GPSdependent Posted September 24, 2008 Report Share Posted September 24, 2008 A month after installing the Avic F-900 in my Lexus GS300, the car started failing; "poor throttle response" was the "symptom" according to the repair shop. They ended up repairing the throttle body, by replacing the throttle motor and the throttle pedal position sensor. In doing so, they found the unit's (the Avic's, that is) wire that was connected to the speed sensor, and disconnected it, saying that it "might" have had something to do with the problem. Has anybody had this problem? The repair shop told me they would re-connect the wire to the speed sensor if I wanted them to, but I'd rather do some more research before they do so... I would hate to have to have the car repaired again if that connection indeed had something to do with the problem! The unit seems to work fine without the wire to the speed sensor. However, I understand it loses some accuracy when in tunnels, etc. Any help will be appreciated. Thanks! Quote Link to post Share on other sites
ryan420 Posted September 24, 2008 Report Share Posted September 24, 2008 the vss wire will not cause poor throttle response...it picks up the signal from the vss signal from the transmission..or u could use the wire from your abs system Quote Link to post Share on other sites
HiFiSi Posted September 24, 2008 Report Share Posted September 24, 2008 Wouldn't effect it one bit. Quote Link to post Share on other sites
03Aviator Posted September 27, 2008 Report Share Posted September 27, 2008 Although unlikely, there is a possibility it could affect it. For example, if the VSS was tapped into the system improperly, or in an improper spot, the possibility does exist that it could cause other issues. I would say some research wouldn't hurt. How about finding a Lexus forum and see what others have done and if they have experienced any issues. Quote Link to post Share on other sites
