Jaguar S type R 2007 supercharged/v8 32800 Mi: charges the battery... cannot pass smog check with the message above; drove over 200 mi - no luck; tried various suggestions >3/4 of tank, on freeway, up/down hills...
Ideas? > boris.ratmansky@gmail.com; thx

 

Sounds like you need to replace 1 of the 4 O2 sensors, maybe more. Do you know the exact code?

 

Is it only the O2 sensor monitor?

Is it the Heated O2 Sensor monitor? Its drive cycle is in the code PDF, free download from stickies or it's in JTIS. (However, you have a later car so it could have changed.)

What happened that unset it? BTW, Don't be terse if you want useful replies.

Tank amount is going to be irrelevant I think.

 

Tank amount could be relevant depending on the order the car goes through the monitors. If it does its evap system monitor before the O2 sensors, than it may not run the evap monitor if the tank is below a certain fuel level, and therefore may not run the O2 sensor monitors either since they need to be done in order.

 

I was rather hoping that since he only lists one monitor that the others have set!

If not... needs a better post.
