thenewmexican Posted November 1, 2008 Share Posted November 1, 2008 I looked at the How to Replace & Adjust the Throttle Position Sensor 1990-1994 Lexus LS400. In the picture showing the TPS. There is only one. However. On my car. There appears that there are two throttle position sensors. Can someone elaborate on this. Thanks.

thenewmexican Posted November 1, 2008 Author Share Posted November 1, 2008 Never mind. I googled and found the answer. The TPS nearest the engine is the real TPS. The other is for TRAC control. Quote Link to comment Share on other sites More sharing options...
