Gebo Posted September 14, 2009 Share Posted September 14, 2009 OK, I've had my '98 since '01. Best Car I have ever had! One issue I have always dealt with is this. When I start out from a complete stop, I mash the accelerator and not matter how I try, it will jerk the car. It seem I can't depress the pedal gently enough to get a smooth takeoff. My Daughter's IS300-no problem. My Wife's GS300-no problem. My LX470-no problem. My LS400 will jerk your neck it's is so bad. Any ideas?

1990LS400 Posted September 14, 2009 Share Posted September 14, 2009 Your car has been doing this for eight years and you have never had the problem diagnosed? :whistles: I might start at the accelerator pedal and have the PPS and TPS checked.

Yeah, I didn't know any different 8 years ago and I have just gotten used to it. It's only when someone else is with me do I "notice" it. How do I check PPS and TPS?

1990LS400 Posted September 14, 2009 Share Posted September 14, 2009 How do I check PPS and TPS? With an ohmmeter after disconnecting them. PPS: Resistance between terminals VC and E2 should be 1.64 - 3.28 kilohms at 20° C (68° F) TPS: Resistance between terminals VC and E2 should be 1.25 - 2.35 kilohms at 20° C (68° F) Quote Link to comment Share on other sites More sharing options...

Where is the PPS and the TPS? I can do the ohms. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted September 14, 2009 Share Posted September 14, 2009 OK. Where is the PPS and the TPS? I can do the ohms. They are under the V-Bank cover. Quote Link to comment Share on other sites More sharing options...
