BA_GS400 Posted December 27, 2004 Share Posted December 27, 2004 I was hoping to install my own TPS sensor, assuming it was not going to be any more difficult than on my other Fuel Injected rides. I have the sensor now, but I've been informed that the Lexus uses a "throttle blade angle" test tool or something like that instead of setting the TPS via a digital multimeter and specific voltages. Can anyone (guytelefunken?) shed any light on this, or as to whether I will be able to even do this myself? My dealer wants $115. Thanks!

TurboGS300 Posted December 27, 2004 Share Posted December 27, 2004 Why don't you take that $115 and buy a service manual, since you like to do things yourself, it will prove invaluable and save you lots of money in the long run. <_< Quote Link to comment Share on other sites More sharing options...
GuyTelefunken Posted December 27, 2004 Share Posted December 27, 2004 The part cost is about. $80.00. If it were me, I'd let the dealer do it if I didn't have the tools. You need a Lexus Handheld Tester or any OBDII compliant scantool that can display throttle position DATA as a %. GS4xx_TPS.pdf Quote Link to comment Share on other sites More sharing options...

B) I would *absolutely* do that, but at the moment, I was concerned about the extra cost of a special tool that I may never use again. :) There are no voltages listed in the service manual. Incidentally, I do know someone with an OBDII scan-tool. I will check into whether it displays throttle position as a percentage. If it doesn't, I'll hit the dealer. (or see how much a scan tool costs!) Thanks a bunch guys, even you Turbo GS300. <_< Quote Link to comment Share on other sites More sharing options...
ColinBarber Posted December 28, 2004 Share Posted December 28, 2004 Scan tool that plugs into a PC will cost under $100 so works out cheaper and will save you money in the future. If you don't have a PC (ideally a notebook so you can carry it to the vehicle) then stand alone units are available but will cost you much more. This is the one I use and gives you the throttle % required to adjust the TPS: http://www.obddiagnostics.com/ Quote Link to comment Share on other sites More sharing options...
