Gs450H Engine Not Incresing Rpm When In P Or N

[rikardo82]

Hi, I just wondering is that normal that my 2006 gS450H not increasing engine RPM when in P or N accelerator pedal is like dead when driving all OK

I have techstream software 2 errors are about solar sensor circuit thats it (did full health check). In live data it show accelerator position if I press more down it show accelerator postion change but no increase in RPM??? I tested other GS450H and then rpms increased somehow in P position. Also 2 days ago did MOT then also RPMS increased they tested emissions.

Yes it is normal, to increase RPM for MOT you nave to exclude TCS so RPM can rise.

About solar sensor , you have error if no sun :-)

This is normal operation. Throttle position does not directly relate to engine speed, like normal cars. Only a small rise in revs is noticeable.

During an MOT, the emissions are NOT tested as it is a Hybrid. This is exempt as the tester cannot override the system to petrol only.

some times it was not increasing RPM at all sometimes increased RPM slightly, it's possible also override hybrid system just have to push accelerator when in P and engine start if it was in hybrid electric mode at that time.
