Im wanting to clean my Throttle Position Sensor, but Im wondering how to do it and if it needs calibration afterward. I have a 2000 Subaru Outback.

It is sealed.... I'm not sure what you are asking to do. Maybe a little more background information would make it clear what you are trying to do.

I have removed and cleaned with Caig ( Electronics Cleaner Improves the Performance and Reliability of All Electronic Equipment ) the TPS on Subaru. I have worked with electronics for well over 40 years and Caig makes the very best contact-cleaner. (Caig actually continues to clean and protect the contacts for years after application)

YES - there is a critical adjustment when reinstalling. The TPS needs to be twisted to the proper position so it is synchronized as the the throttle-valve opens. Then snug it down.

If the TPS is not properly adjusted, the computer may not know when the throttle is at 'idle' position... this can have bad affect all kinds of things. (Xmission shifting, AC performance, Battery charging.... etc)

Are you spraying the electrical cleaner in between the case and sleeve that engages the throttle shaft, allowing it to find its way into the potentiometer on the inside?
