Vehicle: 2000 Jag S-type 3.0 6cyl
Mileage: 91,300

The check engine light is on and these three error codes were pulled:

• P0420 - Catalyst System Efficiency Below Threshold (Bank 1)
• P1576 - Pedal Position Not Available
• P1580 - Electronic Throttle Monitor PCM Override

Does anyone have experience with any of these? Any help or thoughts would be much appreciated.

 

To clarify the questions on the above post, we are looking for what these codes are specific to. Does each code have only one specific problem, or are there multiple things that could be wrong per each code? We recently purchased the vehicle and are new to the jaguar world.

 

These were all taken from a search on this forum.

 

If you follow the new member rules (you were told them aas part of signing up) enforced by the site you'll then be able to download things such as the codes PDFs. Yes most codes can have several causes. They're detailed in the PDFs.

 

The OBDII system is not Jaguar specific. As with all cars, codes DO NOT tell you directly what is wrong, but only point you to the component that the system detects a "out of range" reading. Example: Miss-fire codes don't automatically mean you have a bad coil. They can be caused by other issues like a vacuum leak.

You codes taken together would lead me to check for connector issues at the throttle body. Search on throttle body and you should come up with a ton of threads about it and what components to check.

Thank you for the information JOsworth and phd12volt. We appreciate your help in directing us to some possible causes and places to start.

 

I am attaching a photo with the TB plug, Remove the TB plug from the TB clean it with a contact cleaner ( I use CRC contact cleaner) make sure the electrical connections are clean and snug when installed. I hope this helps!

 

Your car is one of the early S-types and there were some issues with the throttle pedal assy. First it was the CREAKING pedal and then we had a rash of faulty PPS so there was a parts upgrade. You might need to clear the codes and if the fault returns you might need to replace the pedal assy.
