I have a WDS unit and I need to calibrate the TPS, but I can't figure out how to do it. Usually I wander around in the menus until I find what I'm looking for, like resetting the transmission adaptations, reading DTC's or setting the ride height. I found a screen where it looked like I could monitor the TPS, but I couldn't make that work either. Is anyone familiar with this procedure?

 

this isn't the X300 where you have the set up\config special menu for the TPS.


it's self adjusting and can be manually moved around with the bolts. i'll get you my idle % in a sec

 

Hmm. I may have other problems. About eight years ago the car suddenly gave me "Engine Management Fault" along with several others and went into limp mode, where it was running about 12-1400 rpm and the throttle did nothing. I shut it off and restarted it, and it was fine. A mile later it did it again. No CEL. It did this about five times before I got it home. I did some research and everything pointed to the TPS, but at that time no one had a replacement. I pulled the connector apart, cleaned it and put some dielectric grease in it, and it was fine for two years. Then it did it again, but after the second restart it was fine. I researched it again and now people were saying it had been cross-referenced to a Denso part. I ordered one, but never got around to putting it on because I have to pull the throttle body off on this car to do it and it was working.

Now, six years later, it did it again, and it was a repeat of the previous instances. Drive a mile or two, get the fault, shut it off and restart, and go another mile or two. Naturally I couldn't find the TPS I bought six years ago so I ordered another one and the car sat for a week. One day I needed to go to the store and decided to try it, and it ran fine. I started driving it again and it was fine for two weeks, then the problem came back. Still no CEL. I parked it, got out the new TPS, and the next morning when I pulled it in the garage it was fine. I marked the TB for the position of the old TPS then changed the part. It hasn't worked since. The car starts, run normally for about two seconds, then goes into limp mode with the parade of errors, which now include a DTC. P0121 Throttle Position Sensor (TPS) circuit A low voltage and P0221 Throttle Position Sensor (TPS) circuit B low voltage, although the P0121 went away and hasn't come back. The connector seems to be in good shape, although the connector on the other side, for the throttle motor, isn't in great shape. The new TPS has the same part number as the original one, although the first one I ordered six years ago, which I found, had a different number.

 

the ebay special TPS are hit or miss

try and get one out of an x-type or s-type at the junkyard
