Default Calibrate throttle body?

Hello again. I'm considering replacing my '05 VDP throttle body due to the error codes I've gotten a couple of times (limp-home mode, etc; 85k miles).

I called Gaudin jaguar & was told that YES, it must be taken to the dealer for calibration. He was somewhat rude, so I just let it go at that. However, I find that hard to believe. Also, in reading here in the forums, it doesn't seem like it's required. Somebody on here posted to simply depress the accelerator 4-5 times & the car's computer will figure it out.

What's the real-deal answer? I hesitate to take it to a dealer, because I'm not sure that they will want to put on a part from someone else, rather, sell me theirs at 2-3 times the price.

Many thanks.

you dont need IDS or to go to the dealer. You pin the signal wires with a dvom and turn it(the TPS) to get a .6volt reading at idle. And yes you dont need the engine running or the throttle body on the car. Just the sensor hooked up and the key on, and throttle at the idle position. You can turn the TB over to access it easier.

I havn't seen him round for a while!

Funny...I just posted this on the necropost about the throttle body. To calibrate:

1). Turn the ignition on but do not start the engine.
2). Press the accelerator to the floor slowly between 3-5 seconds, and slowly release.
3). Repeat twice, for a total of 3 times

Start the are calibrated and good to go.
