I have been watching my jag since the change of the o2 and the P1000code is always showing as pending fault when I check my codes (only code I have now). It has been this way for a few weeks now. Is this normal?

 

P1000 in a Jaguar is not a Trouble Code. It denotes "Emission Monitors Not Complete".

Several Driving Cycles will normally change it to P1111, "Emission Monitors Complete".

 

The car has been driven for 3 weeks since I starting checking for codes (when my 02 was toast)and this one has never cleared, I have not seen a P1111. Surely I have enough drive cycles by now.

 

You're not the first with this problem. Asa the cars got more sophisticated, the internal emission test became more complicated. Try this link for a start:

I do not have emission testing here so it is not a issue but the code should GO AWAY, ha ha ha

 

OK it is a nightmare to reset the codes particularly if you live on a hill. Typically it is the evap sensor that won't clear. You have to start and stay flat, you have to have about a 3/4 tank (not too full or too empty) and you can't accelerate fast (or anything that causes sloshing of the gas) will stop the cycle and the code won't clear. I finally had to take my car to the airport, park at the bottom, then wait until it got cold then driving slowly it cleared in about 3 miles. After that the rest cleared and I was good. But I spent 2 months before that driving the drive cycle over and over again on different streets with no joy. I live on a steep hill.

 

First, stop clearing codes or you go right back to step zero. Ditto if you unhook the battery.

Second, drive a few times from cold.

Next, if still P1000 look at the actual monitors for which is/are not set. The codes PDF talks about drive cycles but you might prefer to post what's not set and ask for ideas
