 seconds.
9. Accelerate to 55 MPH at 1/2 throttle (elapsed time should be about 10 seconds).
10. Cruise at a speed between 45 and 55 MPH, maintaining a steady throttle position for at least
80 seconds.
Do
not exceed posted speed limit.
11. Decelerate vehicle and stop.
12. Bring vehicle down to idle.
13. Check scan tool for on-board system readiness test results and any DTCs.
