Don't bring it to me, I've enough to do to try to understand n look after my own LOL
I know less about the actual sensor & part concerned than Jon89, I'd say.
All I know is the complexity of trying to meet the CARB & EPA etc emissions stuff on any "interesting" car. (Bit of a vague meaning there!)
Good luck. For $2000 I do think it should now work. Hopefully the mechanic will see that has to be so, too.

Hey Bull27 -
The mechanic was stumped. Mentioned that he didn't have the equipment to re-program the throttle body. Does this make sense? My question is this -- did he not know this in the first place before he ordered the throttle body? I'm lost. I mean -- why not simply send me to the dealership to begin with? Why do a diagnostic, tell me I need a throttle body and then come back and say, "oh by the way, I do not have the equipment to re-program the throttle body." And why did it take you 40 days and 40 nights to tell me?
We are having the jag towed to the nearest dealership. If they cannot figure it out, I am going to be pretty darn pissed. But I am confident they will have a solution.
Thanks for checking up on me.

Exactly. I am baffled. He is the only mechanic in town with the equipment needed for jags. We took it to him because he has a pretty good rep in town and I asked a few people that had jags and they were pleased with him OR they travel 100 miles to the dealership I mentioned.
I honestly think that he can do minor repairs, but not anything major. I honestly feel like I have wasted my time. Something told me to go ahead and take it to the dealership. What is sad is that I haven't received a final bill (his assistant will fax it to me this afternoon). I am really going to be upset if he charged a high price for labor without actually solving the problem. The part was enough!

It does sound baffling!
You'd think he'd want to see the jon through and might (for example) have taken the car there at his own expense in order to do so if that's what's needed.
But.... maybe he's more used to older lowish-tech cars and the S-Type has been a bit of a surprise. Or something.
Going to a dealer does sound about all you can now do. Tell them everything you can about the original problem and all that's occurred, to give them the best chance to see if they agree that a replacement throttle body is actually the right fix. If you still have the original, they may wish to refit it while doing testing etc.
Good luck!

Hi Everyone!
Here's an update on my throttle body situation. I was out of town all last week on business. We had the jag towed to the dealership and they stated that the throttle body part is defective.
We are waiting to get another part shipped. It should be in one day this week.
Keep your fingers crossed that this will be the solution.

If this is for an S Type 4.0 V8, I have a brand new one in the box for $500.00. I bought it from one of the parts guys at a Jaguar dealer, they get their hands on stuff that is removed from inventory and is going to be scrapped. It has never been installed.
I don't work on S Types, but there is no need to reprogram anything after replacing a throttle body on an XJ when replacing it with the identical component.

OMG JagtechOhio!! Where were you when I needed you a month ago (or where was I? lol)....This could have saved me so much money.
I will keep you posted. I received word before I left work today that the part was delivered late afternoon. I hope this part will work. If not, I may be calling you to buy your part! However, my jag is a V6 3.0.

Update....
Well, the new part was placed on the jag and guess what? It still did not fix the problem. They are trying to figure out the problem. The mechanic mentioned that the throttle body may have burned out the ECU (what the hell is this? I have no clue...).
I am so outdone right now.

Sounds like they are trying to say that the throttle body somehow destroyed the car's main computer? Seems strange and unlikely, and expensive. How can the ECU be bad yet it works perfectly except for throwing one code? Can the throttle body be bench tested to make sure it works so that you can rule that out as a potential problem? Has anybody checked the wiring and connections from the throttle body?

I have the same DTC code; P1586. Which translates as:
TACM power supply or ground circuits: open circuit, high resistance
SCP circuit fault – U Code flagged
TACM Failure (Throttle Body failure)
It appeared after I checked and re-seated fuses and relays in order to find the fault causing only the lhs of the heated windscreen to work. All fuses had continuity. I put everything back together to be met with the message that the engine has gone into Failsafe Mode, and now it will not start. The car was running well beforehand. I did have to top up the coolant, but can't see how that might affect things.
What's going on? Any help appreciated.
