I'm experiencing all of the symptoms of a failing TPS on my 2005 Corolla S (car has 650,000 kms). Part isn't expensive and looks easy to get to so figured I'd replace it. However, the Haynes manual says "on 2005 and later models the throttle body is operated by an electric throttle control motor instead of a cable. On these models the TPS is part of throttle motor assembly and cannot be replaced separately. If there are problems with the throttle control motor or the TPS the complete throttle body must be replaced." I know I've encountered outright mistakes in Haynes manuals before. Can someone confirm that I can or can't replace just the sensor?
