DSC, Engine & Parking Brake Fault all at once!

![Default](/forum/images/icons/icon1.gif)
My wife was driving the car the other day and said that the car was driving fine and all of a sudden she got DSC, Engine and Parking Brake Fault all at once. The car started to sputter and would not go over 5 or 10 mph. She shut the car off and turned it back on and it went away and the same thing happened about 20mins later as she was getting to the house.
Any ideas?

I dont remember exactly what the code was but the guy at autozone said it was a throttle body sensor code and P1111.
When you guys said it might be a problem with the throttle body, I inspected it and found a crack just forward of the throttle body on the intake. Its were the tube connects to the throttle body splits off to a rectangular box that sits front and center in the engine compartment. The crack was about 2.5 inches long and .15 wide. So i sealed it up. The problem has not occurred since! I am wondering if that was the problem or will it come back again>
What do you guys think?

When 3 unrelated warning lights come on at once, my first thought is a fault in the charging/electrical system. We have had a couple Volvo wagons that would do this, and the cause was either an alternator or battery on the way out. Those cars were very sensitive to fluctuations in voltage, so the ECU would read a fluctuation as a fault. I would think that Jaguars would be the same.

Well the problem is back and I am about to lose my mind with this POS! I got the same faults just now, 4 times in a 15min drive! The sealant that i used is high temp sealant that i use on aircraft so that isn't the problem.
This car has been my worst nightmare and it only has 65k miles!
The A/C went out had to change the blower motor control module.
The car was leaking from a cracked thermostat housing, replaced that. Now its leaking coolant from somewhere else!
Both front air springs went out, replaced them! By the way my wife was parked in a spot with a concrete parking block and the car lowered it self because of the air springs and my wife without knowing backed out and almost ripped off the front bumper! Now I have to change both bumper brackets, wheel well cover panels and the bottom cover panel!
Now i have this problem, i cant take it any more! I want to blow this car up!
Is there any troubleshooting I can do so I can be sure that what im changing is the problem? Instead of just changing the throttle body, sensor or fuse box.

These cars have a large problem group but it is unusual for one car to have them all. I have an 05 and have had the suspension compressor failure but that's been it. The problem with the multiple faults at once is most likely a bad throttle position sensor in the throttle body. I suggest trying BBA Reman for repair. The sensors are not available on the retail market but they might be there for rebuilders.

As oldsmots suggests, it's most likely the throttle body. The three warnings may make no sense, but try this: disconnect either the sensor or the power cable from the TB. Turn the key to "power on" without cranking the engine and you will see these exact three warnings at the same time: "Engine system failure, DSC failure, park brake failure". Re-connect the plugs and they go away.
Also check the connectors themselves as they disintegrate over time and sometimes the contacts get coroded.
Some other thread suggested MAF could also be the source of the problem.
