I want to clear check engine light on 2002 jaguar xk8

You need to have the code read to find out the problem.

An OBD-II Code Reader can be purchased for about $20.

Go to http://www.jaguarforums.com/forum/xk8-xkr-17/ for specific answers to whatever problem the code identifies.

Very helpful people there at the Jaguar Forums, you should consider joining, it's FREE!

I'm not 100% sure on Jags, but on a domestic vehicle you have to clear the code with a scan tool. You should be able to call any Jaguar service center and get a quick answer.

check the PNRD safe switch located on transmission

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.
- 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.

could just be a vacuum leak or the throttle plates are dirty

A code scan will clear it.

Just a quick mention - for about a month my XK8 low coolant light came on intermittently. This week with no notice while driving normally I got Stability Control Fail and FailSafe Engine Mode and wtih great difficulty got the car back to where I started from (less than a mile). Two days later (when got time) and after a bit of research, I tried it again - same problem and a very unhappy engine. I then disconnected the battery for 15 minutes (probably more) to clear the engine codes as well as check all the wiring and vacuum stuff I could under the hood (at a Jaguar master mechanic's recommendation). No problems found but the car would start and immediately stall with the air intake hose disconnected from the intake butterfly. After I reconnected the air intake hose, she started and purred like normal. The problem is the BATTERY... It is low - I've known it for a LONG time BUT it always started right up and never skipped a beat. I intend to replace it tonight but fully expect that's the issue. I've had the car 6 years (it's a 98) and had NO problems except a dead taillight asembly.

Hope this is of value...

check that the fuel filter cap is on correctly
