Rob Bice Posted November 1, 2009 Share Posted November 1, 2009 I have a 93 ls400 with a code for a RPM sensor . I think it is for the no.1 sensor. Does anyone know where these are? Is this what is causing my car to hesitate while I am driving it down the road? I have not pinpointed the RPM that this is happening. Any help or advice would be great. Thank You, Rob Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted November 1, 2009 Share Posted November 1, 2009 I found a knock sensor but nothing called an RPM sensor on this website: http://www.toyodiy.com/parts/p_U_1993_LEXU...1.html?hl=89615 Maybe you could look around the above website (there is a search feature on it too) and see if you can find the part.

Rob Bice Posted November 2, 2009 Author Share Posted November 2, 2009 When I got this car I noticed that a wiring harness at the front of the head on the drivers side near the fan belt had been rubbing on the belt. I tied it up out of the way and did not do anything else about it. I was wondering if this was the RPM sensor or something else.
